I built a site using concrete5 ecommerce addon, but now the client would (possibly) like to integrate it with a point-of-sale system (oooops).

Note: we built this site about a half year ago and when we scoped it out, there was no mention of getting a POS.

Anyhooooo...I was looking at this system called "Lightspeed" and they have an API, I was wondering if this was something that could interface with the ecommerce addon:

For example, could I just write a controller that hooks into their api and then updates the website with the correct number of products?
