GETGet Sender Profile

Fetch the DMT-Fino profile of a registered sender by mobile number.

GET/customer/payment/dmt-fino/sender/{customer_id}

The first step in the DMT flow. Call this to check whether a customer is already registered as a DMT sender. If the sender exists, the response returns their profile and remaining transfer limits so you can skip registration.

Tip

This endpoint is one step in a complete workflow:

DMT (Fino) — Send Money — Full Fino DMT money-transfer flow: look up the sender, onboard and biometric-eKYC them if new, pick or add the recipient, then send an OTP-verified transfer.
