WooCommerce Software License plugin customization

I need a little help with customizing the "WooCommerce Software License" plug-in from www.woosoftwarelicense.com You MUST be familiar with the API calls, adding necessary filters in PHP, and customizing the admin UI and the emails sent to customers. Please don't reply if you have not worked with this plug-in before. Documentation on how to make these changes is on their website, but I do not know PHP.

I need to retrieve the "Customer Name" in the "status-check" API call in addition to what is already retrieved..
I need to change "Domain", "Active Domain", etc. to "Device ID" or "Machine" since I license per machine, not per domain.
