Hi,
Our clients have requested that we develop a plugin for Prestashop which communicates with our POS system through our own API.
Ideally, sales or other stock changes effected on the webshop should be reflected in real-time in the POS system and vice versa. So far I have only found information pertaining to accessing the Prestashop API to update stock data in from outside but not the opposite (communicate from the webshop to the POS API).
Is what I'm looking to do feasible and if so is there any documentation I could use as a jump-off point?
