Hi, whenever I call the 2 functions, add\_user\_to\_discourse\_group and remove\_user\_from\_discourse\_group :

```
$user = get_user_by('id', $data["member_id"]);
error_log("Call add_user_to_discourse");
$result = DiscourseUtilities::add_user_to_discourse_group($user->ID, $discourse_group);
error_log(print_r($result, true));

```

I get these error messages :

```
[02-May-2020 17:32:23 UTC] Call remove_user_from_discourse_group
[02-May-2020 17:32:24 UTC] WP_Error Object

(
    [errors] => Array
        (
            [wpdc_response_error] => Array
                (
                    [0] => An error was returned from Discourse while trying to sync the sso record.
                )

        )

    [error_data] => Array
        (
        )

)

```

Could you help me please ? 🙂

It seems likely that this is an authentication error. On the [WP Discourse](https://github.com/discourse/wp-discourse) Connection Options tab, make sure that you are using an All Users Discourse API Key and your site’s system user for the Publishing Username (this defaults to `system`.)
