My aim is to customize users rest api : i would like to have a list of user social link users.

Is there a plugin i can use to : 1. to set the user social link ? 2. To get those links exposed by rest api ?

I've tried the following solution :

1.I upload a wordpress plugin to add some data. It's Simple Author plugin I am able to add some additional data to user ( social link list ) 2. I create a plugin to add this meta data be filled when i retrieved users from rest api. Here my plugin code :

 add_action( 'rest_api_init', 'adding_user_meta_rest' );

    function adding_user_meta_rest() {
       register_rest_field( 'user',
                            'collapsed_widgets',
                             array(
                               'get_callback'      => 'user_meta_callback',
                               'update_callback'   => null,
                               'schema'            => null,
                                )
                          );
    }


    function user_meta_callback( $user, $field_name, $request) {
       return get_user_meta( $user[ 'id' ], $field_name, true );
    }

I've tried a rest api get users request but i did not have the meta data listed in my response.

If you have an idea, i would like to know.

Thanks for your help.
