Signing Up with Google Checkout

This section explains how to become a Google Checkout merchant and begin to integrate your online store.

1. Go to http://checkout.google.com/sell/signup to sign up for a Google Checkout merchant account. Complete the sign-up process and provide valid values for all fields. You will need the federal tax ID number for your business or a credit card and your Social Security number.

2. Sign in to your merchant account at https://checkout.google.com/sell/settings?section=Integration to locate your Merchant ID. You will need to insert your merchant ID in the code snippet on your web page that includes the Google Checkout shopping cart JavaScript file.

   
   
   

   Note: You should never share your Merchant Key with anyone, and no Google representative will ever ask you for your Merchant Key.

3. Under the Shopping cart post security header, uncheck the box to allow your account to use API requests with name-value pairs. After removing the check from the checkbox, click the Save button to save your settings.

   

   Note: This checkbox must be unchecked if you are going to use the Google Checkout shopping cart. Please note that this option indicates that the information in your shopping carts will not be digitally signed. As such, you will need to check orders to make sure they contain accurate information, including correct prices and shipping costs, before you ship items. You must use the XML API if you want to post digitally signed shopping carts.

4. After you have tested and customized your Google Checkout shopping cart, update your entire site so that the cart appears on every page where it's appropriate. Please make sure that you use your own Merchant ID when including the Google Checkout shopping cart JavaScript file on each page. You will receive an error if you try to process orders using the wrong Merchant ID.
