PUTDaily KYC

Perform the mandatory daily biometric re-verification that authorises an agent to carry out AePS transactions for the current calendar day.

PUT/user/collection/aeps-fingpay/kyc/biometric/daily

Biometric-only re-verification for the days after the one-time eKYC — no OTP step is required. AePS Fingpay requires every agent to re-authenticate themselves biometrically at the start of each working day, before their first transaction of the day.

If this fails with reason Please complete bank eKYC to process the transaction., re-run the full first-time eKYC sequence — Send OTP → Verify OTP → Biometric — before retrying.

To capture the piddata PID block with an RDService-compliant fingerprint scanner, see the Aadhaar Biometric Authentication guide.

Tip

This endpoint is one step in a complete workflow:

AePS (Fingpay) — Cash Withdrawal — Aadhaar-enabled cash withdrawal: one-time agent activation and eKYC, daily KYC, then the biometric withdrawal.
