The api to mark the item as 'read' has slightly changed as on July 15, 2007. The name of the post parameter for token is 'T' and not 'token'.

Also to mark the item as 'read', you would need to pass parameter 'ac' with value 'edit-tags' and 's' with value of the feed url containing the item.

for e.g.

$req = POST $baseUrl, [

i => $guid, s => $url, a => 'user/-/state/com.google/read', ac => 'edit-tags', T => $token

];

Thanks for posting this! Seems like the API has changed a bit since Niall Kennedy's original article.

In playing with the API tonight, it seems like you have to be logged on in order to get any feeds from GReader...even the http://www.google.com/reader/atom/feed/http://xkcd.com/rss.xml link above seems to require that you are logged in. Has anyone else noticed the same thing?

From the doc, I can't find a way to get the list of feeds subscribed... is that possible?

Sorry for duplicates comments. System bug.

I now know how to get the list of feeds subscribed... It was changed to: http://www.google.com/reader/api/0/subscription/list

The list of unread items count was also changed to: http://www.google.com/reader/api/0/unread-count?all=true

Unfortunately I still can't find a way to get the next 20 items after the first fetch... Maybe is through continuation POST var?

I seem to be misunderstanding some stuff... I checked, the continuation is used to get the next items (just like said in the doc). Thanks for the wiki.

note that ck (timestamp) is the standard unix timestamp, with the addition of milliseconds, so instead of 1189800875, it would be 1189800875112

for atom items, the get parameter r (sort order) can also have the value "n" which seems to be a synonym for "d". so "o" is oldest first, "n" is newest first, "d" is descending.

Is there a way to filter a feed searching for a word? something like:

http://www.google.com/reader/view/user/-/label/important/#search/find_my_word

Is there a way to filter a feed searching for a word? something like:

http://www.google.com/reader/view/user/-/label/important/#search/find_my_word

If I pass in the contents of <gr:continuation> as a parameter (c=...), it does jump me down the feed, but always to the same point (maybe post number 40).

Also, if i use n as a parameter it doesn't work for values over 9.

Are these bugs, or am I doing something wrong?

token is actually T= not token= remember it is s=feed/FEEDURL not just s=FEEDURL

What about http://www.google.com/reader/public/atom/user/<uid>/label/<label>

This is the pure RSS atom feed of any tags you make public. It only returns the last 20 entries of the feed. Is there a way to make it return all the entries?

How can I get a URI like "https://www.google.com/reader/public/atom/feed/<feed URI>"? Or "http://www.google.com/reader/public/atom/feed/<feed URI>"? Is this structure just like "/reader/atom/feed/<feed URI>" that is used to request any feed from google reader system? If so, is there any fresh time of google reader system about this <feed URI>? Or fetch the content from <feed URI> and send it to the client just when user request it?

There seems to be lots of other API changes too. For example, for adding a subscription, google reader uses http://www.google.com/reader/api/0/subscription/quickadd?client=myclient with postdata as quickadd=<URL>&ac=subscribe&T=<TOKEN>

I think they might have changed more, and this document might need reviewing.

I'm wondering if they're planning to release an official API someday :(. I'm working on a little Java program to manipulate my unread items, but it's quite painfull right now...

To get feeds beyong 20 feeds pass n=<numbertoretrieve> as GET request. Unfortunately I didn't figure out a way to start the feeds from a given number.

For example: http://www.google.com/reader/atom/feed/http://xkcd.com/atom.xml?n=20

I'm working on an unofficial Java API for Google Reader based on this page's information.

Requierements is spelled requirements

Is there any way to get the specific extensions in each feed? I'd like to be able to view the original itunes extensions through Google Reader because they keep history, but it seems like they strip them out; i.e. it's a bare-bones atom feed.

Is there any way to login in google-reader account by java program only?Means from code, not from google-reader homepage.Ia m sending "Email" and "Passwd" as post parameter to https://www.google.com/accounts/ClientLogin.Then I am getting SID and LSID.Then I am dumoing cookie.But,its not taking setDomain(".google.com") method. What to do? I want to be logged in via code.IS therer any mistake I am doing?Plz help!!!

@swetadri: I'm currently working on it, if you want more info and/or help me, you can contact me at lechtitseb at gmail . com

The "xt" parameter seems to work only for excluding read items. It seems to completely ignore other states, labels, or feed stream IDs beginning "feed/".

Does anyone have a workaround for this?

I have made my own java based google reader api. Theres no documentation, and it is incomplete, but it may be useful for someone. http://www.caip.rutgers.edu/~scarvel/grapijava/

thanks to scarvel8...ur api is useful to me...

scarvel8, did you do the same thing for subscribtion via my yahoo or bloglines?if yes, please let me know

No I haven't, although if I get some free time I will look into it. I am also working on other options not listed in this document, such as being able to load search results. I should have a more complete API up in the next week or two.

ok..if you do for yahoo rssfeeds, plz tell me...

I am trying to access this url with an XMLHttpRequest: http://www.google.com/reader/atom/user/-/state/com.google/broadcast

However, the responseText is a Google error page which says the following: "Further action needs to be taken by your user agent in order to fulfill the request. "

The script goes through a PHP proxy so it can go cross domain. Does anyone know what information Google Reader requires that would fix this error?

Great article! I want to export my google reading list, and a step is to input it into a feedburner feed for further processing. I could not get Google to export the feed, with the correct userID: http://www.google.com/reader/atom/user/123456789123456789123456789/state/com.google/reading-list Is there authentication requirements?

