What is an API?
Otherwise known as Application Programming Interface, an API is a set of code features which are pre-written, in order to maintain best practice, and write consistent code. API is a software which allows two applications to communicate - access data, and interact with external software components and operating systems.
An API tool set assists programmers to create software. An example of an API in action is an instant message sent via the Facebook app.
APIs enable developers to make repetitive yet complex processes highly reusable with a little bit of code. The speed that APIs enable developers to build out apps is crucial to the current pace of application development. With an API, the wheel does not need to be reinvented every time a new programme is written.
Instead, the focus can be on the unique proposition of their applications while outsourcing all of the commodity functionality to APIs.
