Website Api

My website is [login to view URL] I am trying to implement the Unlockbase API in a form on the first page which has few fields; The Make, Model, Carrier, Email and IMEI. I have everything implemented but it does not seem to be working for some reason (once the customer pays, the information is not passed to the Unlockbase API instead I get an error, it could be SSL related or something in the paypal IPN or a different bug not sure) I attached a copy of the API documentation so you can look at it and understand how the API works I need the fix to be done in the next 12 hours
