I am trying to integrate a Google Checkout "Buy Now" button, and am hoping that there is some HTML code available similar to adding a Buy Now button in PayPal. I have not had much luck as yet, and was wondering if someone would be able to point me in the correct direction?
I also need to be able to add a callback address into the script (not set through the google checkout admin panel).
Thank you in advance for your help!
It's all documented in the Google Checkout API. Additionally, there is a guide that shows the different ways you can implement Google Checkout depending on your available resources.
