Background
Some products we are releasing will have the ability to be shipped via USPS First Class Mail.
Currently we have USPS Parcel Select Ground hard-coded into the ship method we are sending to the 3PL
(Possible) Solution
Add a “Shipping Code” property to each product.
This “Shipping Code” property will populate the <ShipMethod> on the 'Create Order 3PL API (3PL API sheet re-attached)
