REST API to Webflow?

Hi there.
I need some help. I built an e-commerce site in Webflow. My customer works with a cash register system that has a REST API. The intention is that when an item is physically sold in the store, the stock - which I manage in Webflow - is adjusted. Then the site must be updated so that the current stock is visible.

Who can help me with this?

@Erwin, depending on the cash register system there may be a pre-built integration using something like Zapier, however, if not you’ll need to build something custom. You could look into using something like Flask and Heroku to accomplish this, but it will take a decent level of development experience to accomplish this.
