As you can see, there is field called rp_invoice_id which is The merchant’s own unique reference or invoice number, which can be used to uniquely identify a profile.

When creating API call CreateRecurringPaymentsProfile, how to pass this value, which field should I set in the API call?

Thank you

Answer 1

You need to use the PROFILEREFERENCE parameter to pass in a value that will be returned via IPN in the rp_invoice_id parameter.

PROFILEREFERENCE

(Optional) The merchant's own unique reference or invoice number.