Ok.. answered my own question. I tried a GET with https://www.google.com/accounts/ClientLogin?service=reader&Email=myusername&Passwd=mypassword and got the authentication requirements parameters

Hi thanks for the post.Nice blog.Now this blog is in my favourite bookmark pages. http://www.squidoo.com/papershredderarticles

I out together a very small program that shows a basic way of grabbing GET data from Google Reader with Java. I commented it up so most questions should be answered. Note this is VERY basic, and just intended for people looking for information on how to get started.

http://www.foreverzero.org/Process.java

Has anyone been able to successfully implement the continuation parameter for getting more feed items from a feed? I cant seem to get it to work. The url I create I can put in a browser address bar and it works fine but when I hit it from a server (CURL) it always shows the first n items.

Also, I cant seem to get any of the xt (exclude) links to work. Has anyone pulled this off?

(http://www.google.com/reader/atom/?n=4&xt=user/-/state/com.google/read)

i can read N items from a feed.. i am currently limited by heap size only, yay

i can also query for number of unread items but have no implemented (in java) the ability to mark items as read.. any advice?

I can't make it retrieve more than 999 items from a given feed. Any ideas how I might get more than that?

(I have a few years' worth of friends' facebook status updates cached in Reader, and would love to be able to export them all! http://infoclarity.blogspot.com/2008/06/hidden-in-words.html)

Thanks for the great tips.

Ok, you can probably tell I'm a complete noob at this from my question but here it goes. I'm just trying to make a very simple bash shell script using curl to get my unread count. I can view the data I want just fine when I open this link in safari (http://www.google.com/reader/api/0/unread-count?all=true) and I can view the source and see exactly what I'd like to extract. However, when I use curl in my shell script it doesn't work. I'm assuming I have to login as described at the beginning of the article to access this data using curl. My stupid question is this: is it safe/secure to include my user name and password in this url ( https://www.google.com/accounts/ClientLogin?service=reader&Email=myusername&Passwd=mypassword) in a shell script? Any suggestions would be a big help. Thanks!

For doing any operation which requires authentication, you would need to provide two tokens:

SID Authentication token or T token (do not mix up this token with the Auth token you get by authenticating against Google by ClientLogin?)

SID (session ID) is a session token. There are also two ways of fetching this token:

If you have a browser (i.e Firefox) opened and already logged in any Google site, a valid SID token would be stored inside your browser. Firefox stores session tokens inside session_store.js file. In conclusion, search for the SID inside session_store.js if there is any google session opened inside your Firefox.

Authentication against Google reader service using ClientLogin? mechanism. Google reader service codename is 'reader'. ClienLogin? mechanism is fully documented by Google (just google it). ClientLogin? mechanism returns three tokens, one of them is SID (session token).

Once you got a valid SID token, then you need to retrieve

Once you get a valid SID token, do a GET request to the following URL to get a valid T token.

http://www.google.com/reader/api/0/token

This request should be composed by adding SID as a Cookie.

Once you get both tokens, SID and T, you can successfully perform any Google Reader operations which require authentication (pass these two values as cookies)

So answering the question above, how to compose a valid curl command to fetch a list of unread elements:

First, get a valid SID token:

curl https://www.google.com/accounts/ClientLogin -d Email=just_your_username_here_without_at_gmail_dot_com -d Passwd=your_password_here -d source=Google-cURL-Example -d service=reader

Response: Auth=XXX SID=DQAAAH0AAAC0YHom0L5LDq10xGnbQK_O7OLiX3Qrou4XeA6P469shoM1goEFQT_zVn8YxDV38Y5v3mGJlhSzJuz5xLPqpKEM0Wedks-ak7LLpNjO7dZw779ljOQrC-2UCYFjiktJcfXmof7WeZs7O0SCNCQgPSKaENJ6FBTeDBeQLahUUrajrg LSID=XXX

Once you get a valid SID, request a T token:

curl -s -X GET http://www.google.com/reader/api/0/token --header "Cookie: SID=DQAAAH0AAAC0YHom0L5LDq10xGnbQK_O7OLiX3Qrou4XeA6P469shoM1goEFQT_zVn8YxDV38Y5v3mGJlhSzJuz5xLPqpKEM0Wedks-ak7LLpNjO7dZw779ljOQrC-2UCYFjiktJcfXmof7WeZs7O0SCNCQgPSKaENJ6FBTeDBeQLahUUrajrg"

Response:

kArWxxwBAAA.vegUbtUjv2Vvf_HKWlwjIA.QfhP1LoSb5ghYPz_AbOG_Q

Once you get a valid T token, perform any operation you want against Google Reader, for instance, retrieve your list of feeds

curl -s -X GET http://www.google.com/reader/api/0/unread-count?all=true --header "Cookie: SID=DQAAAH0AAAC0YHom0L5LDq10xGnbQK_O7OLiX3Qrou4XeA6P469shoM1goEFQT_zVn8YxDV38Y5v3mGJlhSzJuz5xLPqpKEM0Wedks-ak7LLpNjO7dZw779ljOQrC-2UCYFjiktJcfXmof7WeZs7O0SCNCQgPSKaENJ6FBTeDBeQLahUUrajrg; T=kArWxxwBAAA.vegUbtUjv2Vvf_HKWlwjIA.QfhP1LoSb5ghYPz_AbOG_Q" | tidy -xml -indent -quiet

Following the curl breadcrumbs of pinowsky (thanks!) I worked up the following Python code to use Google Reader to convert feeds to Atom:

http://wiki.xml3k.org/Amara/Recipes/Google_Web_feed_atomizer

From now it seems like I need to be logged in to access atom/feed/somefeedurl?

I can't use command-line URL-fetchers (like 'wget' or 'GET') successfully when trying to access the following URL: http://www.google.com/reader/atom/feed/http://xkcd.com/rss.xml

They don't return XML data, but rather an HTML page telling me to log in. Is Google restricting access to particular user-agents (browsers)?

Google Reader has feed translation, introduced 2008-11-11.

