Hello, have you read about iControl API?

I think all that you need you can find on it.

For example, the bash code bellow extract the running config from the box as you can do in tmsh:

curl -vsku admin -X POST -H 'Content-Type: application/json' -d '{"command":"run", "utilCmdArgs":"-c \"tmsh show running-config\""}' https://localhost/mgmt/tm/util/bash

There are many ways to get virtual servers, pools, etc.

Please, refers to the manual.
