However we need to verify in a different service, using the Discourse API, if an email exists on the Discourse site. We can search for username or name via /u/search/users.json, but these do not appear to return the email address.
So can you search or query all emails for comparison?
Yes the link included in my initial question is “Discourse Meta/emails.json” but is there a way to get all user emails? … I would rather use the API then implement a plugin that allows SQL queries if at all possible.
Just to be clear, we are using the API, via secret key, I understand that the front-end would not have the same rights, can the API not have access though?
To give more details, we are have an app and discourse, both on Auth0 SSO authorization, however if someone logs into our app we want to make sure they have an account Discourse (and direct them to that link). Maybe it’s not the best way to check if Discourse has registered that email if they come to our site first. That is a link to Discourse in the event that the email has not been registered
If you are using trueDiscourse SSO, you can query the existence of a user by their external unique ID passed in the SSO payload using GET https://example.com/u/by-external/<EXTERNAL_ID>