That's accessible by the parameter/key pair of "trans=true"

ex. http://www.google.com/reader/atom/feed/SOME_FEED_URL?trans=true

the above translates to the language of your setting with Google Reader.

I don't know if you can make it translate to languages of your choice just by varying a parameter.

Is "edit-tag" still working?

I got a "400 client error" when I try to add a label to a specific post of my favorite list. I got a valid SID and Token, but for exemple this URL is not working: http://www.google.com/reader/api/0/edit-tag?ac=edit&i=tag:google.com,2005:reader/item/041fa449c5de72c9&a=user/-/label/test&token=97xa1B0BAAA.RDpLb8-l3NMfqpaw0vYq-g.JcgYUQXFh9E6MmkLNIpwEw

Am I missing something?

Hi,

I am wondering how to sync with GoogleReader?? for offline reading? I want the latest 10 entries that I haven't seen before, e.g. r=d (date descending), n=100, ot=<timestamp of last sync>. But you say above that specifying ot only works with r=o. ;-(

Cheers, Mariano

Hi Mariano -- What you're going to want to do is use the "xt" (exclude target) parameter to exclude read items in your query. Look for "xt" above.

Hi TrashingStick?, I appreciate very much that you took the time to post an answer. I thought nobody would ;-(

But this would not help me really. It is not the same to have donwloaded an item and have read it. So I download a couple of items to a mobile device, read some of them, but then don't want to download the unread items all over again every time I sync. It is also not an option to mark them as read anyway and keep a separate read state on the client. This would make the items marked read for the online reader also.

Any more ideas?

I opened a question on stack overflow: http://stackoverflow.com/questions/384771/how-to-skip-known-entries-when-syncing-with-google-reader

the start_time parameter no longer (or never) works.

no matter what start_time i set, whether r=o or r=n, the oldest feed item returned is within this month.

oh well. if anyone tries to grap all the items. the way is to set n very very big so that it covers all the items.

Will somebody pl tell me - 1. how to mark an item as read (using these api) 2. how to mark many items as read (using theser api)

I tried whatever has been said above.......however not getting it right. Pl explain with an example.

Thanks a ton in advance -shabda

Does anyone know how to solve this...?

I'm trying to roll my own aggregator by running feeds through the API to normalize the contents. Works great for most feeds ("http://www.google.com/reader/atom/feed/#{feed.url}"). However, some feeds use url parameters to deliver their contents... example: "http://img.perezhilton.com/?feed=rss2". The API sees this and thinks the feed address is just "http://img.perezhilton.com/", and that the "?feed=rss2" is a parameter for IT, rather than the feed's server. Escaping the ? does not work... anyone have any clues?

Thanks to all for the awesome work figuring this out.

jackphelps, try urlencoding the whole url:

http://www.google.com/reader/atom/feed/http%3A%2F%2Fimg.perezhilton.com%2F%3Ffeed%3Drss2

this seems to work :). Good luck with your project

I'm getting 401 (Unauthorized) HTTP error, when trying to call "edit" API methods. I've tried to attach "T" token both in post request and as cookie to no avail. Does anyone else get the same error?

I'm have the same problem (401 (Unauthorized))

Google don't allow to remove "user/-/state/com.google/read", and I failed to add "user/-/state/com.google/kept-read". Any tips on how to mark article "unread" now?

Thank you very much for this analysis, it was very helpful.

Here is my small tool written using Reader API (and some python code): managing subscriptions as a text file

katapulp - did you have any luck? I'm having the same issue. I've presented the i, s, & a arguments in every way I can imagine (in the url, as data in the post, URL encoded, not URL encoded) and the same with SID and token, and I always get a 400 or 401 error. Any one here have any luck editing tags? I can read data no problem, I just can't modify.

Hi, For all shared items, how can I get the list of tags for each shared item? I have been trying with the above api and so far unsuccessful. Any suggestions are appreciated. Thanks.

To catapulp and wayne.culbreth:

I have a working 'edit-tag' feature of marking entries as read in the following way:

Post to url: http://www.google.com/reader/api/0/edit-tag?client=- Post body: "i="+entryId+"&a=user/-/state/com.google/read&ac=edit&T="+token

Other combinations of T->token, ac=edit->ac=edit-tags, adding s=feedURL and so on come to 400 error from Google.

Hello guys ,

I am planning to write an application that simulates a Feed Reader and manager and I decided to write it in SIlverlight (it sounded interesting and I hope I will learn a lot).

My first problem was somehow to "generalize" the feeds brought into the application. After some research I found out Google Reader offers the posibility to access their first layer ( parsing layer) and in this way I could get the feed in atom format for any feed.

(using http://www.google.com/reader/atom/feed/[URL] command)

Ok ,things were clear until here .I already knew that for an SIlverligt appication to exist the posibility to extract some data from another location than it's domani ,that data site should have a crossdomain.xml file in the root of the site.

My thought was first that Google has something like this ,I also was enthusiastic when found reply to crossdomain.xml. But disappointment come soon because on a closer look the xml file looks like :

<?xml version="1.0"?> <!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/ dtds/cross-domain-policy.dtd"> <cross-domain-policy>

<site-control permitted-cross-domain-policies="by-content-type" />

So my first idea was to use a proxy to access this link ,I am new in this technology and tried some solutions:

SIlverlight can extract for example any data through a proxy ,for example this works: http://al.cloudapp.net/proxy.ashx?http://rss.cnn.com/rss/edition.rss ,it extracts the direct feed from cnn site even if they don't have a crossdomain.xml file.

My next step was to generalize the feed through Google Reader :

http://al.cloudapp.net/proxy.ashx?http://www.google.com/reader/atom/feed/http://rss.cnn.com/rss/edition.rss ,but this solution failed ,I also tried with different proxies and no success.

My questions would be:

1.Why Google has this crossdomain.xml file and not a more permissive one? Could it be possible to modify this crossdomain.xml so that Silverlight application can access this API?

