Currently, Webflow does not send the following information to Shippo:
country of origin
Shippo requires this information in order to generate shipping labels for international orders. The absence of it forces merchants to manually add it for each individual order, which generates hours of extra work every single day. This effectively makes it untenable for merchants to accept international orders through Webflow.
I hesitate to even add this item to the Webflow Wishlist as it is not so much a feature request as a bug report, and a quite serious one at that.
