Hello!

I want to add a user tag to an application. The user tag would be a request attribute which is a java parameter. Here is my problem.

I capture a string which is look like this:

loginId=shortname, [mail=name.short@mailserver.com](mailto:mail=name.short@mailserver.com), givenName=Short, name=userID, sn=Name, department=DepartmentName

I want the user tag looks like this: “Name Short (loginID)”

I guess I should use a regex expression but I don’t know what.

Is it possible to do this way or is there any other way?

Currently, it is not possible to concatenate multiple server-side request attribute to form a User Tag.

I’d recommend using the Dtrum JavaScript API, because it provides with more flexibility for those custom user tag use cases.

[https://www.dynatrace.com/support/doc/javascriptapi/interfaces/dtrum\_types.DtrumApi.html#identifyUser](https://www.dynatrace.com/support/doc/javascriptapi/interfaces/dtrum_types.DtrumApi.html#identifyUser)

You’d need to call the&nbsp;identifyUser() method in your frontend to send your custom user tag into the platform.

Hope it helps!
