OpenTrack provides key export visibility data for North American shipments. This information is collected from a growing number of sources and includes the following data points.

For a complete list of all available ocean and rail visibility data points, see Container Milestones.

Data	Description	API Property
EARLY RETURN DATE	The earliest date at which a container will be physically accepted for loading on a particular vessel at the origin port. Begins the Port Receiving Window	`earlyReturnDate`
CUTOFF DATE	The physical cutoff date for accepting new containers for loading on a particular vessel at the origin port. Ends the Port Receiving Window	`cutoffDate`
RAIL EARLY RETURN DATE	The earliest date at which a container will be physically accepted for loading on a particular vessel at the origin rail ramp. Begins the Rail Receiving Window	`railEarlyReturnDate`
RAIL CUTOFF DATE	The physical cutoff date for accepting new containers for loading at the origin rail ramp. Ends the Rail Receiving Window	`railCutoff`
DOCUMENT CUTOFF DATE	The cutoff date for accepting shipping instruction documentation.	`shippingInstructionCutoff`
VESSEL ETD	The ETD from the initial port of loading	`etdFromOrigin`
LOADING VESSEL	The vessel on which the container is first loaded at its port of loading. Can be different from the mother vessel if the container has a transshipment stop. Learn more here	`loadingVessel`
TERMINAL AT ORIGIN PORT	The terminal at the initial port of loading for the ocean leg	`terminalAtOriginPort`
ORIGIN RAIL MILESTONES	To see all Origin Rail milestones reported, click here	Inside the `history`
ORIGIN BARGE MILESTONES	To see all Origin Barge milestones reported, click here	Inside the `history`

Export Booking Visibility via API

Get itinerary, receiving windows, ETDs and ETAs even before containers have been pulled or assigned. This helps you better plan and execute origin operations.

Receiving Window Change Alerts

You can opt in to receive alerts when the receiving window changes for scheduled vessels. These alerts are available via email or webhook.

The alert will trigger when there is a change in either the Early Return Date or the Cutoff Date (both referring to the vessel at the ocean terminal).

🚫 Currently, alerts for Rail Cutoff Date or Document Cutoff Date changes are not supported. Let us know if this is something you’d like.

Subscribe via email

In the OpenTrack web app, go to your Notifications page under Settings and enable the Receiving Window Changes email alert under the Incidents section.

Subscribe via webhook

Ensure your webhook is subscribed to thecontainer.itinerary.changed and shipment.itinerary.updated events.

When a receiving window change occurs, the payload will include the changed receiving window properties in thechanges object:

earlyReturnDate and cutoffDate - receiving window at the ocean port terminal
railEarlyReturnDate and railCutoffDate - receiving window at the inland rail terminal
