We are a reseller of Universal POS software. We have a couple of customers that want an online ordering webpage linked to their existing Universal POS. I have set up an online store with Shopify to learn how it functions. The customers are small restaurants and Universal tells me the API it was designed more for Retail. Do you know what are the limitations for restaurant? Also do we need any additional upgrades or apps other than the Universal API to make this integrate? Will the API work with the Basic Shopify?
