## Code

```php
// Post type => REST base (the URL part after /wp-json/wp/v2/).
$wpide_rest_types = array(
    'portfolio' => 'portfolio',
);

add_filter( 'register_post_type_args', function ( $args, $post_type ) use ( $wpide_rest_types ) {
    if ( isset( $wpide_rest_types[ $post_type ] ) ) {
        $args['show_in_rest'] = true;
        $args['rest_base']    = $wpide_rest_types[ $post_type ];
    }

    return $args;
}, 10, 2 );
```

## Notes

The post type also needs editor support for the block editor to appear. Test the plugin's own meta boxes, which may not all work in the block editor.
