Integrators are able to retry a "PAST_DUE" invoice using the retry payment API. Once the retry payment is actioned, the status of the invoice will return to "PROCESSING".
The retry payment API will validate if the paymentMethodToken is still a valid token before allowing the retry payment to proceed. If the paymentMethodToken used is an invalid token, integrators are required to replace the paymentMethodToken for the "PAST_DUE" invoice.
It is important to note that integrators are required to manage the MAX retry on their application.
