How to call a post request (auth) on postman?

Question

I received a Java code. But I didn't know how the APIs in that code were loaded, so I wanted to try calling the postman. But I didn't know what to do with the authorization.

Here is my logcat from android studio:

D/OkHttp: --> POST https://test.com/api/test?lng=en
D/OkHttp: Content-Type: application/x-www-form-urlencoded
D/OkHttp: Content-Length: 13
D/OkHttp: Authorization: ██
D/OkHttp: id=12345
D/OkHttp: --> END POST (13-byte body)
