Counterparty Validation

This section explains how to validate external counterparty information before initiating outbound payments.

Before you initiate outbound payments we strongly recommend to use this API to check validity of the counterparty values. Our platform applies necessary checks as per respective regulations including Pay.UK Confirmation of Payee, Vocalink Modulus Validation or similar checks for IBANs.

Please contact to your account manager for more information about expected UX journey for Pay.UK CoP and error handling approaches.