2.If 1 is not possible does anyone have a better solution ,I feel I am very close and maybe it may work through a proxy and I am doing something wrong?

3.Anyone else have any other ideas?

Thanks a lot, Ionut

Hello. Just found this and have only begun digging in, but my first simple test is failing and it seems to be a "mad-made" issue. Google Reader shows that I have 84 unread items, yet the following code only returns 20 entries:

xmlfeed = gr.get_all()
print xmlfeed.get_title()
for entry in xmlfeed.get_entries():
    print entry

I see a 'count' parameter in ATOM_ARGS which may be used to limit the number of items (?) and "20" is a suspiciously convenient and round number, but I dont see any reference to 20 in the code... Is the response limited to 20 items?

Has anyone looked into emulating the ability of the bookmarklet they release (http://googlereader.blogspot.com/2008/05/share-anything-anytime-anywhere.html). It allows you to share an item even if it isn't in one of your feeds. Would be nice to be able to duplicate this in the code too.

Mine works for a little while, but then I get a 302 redirection and the message "Further action needs to be taken by your user agent in order to fulfill the request." After some period of time (I'm not sure how long yet) it will start working again.

If anyone aware of a limit to how often you can access the API during a period of time. I always get to a similar point (>100 I think) before getting the redirection.

I've already queried atom feeds from it several thousand times in testing my app. Seems to be no problem there.

Does anybody know how to eliminate duplicates of entries which google returns sometime with the http://www.google.com/reader/atom/ API? This often happens when the RSS creators update entry, but the URL or id of the entry is changed. The same feed explored with Google Reader web interface doesn't contain duplicates, which appear with Reader API. While Google Reader is based on the GoogleReader? API it should be possible to avoid duplicates with API too.

How can I get a list of unread news (with the title)?

Trying to make edit tag work. I've got the data to be sent by using Firebug in Firefox and using online Google Reader. The result is return of "Invalid stream name." Anybody knows what that means?

Hey i am getting a 400 error when i try to add a subscription list to google reader. Here is what I am doing

url = "http://www.google.com/reader/api/0/subscription/edit?client=-"

I set my http request url to this

and pass the following post parameters

postRequestPayload=feed/http://xkcd.com/rss.xml&ac=subscribe&T="+token.

I have also tried token instead of T and also tried client=scroll in my url but I still get the 400 error. Please help.

The official Google Reader desktop gadget uses the API, so accurate API information can be gathered from it: http://code.google.com/p/google-reader-gadget/

I was using the following url http://www.google.com/reader/atom/feed/http://.. to be able to download all the feeds that i would eventually miss when my RSS Client is off. Why is not working any more?? I get this error in safari: “The feed could not be loaded because the content is not in a known feed format.” (PubSub?:2)

Fixed. The problem was something regarding cookies. I just needed to logout, delete the cookies in safari and login again. I recommend to use those url if the feed you're watching has more than 20 updates per day as the Client/feed might not pick more than that. -GianPaJ

I am using this URL to get unread headlines: https://www.google.com/reader/atom/user/-/state/com.google/reading-list?xt=user/-/state/com.google/read

Is there a query string parameter to exclude elements like <summary>? That would mean I would download a lot less data.

I discovered that the "broadcast-friends" state is for items that your friends have shared (i.e. are in the People You Follow section).

My HTTP requests to Google Reader API return HTTP 403 response. Everything worked fine until i've started experiment to check for new entries in cycle for about 4000 feeds. It looks like some kind of ban but i can't find any published restrictions on service usage. Does any body know about restrictions or about the way to pass the problem without changing the IP?

I have found the JSON version of /reader/atom/user/-/state/com.google/reading-list if anyone is interested:

http://www.google.com/reader/api/0/stream/contents/?xt=user/-/state/com.google/read

Everything was working fine, and then I started getting the message "Your client does not have permission to get URL /reader/api/0/token from this server," when requesting a token despite not having changed any code. Has anyone else experienced this?

@dmatarazzo I'm having the same problem. =\

@ruimams I figured out that the problem was with how I was setting up the cookie that contained the SID. Could that be the source of your problem? As long as you're using POST, sending a cookie (I sent mine through the header) that reads SID=SID here? and using the /reader/api/0/token URL, it should work...

Since there isn't an "unread" state, to get a list of all unread items just query your reading list with a very large number and exclude read items like so: http://www.google.com/reader/atom/user/-/state/com.google/reading-list?n=9999&xt=user/-/state/com.google/read

How do you "mark as read " ?

I've tried sending : URL : http://www.google.com/reader/api/0/edit-tag Post values : i = tag:google.com,2005:reader/item/03052da1635b7fdb a = /user/-/state/com.google/read T = token value I include the sessions cookies as well.

Thanks.

Answering my post above. I had a slash in front of 'user' in the 'a' tag. 'ac' tag is set to 'edit-tags'. URL encode the token, 'i', and 's'. It works now.

This is great!!! Can we use this API for a commercial product? Can someone at google respond to me cyberprashant at gmail dot com. Thanks!

Hello,

I'm working with .NET, and I looking .NET component tall with Google Reader API

Now, I use component at: http://mattberseth.com/blog/2009/02/net_googlereader_api.html

In my code, I get rss from google news but have error - bad request

http://www.google.com/reader/atom/feed/http://news.google.com/news?cf=all&ned=us&hl=en&q=obama&cf=all&output=rss

How to fix this error?

Pls help me!

Nice article. Just tried it to get all my feeds on Google reader.

Thanks.

@ng2tuan:

Try urlencoding the feed URL. The ? is your problem.

I've had my server checking feeds using the Google Reader API for a long time now and all of a sudden I'm getting 302 redirections because it's coming from an automated script. Is anyone else seeing this?

