Look up a payment
POST /payment-Lookup returns one payment that belongs to your merchant.
{ "merchantIdentifier": "6c63548f-f85d-4e85-a15f-9edd60e6c8dc", "referenceCode": "ORDER-2026-000123" }- If
paymentUuidis given it is used; otherwisereferenceCode. paymentUuidhere is the processor’s transaction id (thepaymentUuidof the create response), nottransactionUuid.- Some processors give no processor id (the FTD stand-in is one), so look those up by
referenceCode. - A payment owned by another merchant is reported exactly like a missing one:
404.
The response has transactionUuid, paymentUuid, type (DEPOSIT, REFUND or CHARGEBACK), status, amount,
currencyIso3, message and referenceCode. Remember that an in-flight payment is PENDING here and
IN PROGRESS in the create response.
