WP REST API Filter Items

A WordPress plugin to filters WordPress REST API items for your request. Its removing key and values from WP API response on your request.

Description

Per default, a post via WordPress REST API would fetch all data in wp-json/wp/v2/posts. For many reasons, you might want to exclude certain fields from WP API response in certain circumstances. This plugin enables you to filter your request for fields you require. Add items to the GET attribute on the url, like wp-json/wp/v2/posts?items=id,title,content in order to get only according field values.

The plugin currently supports the filtering of post, taxonomy and comments.
