Integrate Moodle 3.0+ with Opencart 2.1.0.2

Hi,
I have two questions regarding Moodle 3.0+ integration with opencart 2.1.0.2.

First question, Is it possible to integrate Moodle 3.0+ with Opencart 2.1.0.2? If so can someone please provide a demo site or live site that implements this kind of integration. Last question, Is there any documentation available?

Thanks.
