Identify user from access token in custom rest API

Question

In my custom rest resource, I want to identify the user who made the API call. Since API call includes Authorization header with access token, can I get the user from this value?

Answer 1

Just use the UserInfo class, which:

Contains methods for obtaining information about the context user.

Specifically, you can get their Id, Name, Username, etc.

Id runningUserId = UserInfo.getUserId();
String runningUserName = UserInfo.getName();
String runningUserUsername = UserInfo.getUsername();

Answer 2

It works just like controllers.

UserInfo.getuserId() does the job
