When the user is on the external app, they click a log-in button and get routed through Discourse’s SSO provider flow, and back to the external app. That external app can store a session with the user’s data. When the user logs out of Discourse, the webhook can delete the external app’s session. I’m not certain, but I think the webhook header is `X-Discourse-Event: user_logged_out`. **Edit:** logging out from the external site is done with the [Discourse API](https://docs.discourse.org/#tag/Users/paths/~1admin~1users~1%7Bid%7D~1log_out/post). Instead of asking Discourse whether a user is logged in, you can ask the external app. In my case it’s just for things like removing the log-in button in the external site. I can double check my code later. I haven’t looked at it in a while, but I think it did something like that. --- _[View the full topic](https://meta.discourse.org/t/is-there-an-endpoint-to-check-if-a-user-is-logged-in/72780)._
