The information required to track a payment depends on the payment method used:

• Domestic wires: You will need the IMAD (Input Message Accountability Data) or OMAD (Output Message Accountability Data) reference. These unique identifiers are assigned to wire transfers within the U.S. financial system and help banks locate transactions in their system.
• SWIFT payments: You will need the MT103 document, which serves as proof of payment in international wire transfers. This message contains details such as sender and beneficiary information, transaction reference, and timestamps.
