I have encountered a problem with Paypal recurring payments.
CreateRecurringPaymentsProfile() returns ID of created profile (ProfileID). At the same time, I receive the following confirmation on IPN url:
payment_cycle - Daily
txn_type - recurring_payment_profile_
created
last_name - User
next_payment_date - 03:00:00 Oct 06, 2011 PDT
residence_country - US
initial_payment_amount - 0.00
currency_code - USD

Obviously, ProfileID and recurring_payment_id are equal. After this, a confirmation about the payment is received:
mc_gross - 20.00
outstanding_balance - 0.00
period_type - Regular
next_payment_date - 03:00:00 Oct 07, 2011 PDT

These 3 values: ProfileID in return of CreateRecurringPaymentsProfile(); recurring_payment_id in recurring_payment_profile_created; recurring_payment_id in recurring_payment – should be the same. (as it seems that there’s no other way to properly identify the payment for this specific subscription)
Also, recurring_payment (on IPN) is being sent by Paypal multiple times and every time recurring_payment_id is different.
Should I use recurring_payment_id to identify the payment for specific subscription or there’s another properly way to identify it?
Profile ID = recurring_payment_id. If recurring_payment_id is different, we’re talking about a different ProfileID (in other words: a different recurring payment profile).
