Create a shipment request for asynchronous processing. Unlike the standard Create Shipment endpoint, this endpoint performs only initial validation on the shipment data and does not return a label in the response.
If the request passes validation and a Shipments Webhook is configured, the shipment is queued for background processing. The response from the Create Shipment request will be pushed to the webhook.
The immediate API response contains only a RequestId, which can be used to track and correlate the request with subsequent webhook responses.
Note: This endpoint must only be used when the Shipments Webhook is configured within the SAPIENT UI.
