WP-API JSON Feed

To provide a JSON feed for your custom post type, you need to specify an additional argument show_json_feed when registering the post type, and set it to a boolean true. You may optionally specify a json_feed_base argument being a string identifier that should be used in the feed URL. If no string identifier is provided, the post type slug will be used.

Here is an example, supporting a JSON feed for a custom post type “article” and setting its feed base to “articles” so that the feed will appear at {restURL}/feed/v1/articles.

<?php

add_filter(
    'register_post_type_args',
    function ( $args, $post_type ) {
        if ( 'article' === $post_type ) {
            $args['show_json_feed'] = true;
            $args['json_feed_base'] = 'articles';
        }
        return $args;
    },
    10,
    2
);

Since the JSON feed schema is always future compatible, by default the plugin preserves backward compatibility with older JSON feed readers by maintaining deprecated fields such as author. You can skip this backward compatibility behavior by using the wp_api_json_feed_skip_backward_compatibility filter and returning true.
