Posted 2021-05-05

<?php 
function add_cpt_to_rest() {
    global $wp_post_types;

	$rest_post_types = [POST_TYPE_NAME1, POST_TYPE_NAME2];
	
	foreach ($rest_post_types as $cpt_name) {
        $wp_post_types[$cpt_name]->show_in_rest = true;		
	}
}

add_action( 'init', 'add_cpt_to_rest' );

<?php 

add_action( 'rest_api_init', 'register_api_hook' );
function register_api_hook() {
		
	$rest_post_types = [POST_TYPE_NAME1, POST_TYPE_NAME2]; // the field is added for these post types in the API
		
    register_rest_field(
        $rest_post_types,
        'field_name_here',
        array(
            'get_callback'    => 'return_field_name_here',
        )
    );
}

function return_field_name_here( $post, $field_name, $request ) {
    // return for example user (author) meta based on the post object
    $author_id = $post['author'];
    $field_name = get_user_meta( $author_id, 'field_name', true );	
	
    return $field_name;
}

<?php
