Yes, I could not agree more on spotty quality. The paypal instructions are below. See # 3.
I'm checking out urllib2 now. I don't see a way of obtaining a response. Co n s t r u c t i n g Yo u r P o s tb a c k Use these guidelines for constructing your postback to PayPal:. 1. Your postback must be sent to https://www.paypal.com/cgi-bin/webscr. Instant Payment Notification (IPN) Using IPN with Multiple Currencies 3 28 March 2008 - first technical draft Order Management Integration Guide NO T E: You can implement IPN without SSL, including your postbacks for validation, but PayPal recommends against doing so. 2. Your postback must include the variable cmd with the value _notify-validate: cmd=_notify-validate 3. Your postback must include exactly the same variables and values that you receive in the IPN from PayPal, and they must be in the same order. P r o ce s s i n g t h e P a y P a l Re s p o n s e t o Yo u r P o s t b a c k *PayPal responds to your postbacks with a single word in the body of the response: VERIFIED* *or INVALID.* When you receive a VERIFIED postback response, perform the following checks on data in the IPN: 1. Check that the payment_status is Completed. 2. If the payment_status is Completed, check the txn_id against the previous PayPal transaction that you processed to ensure it is not a duplicate. 3. Check that the receiver_email is an email address registered in your PayPal account. 4. Check that the price, carried in mc_gross, and the currency, carried in mc_currency, are correct for the item, carried in item_name or item_number.
