How do I identify orders with the Google Checkout Notification API (using PHP)? -


I am using the Google Checkout API for a simple store code. Where did I find the user to select the item, edit the cart, and make a checkout / payment with Google Checkout? After receiving the order, the notification API (with XML) is being used to read the information sent by Google. How can I connect order information with order information in my SQL database? Can I send "order id" or something like this to Google with the initial order? I have coded that part (ordering) with the HTML API.

Thank you in advance!

Use the merchant-private data field to pass any custom data about your order .

When you withdraw the notification, read the custom information from the merchant-private-data field.
