POSTVerify Sender OTP

Verify the sender OTP to authenticate the PPI Levin wallet and return the sender's profile and balance.

POST/customer/payment/ppi-levin/sender/{customer_id}/otp/verify

Validates the OTP issued by Get Sender Information / Onboard Sender. For an existing sender the response returns the full wallet customer_profile (limits, balance, KYC state) and a wallet_token used by downstream calls. For a new customer the flow continues to Aadhaar validation (Aadhar Validation Pending) and then PAN (Pan Number Required).
