What can you do with the REST API in WordPress?
In particular, the WordPress REST API enables you to connect your WordPress website with external applications. This means you can develop a mobile app using practically any programming language, and use the WP REST API to fetch data from WordPress.
Why do I need to call an API in WordPress plugin?
One of the great things about WordPress is the plugins available for download. They are all designed with the intent of expanding the capability of the site.

How are request headers used in the REST API?
Request headers do not necessarily interact with our endpoints directly, but the information in the headers helps WordPress know what to do. To pass in data that we want our endpoints to interact with we want to use parameters. When making requests to the WordPress REST API, most of the additional data passed in will take on the form of parameters.
How does the WP _ REST _ server class work?

You can use these functions to add fields to any of the object types supported by the REST API.
What does a route mean in the REST API?
