Understanding open banking APIs

Open APIs are sets of rules and protocols that enable different software applications to communicate and exchange information with each other. In finance, these APIs are called open banking APIs.

They enable third-party developers to access a bank's data and services in a secure and controlled way. This can include checking account balances, making payments, or gathering financial information, all with the customer's permission.

Open banking APIs aim to foster innovation, improve customer experiences, and increase competition in the financial sector by providing more choices and better services
Open banking APIs facilitate two key functions:

Data sharing

They act as secure tunnels, allowing controlled access to specific data and services between institutions.  For example, when you apply for a loan online, an open banking API can securely send your financial details, like income and transactions, from your bank to the lender without needing manual paperwork. This makes the loan process quicker and easier.


They help third-party developers and companies to integrate various financial services seamlessly with their software. For instance, booking a flight online involves searching, selecting, and paying. Open banking APIs enable travel apps to integrate with payment gateways for secure transactions and even insurance providers for travel protection, all within a single app.
