Consignment API — push consignments in, get labels back

The Consignment API lets your own order or warehouse system push consignments directly into our label allocation engine and get label numbers back, synchronously, in the same call — for a developer integrating a system that already creates orders and wants labels back without anyone opening the portal.

Getting a key
