POSTAePS Mini Statement

Retrieve the last few transactions from an Aadhaar-linked bank account via biometric authentication.

POST/customer/collection/aeps-fingpay/mini-statement/{customer_id}

Fetches a mini statement (typically the last 5–10 transactions) from a customer's bank account by authenticating through Aadhaar biometrics. Uses the dedicated mini-statement endpoint — the request shape matches Balance Enquiry (no amount). No money movement occurs. The response includes a list of recent debit/credit transactions with amounts and dates. Useful for customers who want to verify recent activity at an agent point without visiting a branch.

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