Where is the right place to pass parameters in a request?

Question

Computer networks

Hello! I need to make a GET request from an android application, like example.com/api/v3/scheme/123.json.
But along with the request, I need to send metadata: the application package and the application version.
And the question is, where do you put them? At first I thought in GET parameters, but somehow it's not comme il faut, probably better in headers?
How are you doing? What is the specification for this?
Thanks in advance!

Answer 1

probably better in the header's?

What's better?
