Get The OpenTM Transactional Application Programming Interface

APIs are mechanisms that enable two software components to communicate with each other using a set of definitions and protocols. For example, the weather bureau's software system contains daily weather data. The weather app on your phone “talks” to this system via APIs and shows you daily weather updates on your phone.

An API is also an abstraction of the web server. The application (such as a website or a mobile app) will make an API call for a set of data to display for the end user to consume. The request is made via the API that accesses the web server to retrieve the requested data, which is populated in the user interface.

The full form of API is the Application Programming Interface. API is a collection of protocols, routines and software-building apps. In essence, an API explicitly says how software elements should communicate. Furthermore, APIs are used while configuring GUI (graphical user interface) components.

API is the acronym for application programming interface — a software intermediary that allows two applications to talk to each other. APIs are an accessible way to extract and share data within and across organizations. APIs are all around us.
