I work for a custom apparel company and we have recently started handling eCommerce fulfillment for some clients. I have a brewery client that uses Toast point of sale and they'd like us to start fulfilling eCom orders from a Toast webstore. However Toast does not integrate with our shipping suite (ShipStation). I've heard that Toast integrates with Shopify, but I'm struggling to find clear guidance on how to set that up. Can someone get me started? Thanks!
