Complete Guide to AEPS API Integration for Businesses and Retailers

By Ankit Vijay February 10, 2026 AEPS 0 Comments

In today’s digital payment era, AEPS API Integration has become one of the most powerful tools for businesses and retailers to offer banking and financial services directly to their customers. With AEPS (Aadhaar Enabled Payment System), retailers can provide secure and instant cash withdrawals, balance inquiries, and fund transfers using just an Aadhaar number and fingerprint authentication. This system not only supports financial inclusion but also helps businesses grow by expanding their service portfolio.

AEPS (Aadhaar Enabled Payment System) API integration allows businesses to embed basic banking services, such as cash withdrawals and balance inquiries, into their own applications or platforms. This is achieved by using a software tool, an API, that connects a business’s system to the AEPS infrastructure, enabling customers to conduct transactions using their Aadhaar number and biometric authentication. The process involves a business choosing a provider, integrating the provided API or SDK into their platform, and then initiating transactions for customers.

Partnering with a trusted AEPS API provider like Noble Web Studio ensures seamless integration, strong security, and real-time transactions. Their advanced AEPS software solutions are designed for retailers, distributors, and B2B businesses who want to enter the digital banking ecosystem with ease. Through AEPS API integration, businesses can boost customer trust, generate more revenue, and become a part of India’s fast-growing digital finance network.

If you are looking to upgrade your business with digital payment services, this complete guide by Noble Web Studio will help you understand everything about AEPS API integration, its benefits, working process, and how it can transform your retail business into a digital payment hub.

What is AEPS API Integration

AEPS API integration allows businesses to embed Aadhaar-based banking services (cash withdrawal, balance inquiry, etc.) into their applications. The process involves partnering with a certified service provider, meeting legal and technical requirements, and integrating their API into your platform.

AEPS API Integration Work

AEPS (Aadhaar Enabled Payment System) API integration work involves embedding Aadhaar-based banking services into a business’s application or platform. This process allows customers to perform basic financial transactions using their Aadhaar number and biometric authentication (typically fingerprint or iris scan), effectively transforming a merchant’s location into a micro ATM.

AEPS (Aadhaar Enabled Payment System) API integration allows businesses to offer basic banking services through their own applications or platforms using a customer’s Aadhaar number and biometric authentication. This integration connects the business’s system to the AEPS network, facilitated by the National Payments Corporation of India (NPCI), and then to the customer’s bank.

Here’s how AEPS API integration typically works:

Customer Interaction: A customer initiates a transaction (e.g., cash withdrawal, balance inquiry) at an AEPS-enabled point, such as a merchant’s store equipped with a biometric device and the integrated application. The customer provides their Aadhaar number and the desired banking service.
Biometric Authentication: The merchant uses a certified biometric device (fingerprint scanner or iris scanner) to capture the customer’s biometric data for verification.
API Request: The merchant’s application, integrated with the AEPS API, sends a request containing the customer’s Aadhaar number, bank name (IIN), transaction details, and the encrypted biometric data to the AEPS network via the API provider.
Network Routing and Verification: The request travels through the AEPS network to NPCI’s platform and then to the customer’s bank. The bank verifies the Aadhaar number and biometric data against records at the Unique Identification Authority of India (UIDAI).
Transaction Processing: Upon successful verification, the customer’s bank processes the requested transaction.
Confirmation and Response: The bank sends a transaction status back through the AEPS network and the API provider to the merchant’s application. The merchant then provides a confirmation or receipt to the customer and completes the service, such as dispensing cash for a withdrawal.

Top Use Cases of AEPS API Integration

The top use cases for AEPS API integration include basic banking services like cash withdrawal, deposit, and balance inquiry in rural areas, disbursement of government benefits, and Aadhaar-to-Aadhaar fund transfers. This integration allows businesses, particularly retailers, to offer financial services via micro-ATMs or apps, increasing foot traffic and earning commissions, while promoting financial inclusion for customers.
