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

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 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`

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 event.

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

newCutoffDate and previousCutoffDate
newEarlyReturnDate and previousEarlyReturnDate
