Hi. I guess all is in the title.

There is [https://meta.discourse.org/u/canapin.json](https://meta.discourse.org/u/canapin.json) but I don’t think there’s a route that uses the user id.

There is only one route that works with an id and no username that I know of. (which seems odd to me because usernames can change whereas ids can’t.)

Anyway, it’s a staff-only route, eg.

```plaintext
https://meta.discourse.org/admin/users/174238.json

```

If you are using SSO, there is the `/users/by-external/{$user_id}.json` route.

Is the discourse ID equal to the external ID?

No, the external\_id is the id that is provided in the SSO payload from the SSO provider site. If you are using the [WP Discourse](https://github.com/discourse/wp-discourse) plugin, there is a function that you can use for this:

```plaintext
WPDiscourse\Utilities\Utilities::get_discourse_user($user_id)

```

`$user_id` in the function call is the WordPress user\_id.
