What Is a Real-Time AEPS API?

A real time AEPS API is a software link that lets apps process instant bank tasks like cash withdrawals and balance checks using an Aadhaar number and a fingerprint scan. It connects local shops to the national banking system without needing a debit card or a PIN. 

How Real-Time AEPS API Works (Step-by-Step)

A real-time AePS API works by connecting a merchant or Aeps banking app through encrypted channels to the NPCI switch, validating a user’s 12-digit Aadhaar number and biometric fingerprint against the UIDAI database to instantly execute cash withdrawals, balance checks, or mini-statements. 

Transaction Workflow

• Initiation: The agent or retailer enters the customer’s 12-digit Aadhaar number, selects the bank name, and chooses the transaction type (such as cash withdrawal or balance check) on their best Aeps application. 
• Biometric Capture: A certified biometric scanner captures the customer’s fingerprint or iris scan and securely encrypts the data package. 
• Routing and Verification: The best real time Aeps API transmits this packet to the National Payments Corporation of India (NPCI) switch, which routes it to UIDAI for biometric matching and to the customer’s specific bank for ledger validation. 
• Settlement and Confirmation: Once approved by the core Aeps banking system, funds transfer or account details return via the top Aeps API in 2 to 3 seconds, triggering an instant digital confirmation receipt and wallet credit for the merchant.