I've been fetching feeds directly from Google so I can have the Google ID's for each item to promote syncing. If anyone knows of another method for this I would love to hear it.

I have installed everything just as indicated, but obtain the following error when trying to run pyrfeed.py: AttributeError??: 'module' object has no attribute 'EVT_BeforeNavigate2?? Any ideas? Thanks,

Gonzalo

Does Google change the api? My RSS reader for Android is work normally before. But It can't link and always return fail these days. Who can tell me why?

There's a feed discovery api in json or atom.

You can get basic feed finding information as either Atom or JSON: http://www.google.com/reader/api/0/feed-finder?q=http://www.boston.com/bigpicture/&output=atom http://www.google.com/reader/api/0/feed-finder?q=http://www.boston.com/bigpicture/&output=json Once you have the feed URL you can get stats for it as XML or JSON (note that this requires you to be logged in): http://www.google.com/reader/api/0/stream/details?s=feed/http://www.boston.com/bigpicture/index.xml&output=xml http://www.google.com/reader/api/0/stream/details?s=feed/http://www.boston.com/bigpicture/index.xml&output=json Mihai Parparita Google Reader Engineer

post url: http://www.google.com/reader/api/0/subscription/edit

post parameter: Cookie:SID=mysid client=- s=feed/http://rss.sina.com.cn/news/marquee/ddt.xml ac=subscribe T=mytoken

response:http 401 error

Missing any parameter?url changed?

When can we have a offical document for google reader api?

If anyone is interested there is also output=proto for outputting in Google's own Protocol Buffers binary format. For example, http://www.google.com/reader/api/0/unread-count?output=proto

This is what I have been looking for long time.

Anyone know how to get all articles changed since a given date/time? Ie, I want not only new articles since a given date, but also any articles that had a state change such as read, unread, favorite, etc.

Just need the .proto files now to be able to decode the protocol buffer API responses. I have tried searching for them with no success yet.

Just created a tiny ruby test script for accessing the API to add / remove subscriptions and labels in my reader. (Will use this functions later on in an other script). I also used the Authorization-Header-Authentication instead of Cookie-Authentication.

If someone is interested in this script you can see it at http://gist.github.com/341399

Is authentication still a problem for reading an user's data in Google Reader?

Can't AuthSub? or OAuth be used around this to get access to data without providing username and password?

'n' is limited to 1000. If you need to get more items than 1000 you have to use 'continuation'. So annoying.

Sample PHP code for adding/removing a feed (see above for getting session ID and token):

// adding a feed
$ch = curl_init();
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_URL, "http://www.google.com/reader/api/0/subscription/quickadd?client=scroll");
curl_setopt ($ch, CURLOPT_COOKIE, 'SID='.$this->session_id);
curl_setopt ($ch, CURLOPT_POST, 1);
//curl_setopt ($ch, CURLOPT_POSTFIELDS, array('quickadd'=>urlencode($feed_url),'T'=>$token)); // will not work
curl_setopt ($ch, CURLOPT_POSTFIELDS, 'quickadd='.urlencode($feed_url).'&T='.$token);
curl_setopt ($ch, CURLOPT_USERAGENT, $this->user_agent);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$content = curl_exec($ch);
curl_close($ch);

// removing a feed
$ch = curl_init();
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_URL, "http://www.google.com/reader/api/0/subscription/edit?client=scroll");
curl_setopt ($ch, CURLOPT_COOKIE, 'SID='.$this->session_id);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, 'ac=unsubscribe&s=feed/'. urlencode($feed_url) .'&T='. $token);
curl_setopt ($ch, CURLOPT_USERAGENT, $this->user_agent);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$content = curl_exec($ch);

google add a statue 
State name: created State meaning: A read item will have the state create. url:http://www.google.com/reader/atom/user/-/state/com.google/created

this is user comment items.

google modified the access param "token" to "T" for "www.google.com/reader/api/0"

"/api/0/token" will return a string containing 22 chars

How can I filter (or search) the feed results based on a keyword search, similar to how you search in google reader?

I am able to get the following results from a shared feed that I’ve made public. I actually get the same results with the following 2 URL’s (notice the first has “public” in it.

http://www.google.com/reader/public/atom/user/02147574221729223002/bundle/Fantasy%20Football%20NFL%20Articles?n=10

http://www.google.com/reader/atom/user/02147574221729223002/bundle/Fantasy%20Football%20NFL%20Articles?n=10

Lets say I wish to filter the results above based on a keyword, "Roethlisberger".

When I search a folder using the search form in reader, the url shows as:

http://www.google.com/reader/view/#search/Roethlisberger//user%2F02147574221729223002%2Flabel%2FSports

If I change the reader tag to “atom”, the results are incorrect.

Thoughts? -Gurpreet

Hi, I am trying to use the reader api to get feeds that I have been tracking since early 2009. However, I noticed that my feeds seem to only read 1000 items before a limit is reached. Is there some setting that allows one to access feeds with a much higher maximum number count?

Hi, Any idea how to search for a particular entry guid, or original-id?

I know the original-id and I want to make updates to the google version, how do I map between? Thanks, T

Is cookie SID a secure thing? I get it via /accounts/ClientLogin?, then i unvalidate it via /accounts/Logout, but stil can feach private data with curl -H "Cookie: SID=$SID" ... What about, if anyone found one of my SID strings?

Hey everyone,

I'm getting 400 errors when trying to star an item, and I can't figure out why. Here is the URL:

http://www.google.com/reader/api/0/edit-tag?i=tag%3Agoogle.com%2C2005%3Areader%2Fitem%2F97e73baae1c833d6&s=feed%2Fhttp%3A%2F%2Fwww.slickdeals.net%2Frss.php&a=user%2F-%2Fstate%2Fcom.google%2Fstarred&T=_2g76ZvXODPljRi-gCP42A

I've also tried passing ac=edit, ac=edit-tags, and URL Encoding and not URL Encoding variables. I am passing the SID as a cookie, and all my queries work fine, such as getting unread lists and items. But as soon as I try to use the edit-tag api it fails.

