I am trying to find someone that might be able to mod a few paypal IPN files so as they work with Google Checkout. Is this possible or is the system totally different? The program I have supports both 2Checkout.com and Paypal for payment processing, and I was hoping to get either one of them changed to work with Google. Price and timeframe please. Sorry, the system also supports Authorize.net as well. So we would have those files to start with for re-editing to change to work with Google.
You will need someone to write a completely different script for GCO. Unfortunately it is completely different even than the paypal web services API. Definitely get someone that has some good experiences with API's and web services, because the GCO API is complicated and is a pain to mess with.
