New fields for MassPay
March 26th, 2025
Merchants using FlexPay alongside the payment orchestrator MassPay now have additional fields available.
Merchants can send customer_id as a gateway-specific field, which represents a reference number for the customer within MassPay. Note that using this value will overwrite thecustomer_reference_id when sending the payload to MassPay.
Furthermore, processor_id_external is now passed back to the merchant as a gateway specific response field. This represents the transaction ID created by the external processor.
