/users/by-external/ not working

This route doesn’t seem to be working:


It’s essential when using Disocurse as an SSO provider since you need to know the usernames of a user, given their external_id. (And since usernames can change, I don’t want to manage storing them in my own database).

Any idea how to make it work? I tried appending .json with no luck.

What does “doesn’t seem to be working” mean? Anything in the logs?

Just shows an “Oops! That page doesn’t exist or is private.”.

Even on this site, my user id is 26582 (got it by GET meta.discourse.org/users/biarity.json under user:id).
Performing GET meta.discourse.org/users/by-external/26582 shows Oops! That page doesn’t exist or is private.

Are you passing a valid API key? What do the logs say about the exact reason for the auth failure?

The external_id for a user doesn’t exist on Discourse until you send it with the SSO parameters from the site that is acting as the SSO provider. This site doesn’t use SSO, so it won’t work here.

Once a user has an external_id you can get the user by making a GET request to example.com/users/by-external/:external_id.json.


I’m doing the same request on my self-hosted discourse site (which is set up as an SSO provider), and still getting the same Oops! That page doesn’t exist or is private error. I’m using the external_id that’s been provided by discourse during SSO.

In my site, doing ( my external_id is 1):
GET http://[MY DISCOURSE SITE]/users/by-external/1.json?api_key=[MY API KEY]&api_username=[MY API USER] still yields a 404.

There’s nothing new in the error logs.

Is your external_id 1, or is your user_id 1? Can you show a dump of your single_sign_on_records table? Also, external_id is all about using another site as the SSO provider; if you’re using Discourse as the SSO provider, as you stated, you don’t need external_id because you’d use the user_id from Discourse to lookup the user.


Seems I was confused by the term external_id since it was included in the data sent by discourse during SSO. Apparently it’s supposed to be external to me, not to discourse (which makes sense now).

Calling GET /admin/users/:user-id (where user-id is the external-id given by discourse earlier) works well.

On a side note, is there a way of doing this without having to supply the API key? That would make integration with my client easier.
