A software interface called a bank data API allows applications to access and obtain financial data from a bank's database. It allows programmers to connect to the bank's data and build applications that can access and look at financial data, such as account balances, transaction histories, and other financial data.
The use of banks API has become increasingly important as more banking services migrate online and data becomes more widely available. By utilizing bank data APIs, developers can produce software that offers customers more specialized financial services like budgeting and saving tools, investment analysis, and loan services.
Bank data APIs come in a variety of forms, including open banking APIs and private bank APIs. Open banking APIs are created by third-party providers who collaborate with various banks and are intended to be more easily available. On the other hand, proprietary bank APIs are created and maintained by certain banks and may have fewer functionalities.
