I am trying to setup Google Checkout for recurring payments. amember has this short infor at the bottom of Google Checkout setup page: That does not really help. Can anyone shed more light on the steps required to set this up? Thanks.
This note is for notification callback url that you set in step 3 1. Your site must have valid SSL certificate signed by the CA from above list: http://checkout.google.com/support/sell/bin/answer.py?answer=57856&query=SSL 2. For testing account this is not necessary to use https url for notification callback. But for live account you must use https url.
