Open banking refers to the practice of providing access to the bank customers’ financial data to third-party financial service providers with the help of APIs.

Traditionally, only you and the bank could access the financial data, but with open banking, third-party services can also use some of that financial data and implement new features in their applications to improve user experience.

How Does Open Banking Work?

Open banking works by securely exposing a customer’s financial data to a third-party service, such as a payment application or a financial analysis tool.


With the help of open banking, you can make payments, receive rewards and analyze your transactions using third-party applications.

There are some variations in open banking across the globe. In some parts of the world, it’s regulated; in others, it’s industry-driven.

The best example of open banking is the UPI (Unified Payments Interface) service in India. It allows users to manage multiple bank accounts on a single mobile application and also make real-time instant transactions.

What’s an Open Banking API?

An open banking API is a secure channel through which banks and other financial institutions can share customer data with third-party service providers. It’s a gateway for the seamless transfer of data without compromising security.

Benefits of Open Banking API

There’s not just one single beneficiary of open banking APIs. It benefits customers, banks, financial institutions, and businesses collectively.

Here are some of the benefits of open banking APIs:

  • Personalization: It is useful for businesses because they can convert the data about the customers into a personalized experience.
  • Customer Experience: Consumers are benefitted from this because of innovation and competition to create better services.
  • Higher Conversion Rate: Personalization and great customer experience lead to higher business conversion rates.
  • Personal Finance: Users can make informed decisions and spend wisely using various financial tools provided by third-party services.
  • Reduced Service Cost: Customers benefit from this because of competition in the market.
  • Security: The data is transferred securely between a financial service provider and the data holder using robust APIs.
