I need a google checkout subscription payment ipn script to be created in php. It must handle recurring billing, so I am able to create a google checkout subscription button, much in the same way as "paypal subscribe". I am selling digital products, so the script must be able to automatically check when a payment is successful and automatically update the database and send out an email to the client with sign-in credentials. The mySQL updates/password generation/email can be handled on our end as we already have the code in place. We will supply a sample of our database table so you are able to integrate with it, I would like to see how the query is structured, with sufficient comment in the code at each portion displaying whether it should be updating the DB for a new member, or renewing an existing members access on a successful rebill. You will need to get hold of the clients email address, Name and any google subscriptions ids associated with the transaction. I am currently operating on google checkout API v2 (though this setting can be changed) and has been set to post only digitally signed cart.
