Banking & Finance Verification APIs

UPI Verification API

Check that a UPI ID exists and get the account holder's name, with an optional name match.

What it verifies

Who uses it

Fintech and payments apps confirming a payout destination before sending money
Lenders and marketplaces verifying a UPI ID given for disbursals or refunds
Platforms that want to match a payee's name against the name on their UPI ID
