What is an API/Application Program Interface?
An Application Program Interface (known as an API) opens up access to a limited part of a piece of software so that other developers can take advantage of it.
By letting developers access an API for a particular application, the creator of the API helps other developers extend the functionality of their app, or provide information that was previously inaccessible.
Why Are APIs Important?
APIs are helpful in three main ways. First, APIs help developers to add new features to their apps and their software easily. Rather than building something from scratch, a developer can access a useful API to both save them development time and ensure that key functionality works effectively.
Second, creating an API helps the company behind it to expand in a natural manner. By giving external developers limited access to internal tools under strict conditions, API creators can increase the reach of their software and brand – providing them value for sharing their work.
Third, APIs help stitch the internet and mobile app economy together on behalf of users. They underpin essential online behaviors – such as sharing buttons or social login options. Even using mapping data in eCommerce apps requires an API, and as such APIs have become essential to users.
By using APIs, developers help reduce fragmentation across the internet and improve navigation through an interconnected ecosystem of sites, platforms and mobile apps.
