Hi - @sandeepguntaka open to this but as you can see it needs more work to get the tests to work. Hopefully you're able to run the tests locally and debug them? If you get the tests passing again we can probably merge this.

I still see an issue with mocking guzzle's client, will fix that too and push the changes soon.
