Hi there,

One thing to check is make sure you have a valid attendee ID. You can go to Event Espresso > Registrations > Contact List, then check what’s listed there to see if there’s an ID that matches the attendee ID.

The other thing to check is whether the request was authenticated. Other routes like
/wp-json/ee/v4.8.36/attendees
and
/wp-json/ee/v4.8.36/registrations
with no additional params also require authentication, whereas requests to routes like these:
/wp-json/ee/v4.8.36/events
and
/wp-json/ee/v4.8.36/venues
do not require authentication.

Let’s step back a bit because you don’t actually get events or registrations from a request to /wp-json/ee/v4.8.36/attendees, that particular route returns a list of attendees.

The route that lists registrations is:
/wp-json/ee/v4.8.36/registrations
and you can get the name of the associated event with each registration.

If you only have the User ID, to get a list of registrations for the user, you’ll have to do two API endpoint queries:
The first query to usermeta using the WP rest api to get the Attendee ID, and then the second with that Attendee ID to the EE REST API.

Another step back: WordPress does not expose meta to the REST API by default, so you’ll need to add a little function like this to your site’s functions plugin to expose the user meta field for Event Espresso’s Attendee ID:

add_action('rest_api_init', 'my_register_ee_attendee_id_meta');
function my_register_ee_attendee_id_meta() {
    global $wpdb;
    $args = array(
        'type'         => 'integer',
        'single'       => true, 
        'show_in_rest' => true
    );
    register_meta(
        'user', 
        $wpdb->prefix .'EE_Attendee_ID', 
        $args
    );
}

Once that’s ready, your first query will go like this:

/wp-json/wp/v2/users/{user_id}?_fields=meta

which will include the EE_Attendee_ID in the response. Then in the second query do this:

/wp-json/ee/v4.8.36/registrations?where[Attendee.ATT_ID]={EE_Attendee_ID}&include=Event.EVT_name
