WordPress Integration with API

API, also known as “Application Programming Interface”, has changed the way we use the internet, develop codes and software, and interact with other programs, applications, and software.

There are more than 24000 APIs registered online with 2 Million+ API repositories on GitHub. All of the technological connection and communication is pretty much driven through CMS or WordPress API integration; which is user-friendly, and flexible to use.

90% of developers use any kind of APIs, among which:

  • 69% use third party APIs
  • 20% use internal APIs

A WordPress REST API allows you to connect your WordPress website with any other external software or application for using any features, functionalities or connect with another framework fetching WordPress data.

In simpler words, API connects and lets the applications or software communicate with one another without intervention in one another’s system.

How Does API Work?

Wondering how API works, let’s understand it through a real life example.

For instance, there is an Airline company who sells its tickets first hand. Another third-party service provider (Company1) proposes to sell and book that Airline’s tickets through them. The airline company will not disclose its personal data or credentials to Company1 to make changes in its system due to security and confidentiality reasons (which is, anyhow, irrelevant to Company1), but it will provide an API key to Company1. Company1, using the WordPress API key, requests to access the airline’s web server and after authentication, books their tickets taking out their own commission.

The API key will become the endpoint of Company1 to proceed with the airline company and the rest will be handled by the airline company itself.

When to Use the WordPress REST API?

Before even knowing WordPress REST API, you are using one; for example your credentials to log into your instagram or facebook account are automatically filled in the login form. It is a REST API!

If you intend to write a plugin or theme or other external application as JavaScript application or standalone program in any other programming language besides PHP, use WordPress REST API to access content with WordPress site.

  • For Better Performance

Developers create edge-cutting features without using a lot of server-side resources with the help of WordPress REST API. Features developed with the help of WordPress API are much faster, user-friendly and responsive than using PHP.
