What is API?

Application Programming Interface (API) is a set of certain tools, specific standards, and protocols, which a programmer uses to integrate various applications. APIs allow access to another platform or app. Using APIs, applications can interact with one another. Plus, the use of APIs doesn’t just simplify programming, but also improves user experience, facilitating the control of users over an array of applications and increasing your application’s popularity. Today, specialized APIs are improving every advanced application.

There are many types of APIs, differing based on what programming language is used for applications — for a software library; for computer hardware; for a database system; for operating systems (Microsoft Windows API, POSIX is for Linux and Berkeley Software Distribution); for a website or a web-based system (eBay, Amazon); for applications (LinkedIn API, Twitter APIs, Facebook API, Google Maps API).

In addition, there are three fundamental policies for releasing APIs: public (for public use), partner (for business partnerships), and private (for internal use).

As for the design of an API, it aims at offering only those tools that end users expect. Here, the principle of information hiding is used — not bothering users with unnecessary information that they don’t want.

Each API goes with documentation where every bit of information on how to use the API and what services it offers is given. API documentation is also essential for developers because it comprises code snippets, typical usage scenarios, descriptions of methods and classes, etc.

The benefits of using APIs

  • Push files and retrieve data by integrating mobile apps with a remote backend
  • Integrate web/mobile apps with cloud storage of files
  • Empower your CRM apps or lead generation with social insights (by matching email addresses against social media profiles.)
  • Get real-time functionality and an ability to manage computations without needing to write your own intricate algorithms (this is especially useful for companies operating in the finance and e-commerce sector)