Ideas?

Any new opinions on how to subscrie to a feed ? I'm using C#:

I create a http web request with POST here: http://www.google.com/reader/api/0/subscription/quickadd with GET params : client = scroll and ck = ... and POST params : quickadd = feedURL, T = token

I attached the cookie and pust an user agent to the request, but I still get 401. Is there someone who has succeeded in making this request ? I've double checked with these params using Firebug, but still no succes

hey can anyone tell me about how to get 'ot' value?

Hi!

This wiki page greatly helped me in writing my own application for reading rss news. (I might publish it soon).

My application was working fine for couple of months now. However, google reader responses started to return information about authentication requirement. Logging in is still successful and SID cookie is created the same way.

Does anyone know what might have changed?

This seems to be broken as of June 2010 . My app which has worked for months is now getting a unauthorised from googles servers... Hopefully we will get an official API soon...

I have just found http://www.google.com/support/forum/p/reader/thread?tid=5698d3dc3cfa4470&hl=en which points to: http://groups.google.com/group/fougrapi/browse_thread/thread/e331f37f7f126c00

I have not tried to use it yet.

Using:

 Authorization:GoogleLogin auth=[value obtained from ClientLogin] 

works :)

header

name : Authorization value : GoogleLogin? auth=obtained from ClientLogin?

Authorization:GoogleLogin? auth=obtained from ClientLogin?

How to use that?

Add the following header to your HTTP request. Name: "Authorization", Value: "GoogleLogin? auth=<ADD AUTH TOKEN HERE>"

Does anyone have a complete header request? My requests were working with SID, but I've tried adding the headers as above with/without my old SID header and my new auth. I'm getting 400 error.

I've had the same problem as of a few days ago and can't resolve it. Tried the GoogleLogin? in the header and still get a 401 when requesting a google reader URL that worked fine for weeks before. Anyone else get this resolved? Did you completely drop the SID? Is a space ok in the header between Authorization and GoogleLogin??

when you get the SID at https://www.google.com/accounts/ClientLogin, there is now a new additional parameter 'Auth'. you need to extract it and use it in the HTTP request header of every request to the google reader in the following way: add a new header variable 'Authorization', where its value is 'GoogleLogin? auth={here add the Auth variable you got from where the SID is}'. all the rest stays the same!

i cant get my app to work with new auth method: is still required the GET call to http://www.google.com/reader/api/0/token or the auth= value received from GoogleLogin? can be used as token my try was 1) save the valued of ath, add header, call api/0/token = error 403 2) save the valued of ath, add header call directly reader/api/0/subscription/list?client=pushNews&output=json = error 401

since few days ago all was working with SID+token

For those using the cookie method, this is working for me:

"Cookie: SID={sid string}\r\nAuthorization:GoogleLogin? auth={auth string}"

Be sure to remove the '?' after 'G00gleLog1n?'

im quite sure to do all correctly, but still got error :(

is there someone that is able to retreive api/0/token with iphone sdk ??

this's the routine: SID (no more useful) and Auth correctly read with /accounts/ClientLogin?

try to retrieve the token: request = [alloc? init];

url = stringWithFormat:@"http://www.google.com/reader/api/0/token"?; //url = stringWithFormat:@"http://www.ericgiguere.com/tools/http-header-viewer.html"?; setURL:[NSURL URLWithString:url?]; setHTTPMethod:@"GET"?; setValue:[NSString stringWithFormat:@"GoogleLogin auth=%@", AUTH? forHTTPHeaderField:@"Authorization"]; NSLog(AUTH); //is correct setHTTPShouldHandleCookies:NO?; setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"?; risposta = sendSynchronousRequest:request returningResponse:&response error:&error?;

i still got error 403

thanks for any tips

my God, 2 days lost for a stupid error: i was not stripping the last linefeed in the response of ClientLogin? now with posted routine all is ok

I can not change read/unread by edit-tag. But I can get token correctly. Can anyone tell me why? Thx a lot !

I am trying to convert a feed to atom using Google Reader and then saving it locally to my server.I am using a php script with curl.No matter what i have tried the saved xml says that further action needs to be taken by my agent.I have already logged in to Google with curl and have retieved SID, Auth and token (event though i don't need them all for accessing layer 1) and i have used both the header method and the cookie method but still Google does not allow me to save the result to a file.I have googled around but i haven't found anyone attempting this.The closest is this python feed converter http://wiki.xml3k.org/Amara2/Recipes/Google_Web_feed_atomizer Can anyone help?Thank you

Are we need is auth token in header now, we don't need to set cookie anymore. The follow is a example using java with apache httpclient:

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(url);
httpget.setHeader("Authorization", "GoogleLogin auth=" + authToken);
HttpResponse response = httpClient.execute(httpget);

I have the same issue, I had a working python script and now it not longer works returning a 401 auth error, with either old cookie based auth or the method mentioned above :(

I had a working python script and now it not longer works returning a 401 auth error, with either old cookie based auth or the method mentioned above :(

Here's the main code:

        url = "https://www.google.com/reader/api/0/unread-count?all=true"
        request = urllib2.Request(url, None, auth_header)
        response = urllib2.urlopen(request)
        unreadxml = response.read()

And here is the function that provides the Auth_header dict object:

    def getAuthorizationHeader(self):
        
