Thanks but no, I want any user viewing a profile on my main site, to be able to click a link on that page to take them to the corresponding profile on the discourse page.
It would be great if there were a PUT endpoint for username. The use case is sites like mine which transitioned to SSO, to get all the usernames synced. Then my plan A would have just worked.
My fallback plan I think is going to be to add another column to store discourse_username also in my DB along with discourse_id. This way, I can directly to their profile with username. The downside is that this username can change. So I need to daily scan all users to re-sync.
You can make a POST request to /admin/users/sync_sso for this. If you are using the Discourse API gem, you can use the gem’s sync_sso method for this. If you are not using the gem, see Sync DiscourseConnect user data with the sync_sso route for details about setting up the request.
