API (definition)

An application programming interface (API) is something that the developers of an application make to let other programs or applications talk to their application. When an application communicates with LoanPro via our API, rather than manually clicking ‘New Loan’ and typing everything in, your software will generate a little bundle of information with all the necessary loan specifics, and send it to a designated URL. LoanPro will receive that information at the URL, and use it to create a new loan. LoanPro will send back a response saying that your loan was successfully created. 

The purpose of this is so that programs written in different programming languages can communicate with each other and so that data can be safely sent and received from a proprietary application without having to give away access to the application’s code base.