        # Authenticate to obtain SID
        auth_url = 'https://www.google.com/accounts/ClientLogin'
        auth_req_data = urllib.urlencode({'Email': self.options.username,
                                          'Passwd': self.options.password})
        auth_req = urllib2.Request(auth_url, data=auth_req_data)
        auth_resp = urllib2.urlopen(auth_req)
        auth_resp_content = auth_resp.read()
        auth_resp_dict = dict(x.split('=') for x in auth_resp_content.split('\n') if x)
        SID = auth_resp_dict["SID"]
        
        # Create a auth key in the header using the SID 
        header = {}

        header["Authorization"] = "GoogleLogin auth=" + SID
        
        return header

Fixed the auth header function, had to use the auth key and not the previously used SID, also had to add the service key into the request:

    def getAuthorizationHeader(self):
        
        # Authenticate to obtain SID
        auth_url = 'https://www.google.com/accounts/ClientLogin'
        auth_req_data = urllib.urlencode({'Email': self.options.username,
                                          'Passwd': self.options.password,
                                          'service': 'reader'})
        auth_req = urllib2.Request(auth_url, data=auth_req_data)
        auth_resp = urllib2.urlopen(auth_req)
        auth_resp_content = auth_resp.read()
        auth_resp_dict = dict(x.split('=') for x in auth_resp_content.split('\n') if x)
        AUTH = auth_resp_dict["Auth"]
        
        # Create a header using the AUTH key 
        header = {"Authorization" : "GoogleLogin auth=%s"%AUTH}
        
        return header

Cant figure out why i couldn't make this PHP code work before, but it does now.Here's a php example on how to download and store locally the converted feeds.

<?php

$path = "GoogleFeed.xml";
$url = "http://your_feed_url";
$feed_url = "http://www.google.com/reader/atom/feed/$url?n=100";


//Parameters required to login to Google
$params = array('accountType' => 'GOOGLE', 'Email' => 'example@gmail.com',
'Passwd' => 'your_passwd', 'source'=>'PHP-cUrl-GooleLogin', 'service'=>'reader');

//Login to Google
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.google.com/accounts/ClientLogin");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
$googleResponse = curl_exec($ch);
curl_close ($ch);

//Retrieve the SID and Auth parameters for further Google transactions
$sid = substr($googleResponse,4,203);
$pos = strpos($googleResponse,"Auth=");
$pos = $pos+5;
$auth = substr($googleResponse,$pos,224);

//Connect to Google Reader and retrieve the user's feed in Atom form spanning at least 100 entry elements
$headers = array(
    "Authorization: GoogleLogin auth=" . $auth,
    "GData-Version: 3.0",
);
$agent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.7) Gecko/20100713 Firefox/3.6.7";
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $feed_url);
curl_setopt($curl, CURLOPT_USERAGENT, $agent);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_POST, false);
//Save Google Reader's response directly to a file
$fp = fopen($path, 'w');
curl_setopt($curl, CURLOPT_FILE, $fp);
curl_exec($curl);
curl_close ($curl);
fclose($fp);

?>

Is there a way to paginate the feed?

suppose, I setup my feed 20 per page using Atom set method, and now i want to jump to 5th page directly (that means, post 81 to 100).. is there a way to do that?

something like http://www.google.com/reader/atom/user/-/state/com.google/broadcast?n=20&page=5

is there a way to do this?

Hey,

can I get the feed with content that is not html formatted ? Or I can only get html formatted content from google reader, thanks

A few corrections (it seems the API has changed somewhat):

• the token parameter is now just T
• when adding a subscription with the s parameter, its URI has to be prefixed with feed/ (this is mentioned in the overview, but missing from the example)

To be continued...

Hello,

I have some problems to mark an item as read I have an error 400 or 401. I'm developping on Android and using JSoup to send the request

Thanks

Has anyone found a way to get sort by Magic working? Do any apps have this feature at all? Can't find it anywhere but on the GR site.

Hello,

Can anyone post a complete URL that works with the current API for marking all items as read? I have tried:

http://www.google.com/reader/api/0/edit-tag?i=tag:google.com,2005:reader/item/03052da1635b7fdb&a=user/-/state/com.google/read&ac=edit-tags&T=[token]

but I get a 401 error.

Many thanks.

I am very much pleased with the contents you have mentioned.I wanted to thank you for this great article. http://www.Craigslistz.org

string args="?i=tag:google.com,2005:reader/item/2ee53214436e17a5&a=user/-/state/com.google/read&ac=edit&T=//4Dk64M97g7q9Afbad301sA"

HttpWebResponse? response = httpPost("https://www.google.com/reader/api/0/token/edit-tag/client", args);

private HttpWebResponse? httpPost(string requestUrl, string postArgs) {
byte buffer = Encoding.GetEncoding?(1252).GetBytes?(postArgs); //byte buffer = Encoding.GetEncoding?(65001).GetBytes?(postArgs);
HttpWebRequest? request = (HttpWebRequest?)WebRequest?.Create(requestUrl); request.Method = "POST"; request.CookieContainer? = new CookieContainer?(); request.CookieContainer?.Add(cookie); request.ContentType? = "application/x-www-form-urlencoded"; request.ContentLength? = buffer.Length; request.Headers.Add("Authorization", "GoogleLogin? auth=" + auth);
Stream PostData? = request.GetRequestStream?();
PostData?.Write(buffer, 0, buffer.Length); PostData?.Close();
try {
return (HttpWebResponse?)request.GetResponse?();
} catch(Exception ee) {
MessageBox?.Show(ee.Message); return null;
}
}

it got "404 error"! who can help me!thx

It seemed that one can clear "state/com.google/read" state only if entry have "state/com.google/fresh". Otherwise read state is not cleared though request returns "OK"

for edit-tag reqiest you should send following post fields:

i - for id of item (eg. tag:google.com,2005:reader/item/b1b915a7dfa70337)

a or r - for add or remove tag name (eg. user/-/label/tagname)

s - for feed url of item starting with feed/ (eg. feed/http://habrahabr.ru/rss/)

T - for token

when using ios make sure you add

NSString authHeader = stringWithFormat:@"GoogleLogin %@", authString?;

addValue:authHeader forHTTPHeaderField:@"Authorization"?;

to every GET

Some specific behaviour: items in "starred" folder always have "fresh" label, so always can be marked as "unread"; if this very entry in original folder doesn't have "fresh" label, then unread states may differs in original and "starred" folders. If entry in original folder have "fresh" label, then unread state reflects such state in "starred" folder. weird. if you get entryes filtered by "starred" label, you cant'be sure if entry is in "read" state in original folder. seemes as some bug in GoogleReader? logic.

