OpenEMR v7.0 "oauth2/default/userinfo" endpoint returns 200 with no user information

OpenEMR Development

I’m currently working on integrating OpenEMR with my application using OAuth2. Everything seems to be functioning correctly, except for one critical issue. When I make a request to the /oauth2/default/userinfo endpoint, it returns a status code 200, but I don’t receive any user information in the response.

My goal is to identify the user who is currently logged in to my application so that I can save certain preferences specific to that user.

Here is a simplified version of my OAuth2 flow:

  1. The user logs in through OpenEMR’s OAuth2 authentication.
  2. After successful authentication, my application requests user information from /oauth2/default/userinfo.
  3. Instead of receiving user details, I get an empty response with a 200 status code.

I’ve double-checked my OAuth2 configuration, and it seems to be set up correctly. Is there something specific I need to do to ensure that the /oauth2/default/userinfo endpoint returns the user’s information?

Any guidance on how to resolve this issue or suggestions for troubleshooting would be greatly appreciated. Thank you!

I haven’t done much with the userinfo endpoint but I do know you can use the id_token to grab a bunch of the user info. Have you looked into using that?

@sjpadgett might be able to chime in on the /userinfo as he put together the OIDC endpoints for OpenEMR.

Thank you for your prompt response!

Could you share a guide or example for using the id_token to extract user info?

I don’t recall implementing the user info endpoint. I currently have no plans in doing so however if someone wants to push a PR I’d be more than happy to look over.
As far as I’m concerned this is the purpose for the ID token. A web search can provide how to decode that token.
