FAQS

Everything You Need to Know About API Banking

What is API Banking?

API Banking allows banks and third-party applications to communicate securely using Application Programming Interfaces (APIs). It enables businesses to integrate banking services—like payments, balance checks, and account management—directly into their own systems and apps.

How does API Banking work?

API Banking works through secure connections between a bank’s backend systems and third-party platforms. APIs expose specific banking functionalities such as fund transfers or account details. When a request is made via the API, the bank processes it and sends back a real-time response in a standardized format, usually JSON or XML.

What are the benefits of API Banking for businesses?

Businesses benefit from faster transactions, automated reconciliations, and real-time data access. It reduces manual intervention, improves operational efficiency, and enhances customer experience by integrating banking directly into business workflows or ERP systems.

Is API Banking secure?

Yes, API Banking uses advanced encryption, authentication mechanisms, and secure tokens to ensure that only authorized systems can access banking data. Banks follow strict compliance protocols such as OAuth 2.0, SSL/TLS, and audit trails to maintain security and integrity.

What are some examples of API Banking services?

Common API Banking services include Account Balance Inquiry, Fund Transfers (NEFT, RTGS, IMPS, UPI), Virtual Account Creation, Transaction Statements, Collections and Payout APIs, and Payment Gateway Integrations. These services simplify how businesses handle financial operations.

How can a company start using API Banking?

Companies can start by partnering with a bank that provides open banking APIs or with fintech providers offering API platforms. After integration and testing in a sandbox environment, APIs can be securely deployed in production to enable real-time banking services within the company’s systems.