I'm trying to add a feed to my Google reader account with a call to http://www.google.com/reader/api/0/subscription/edit but I'm getting an error saying "POST requests require a Content-length header." This is using curl in PHP. I can log in and get a token, the next step is where I get the error. Here is my code:

$ch = curl_init();

$data = array('accountType' => 'GOOGLE', 'Email' => 'user@domain.com', 'Passwd' => 'password', 'source'=>'nameyourapp', 'service'=>'reader');

curl_setopt($ch, CURLOPT_URL, "https://www.google.com/accounts/ClientLogin"); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

$loginResult = curl_exec($ch);

$authRaw = strstr($loginResult, "Auth"); $authToken = substr($authRaw, 5); $header = 'Authorization: GoogleLogin?? auth='.$authToken;

curl_setopt($ch, CURLOPT_URL, "http://www.google.com/reader/api/0/token"); curl_setopt($ch, CURLOPT_POST, false); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$token = curl_exec($ch);

//everything works fine up to here

$data = array('s' => 'http://feeds.feedburner.com/TechCrunch', 'ac' => 'subscribe', 'a' => 'user/-/label/techcrunch', 'token'=> $token); $data = http_build_query($data); $header = 'Content-length: ' . strlen($data);

curl_setopt($ch, CURLOPT_URL, "http://www.google.com/reader/api/0/subscription/edit?client=contact:user@domain.com"); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

$result = curl_exec($ch); curl_close($ch);

print ($result);

As you can see, I am sending the content-length header. But the error makes it sound like it's not even there. I've searched Google and found other people having this error message with different Google services, but none of them seem to be able to resolve the issue. Some of them make it sound like it's a problem on Google's end. Please help!

and always getting error.

Please see my iphone code #define SUBSCRIBE_URL @"http://www.google.com/reader/api/0/subscription/quickadd?ck=%@&client=FeedViewer&quickadd=%@&ac=subscribe&token=%@" #define SUBSCRIBE_URL_VALUE @"feed%2Fhttp://feeds.feedburner.com/TechCrunch?" pStrToken?= nCt3Vgbs0Xgj7Jx_jNpWvQ ;

Please suggest if I am doing any thing wrong.

Following this http://code.google.com/apis/accounts/docs/OAuth2.html I managed to get an OAuth2 access_token, but I can't make use of it... Keep returning Status=Unauthorized - 401

To use the OAuth flow u can try to set the scope? param:

• http://www.google.com/reader/api/0/
• http://www.google.com/reader/atom/

Example:

https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=<your_client_id>&redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&scope=https%3A%2F%2Fwww.google.com%2Freader%2Fapi%2F0%2F

If anybody figure this out, please share it :D

I have forked a fork of this class here ;) https://github.com/brutuscat/googlereader. It currently works so try it :D

Is there a way to get a feed of your starred news items, BUT only for a certain folder or tag (or even feed).

My idea is to put this rss feed into Boxee so I see only my starred YouTube? Subscription video, and not all of them like at the moment. http://gdata.youtube.com/feeds/base/users/USERNAME/newsubscriptionvideos

http://googlesystem.blogspot.com/2009/05/feed-for-youtube-subscriptions.html

Does kept-unread mean the box was specifically only checked marked and tracking-kept-unread will be a superset of kept-unread?

Here is a class I have developed, in order to use this Google Reader API in JAVA : http://lewebenbien.wordpress.com/2011/06/06/google-reader-api/ Hope that could be useful for someone else :)

hello i want to add smart feed adding to my program, so i need the api url to retreive a feed list maching a keyword (in browser the page is http://www.google.fr/reader/view/?#directory-search/<MY_KEYWORD>//0 ) thanks a lot PS :the page can retreive multiple times the same url in results but i want only one time each (maybe an additional parameter). i want results as a list of subscriptions : - string:title - string:url - int:nbsuscribers - float:nbnewsbyweek - bool:suscribed (no mandatory, since i can compute it myself)

HI , please one question. I want to get 999 atoms for one particular user. It works like http://www.google.com/reader/atom/user%2F14750707885618507930%2Fstate%2Fcom.google%2Freading-list but here I onle get 20 items. How can I get 999 Items? Thanks

You should use parameter n (count).

Hello everyone. Need help. I try to set a star for feed.

I use these params as post args: key = i, value =tag:google.com,2005:reader/item/88a3ce8e14832f39

key = T, value =eMMPqk1Ls1gA6EIi5ml0nw

key = async, value =true

key = a, value =user/-/state/com.google/starred

key = ac, value =edit-tags

These params I use for header args:

key = client, value =googlereader-ios-client

key = ck, value =1322744198

In reply I get html with an error "There was an error in your request.". The same error occurs when I try to mark a feed as read, favourite and others.

Does Google Alert (via ATOM Feed) include social mentions (in FB, TW, G+) ?

What does "published" and "updated" fields mean? Is it a date ? If it is date then explain what does "1325880983" mean as date ?

@Valeh: They are UNIX timestamps. See http://en.wikipedia.org/wiki/Unix_time. 1325880983 corresponds to Fri, 06 Jan 2012 20:16:23 GMT.
