I have created an REST API and it will be consumed from an outlook web mail addins which I also build. Now, I want to make sure that only those who logged-in in Outlook web mail can get access to my API.

So my question now, is how to get the active user in outlook web mail? Is that possible?

You can authenticate your user for service you have implemented. There are several ways of doing this, please read here: https://learn.microsoft.com/en-us/office/dev/add-ins/outlook/authentication.

Please read about Addin API 'getUserIdentityTokenAsync' which looks like what you are looking for in this case.
