Now you have no need to make additional requests to get taxonomy info (term_id, name, slug, term_group, term_taxonomy_id, taxonomy, description, parent, count, filter) from their id that is available in the default json response.

Now all available taxonomy data is available in 'pure_taxonomies' field from your json response. It works for all custom added taxonomies, and for custom post types.

For example in 'wp-json/wp/v2/posts' you can find default fields 'categories', 'tags' and name of custom added taxonomies that contain only its id. With this plugin you can also find new 'pure_taxonomies' field that include all available 'categories', 'tags' and custom taxonomies data.

Before: { ... categories: [ 3 ], tags: [ 2 ], custom_taxonomy_name: [ 1 ] ... }

After: { ... pure_taxonomies: { categories: [ { term_id: 3, name: "First category", slug: "first-category", term_group: 0, term_taxonomy_id: 3, taxonomy: "category", description: "", parent: 0, count: 3, filter: "raw", cat_ID: 3, category_count: 3, category_description: "", cat_name: "First category", category_nicename: "first-category", category_parent: 0 } ], tags: [ { term_id: 2, name: "First tag", slug: "first-tag", term_group: 0, term_taxonomy_id: 2, taxonomy: "post_tag", description: "", parent: 0, count: 2, filter: "raw" } ], custom_taxonomy_name: [ { term_id: 1, name: "Custom Taxonomy Name", slug: "custom-taxonomy-name", term_group: 0, term_taxonomy_id: 1, taxonomy: "custom_taxonomy_name", description: "", parent: 0, count: 1, filter: "raw" } ] } ... }

How to add custom taxonomies into Rest API:

/**
 * Add REST API support to an already registered taxonomy.
 */
    add_action( 'init', 'my_custom_taxonomy_rest_support', 25 );
    function my_custom_taxonomy_rest_support() {
        global $wp_taxonomies;

        //Here should be a list of names of the already created custom taxonomies:
        $taxonomy_names = array(
            'clients',
            'technologies'
        );
        foreach ( $taxonomy_names as $key => $taxonomy_name ) {
            if (isset($wp_taxonomies[$taxonomy_name])) {
                $wp_taxonomies[$taxonomy_name]->show_in_rest = true;
                $wp_taxonomies[$taxonomy_name]->rest_base = $taxonomy_name;
                $wp_taxonomies[$taxonomy_name]->rest_controller_class = 'WP_REST_Terms_Controller';
            }
        }
    }

        global $wp_post_types;

        //Here should be a name of your already created custom post type:
        $post_type_name = 'portfolio';
        if( isset( $wp_post_types[ $post_type_name ] ) ) {
            $wp_post_types[$post_type_name]->show_in_rest = true;
            $wp_post_types[$post_type_name]->rest_base = $post_type_name;
