Shipwell's LTL and VLTL rate-share API: request rates from every eligible carrier on an account, book the one you choose, follow the freight the carrier is moving (by polling, or pushed to your own URL), and pull back the documents it produces along the way.

Capability	Operation	What it does
Rating	POST /rating/jobs	Request rates from every eligible carrier for a shipment.
	GET /rating/jobs/{id}	Read a rating job, and the rates it collected once it's terminal.
	GET /rating/jobs/{id}/rates/{rate_id}	Read one rate on its own — the URL a rate's self_link points at.
Dispatching	POST /dispatching/jobs	Book freight with a carrier, from a rate or from a stated shipment.
	GET /dispatching/jobs/{id}	Read a dispatch job and the carrier's answer.
	POST /dispatching/jobs/{id}/cancel	Cancel a booked dispatch.
Tracking	GET /tracking/timelines/{resource_id}	Read where a booked shipment has got to, and every movement its carrier reported.
Tracking webhooks	POST /tracking/webhooks	Register a URL; tracking changes for your freight are POSTed to it, signed.
	POST /tracking/webhooks/{id}/test	Send a signed test delivery and see what your endpoint answered.
Documents webhooks	POST /tracking/webhooks	Include documents.updated in event_names; document changes for your freight are POSTed to the same URL, signed.
Documents	GET /documents/{resource_id}	Read every document a carrier has produced for a resource so far.
	GET /documents/{resource_id}/{document_type}	The same collection, narrowed to one document type.
