Receiving/Sending cXML The majority of cXML documents are sent server-to-server via HTTP(S) POST requests where the POST body is the cXML.

Best Practice: HTTPS with TLS 1.2 should be used whenever possible Example cXML HTTP POST Request

Cart Transmission The PunchOutOrderMessage must be sent back to the eProcurement system from the shoppers web browser. Upon submitting the cart via an HTML form, the user will return to the eProcurement system and no longer be on the suppliers site.

Overview The cXML Edit/Inspect feature allows shoppers to return to a PunchOut site to make changes or view a cart that was previously checked out. This is accomplished by setting the value of the PunchOutSetupRequest[@operation] attribute to "edit" or "inspect" instead of the usual value of "create".
A common use case for this feature is to allow shoppers to adjust the quantities of items in their cart when the quantity changes may effect shipping costs or unit prices (tiered pricing).

The employee selects a supplier eCommerce site to "PunchOut" to (typically by clicking the supplier’s logo).
