Google Checkout ASP Sample Code

The OrderProcessingDemo.asp page demonstrates a simple implementation of a page that sends Order Processing API requests to Google Checkout.

To adapt the OrderProcessingDemo.asp implementation for use in your site, you will need to be able to retrieve the Google Checkout order number associated with an order. You will also need to be able to retrieve information about the order's status (archived, active, canceled, etc.), the amount you have charged the customer for the order, and shipment tracking information for the order. You will then need to call the appropriate OrderProcessingAPIFunctions.php functions, as demonstrated in the sample implementation, to execute the appropriate order processing commands.

In addition, partners who are implementing the Order Processing API also need to implement the Notification API to process and store order data received from Google Checkout.

' The following HTML page calls the displayDiagnoseResponse function,
' which is defined in GlobalAPIFunctions.asp, to verify that the
' API request contains valid XML. If the request does contain valid XML,
' the page sends the request to Google Checkout by calling the sendRequest
' function, which is also defined in GlobalAPIFunctions.asp.
' The page then calls the processXmlData function, which is defined in
' ResponseHandlerAPIFunctions.asp, to handle Google Checkout's API response.
'
' If the request does not contain valid XML, you will see a link to
' a tool that lets you edit and recheck the XML. The code for that
' tool is in the <b>DebuggingTool.asp</b> file, which is also
' included in the <b>checkout-asp-samplecode.zip</b> file.
