The master bill tracking request endpoint allows you to import a master bill to be tracked by OpenTrack.
Once a master bill has been imported for tracking, we will gather all of the containers associated with it, and you will be able to retrieve all available container status and milestone data via webhooks (if subscribed) or via the GET /containers endpoint.
In order to successfully provide tracking, please provide the Master Bill of Lading number issued by the carrier and SCAC code.
