Faster payments

Confirmation of payee [beta]

Verify a beneficiary's account name before making an FPS payment using the Confirmation of Payee (CoP) service.

CoP allows payers to check that the name they have for the intended recipient matches the actual name on the recipient's account, reducing the risk of fraud and misdirected payments.

This verification does not create an FPS payment transaction. The request is forwarded to the payment provider for real-time name verification.

This endpoint generates a CoP name verification requested event. The result is received in a CoP name verification result received event.
