Looking for some apiClient Examples #1

I'm looking to see if this extension will work in lieu of POSTMAN. I've got some basic JWT POSTS/GETS etc. That I'd like to accomplish. Do you have any example scripts. Maybe some that work with the restapi-server extension?
My task is to create a reset API script that will.

1. Complete a POST operation to get a JWT token from a login sequence.
2. Using the retrieved JWT token, perform a GET operation.

Thoughts?
