WordPress REST API for Custom Posts

Prerequisite: REST API support needs to be added to custom posts while registering the custom post.

Below parameters add the necessary support. For detailed instruction please refer Adding REST API support to Custom Post Types

Suppose we have a Custom Post Type news, below parameters would add the necessary REST support to the Custom Post Type


This allows the Custom post type to be accessed through the REST API

rest_base => Optional Parameter

This allows to change the REST API route. For e.g. if the custom post type is news. We can define a custom route to access the books post using rest_base parameter e.g. news_api


This is only required to be changed if you are using a custom namespace i.e. other than wp/v2

Once the necessary support is added as shown above the Custom Post Type is ready to be accessed through the REST API
