I’m working on a punch-out integration between a buyer’s procurement system and a supplier’s web app. The flow is as follows:
1.The buyer sends a setup request to the supplier.
2.The supplier responds with a URL, and the buyer is redirected from their procurement system to the supplier’s web app (web catalog).
3.The buyer shops on the supplier’s web app.
4.When the cart is ready, the buyer returns the cart to their procurement system.
