Current Logged in User?

Hello,

I'm working on a third-party app to provide some extra functionality for our clients whilst being tightly integrated with IMIS.

Is there anyway of calling an API endpoint that will return the 'Current Logged in' users details, identified by the Bearer Token itself?

I know about the User endpoint and you can query it based on a query string of userName or userId, however I'm trying to use an Authentication Module which attempts to return the user details from a GET request simply by using the Bearer Token returned from the Token call.

I also can't use the 'Pass Through' method as the Authentication Module works server-side and so I cannot access the __ClientContext data.

Any advice would be appreciated.

Thankyou
