How do bank APIs work?
Banks use APIs to learn information about their customers that helps them offer more personalized services, such as offering a loan or savings product that might make sense for an individual customer.
Banks use APIs to solve several issues. They might use APIs for account authentication and for payment processing. Banks also use APIs to allow third-party applications to access the bank's financial information and customer accounts. This is an efficient way for banks and third parties to partner on innovative products that better serve customer needs.
Through the use of APIs, banks learn information about their customers that helps them offer more personalized services, such as offering a loan or savings product that might make sense for an individual customer.
A good API also can give consumers a more seamless banking experience. APIs are part of the technology that allows customers to use their apps to make payments and keep track of their finances wherever they are.
A bank might use a private API that can only be used by the bank's staffers to improve internal operations. This type of API is the most private and secure, but it prevents the types of partnerships that often lead to innovation.
Other banks might use a partner API that only certain third-party partners can use. This is a sort of 'middle ground' that allows banks to work with specific partners while keeping others out.
Finally, some banks might choose to employ an open API that can be used by anyone. While this opens almost unlimited opportunities for innovation, it also opens the API to more security risks.
Large banks can use APIs to forge new partnerships with emerging fintech leaders. APIs also can be a boon to smaller banks. A small bank might not have the staffing, funding or technology to provide cutting-edge service to customers. By making use of APIs, these smaller banks can partner with companies and tap into more robust functionality.
