Paypal定期付款IPN

Question

I set up an IPN inside Paypal to hit every time a Recurring Payment using Payflow Pro is set to go through. How can I make it send back the variable for the custom ID I need to make sure that I can use to extend the membership?

So far I have tried ProfileID, payer_business_name, option_name1, rp_invoice_id, invoice, and custom, none are sent back when it goes through.

Answer 1

The custom variable should certainly work, if it was included in the POST. Alternatively you can add any variable name=value pair you like to the notify_url, as long as they don't conflict with PayPal's IPN variables.

Answer 2

rp_invoice_id is returned in both recurring_payments_profile_created and regular recurring_payment IPN's. Here's a sample of both.

If you're not getting rp_invoice_id in your IPN's then it must not be getting included in your API request correctly.
