post https://api.fabric.inc/v3/shipments
To use this endpoint an “allocation” must exist for the order that is being shipped. When an order is placed, fabric sends allocation details to external merchant system to create order fulfillment requirement details in an external system. With reference to the allocation that is being shipped, users of this POST API can create shipment details for allocations.
Note: Shipment ID generated as part of the response is required for subsequent calls such as Acknowledge shipment (POST /shipments/{shipmentId}/acknowledge) and Get shipment (GET /shipments/{shipmentId}).
