Paypal subscription API - transaction variables not POSTed
- by morpheous
I am writing a payments system based around paypal, I am using the HTML 'API'.
I am passing the following form fields to PayPal:
'rm' = 2
'return = http://www.example.com/payment-handler.php?token=sometoken
Where 'token' is a token I generated.
According to the paypal documentation, a return method (rm) of 2 indicates to Paypal that the transaction data be posted back to the callback url using the POST method.
When processing items using 'buy_now' buttons, the transaction items are correctly POSTed to my callback url (payment-handler.php), but for 'subscribe' operations, although the callback url is called, no POST data is sent to the url, and also, the 'token' field is missing. Instead, there is a parameter called 'auth'.
I cant see anything in the paypal docs about a 'auth' field - so I dont know whats generating it and if I can reliably using it. Can anyone shed some light on this?
