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](https://developers.opentrack.co/docs/container-voyage-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.

This helps you better plan and execute origin operations. [To learn more about Export Booking Visibility via API, click here.](https://developers.opentrack.co/docs/early-stage-bookings-via-api) # 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](https://dashboard.opentrack.co/settings/notifications) under **Settings** and enable the **Receiving Window Changes** email alert under the **Incidents** section. ### Subscribe via webhook Ensure your webhook is subscribed to the`container.itinerary.changed` and `shipment.itinerary.updated` events. When a receiving window change occurs, the payload will include the changed receiving window properties in the`changes` object: * `earlyReturnDate` and `cutoffDate` - receiving window at the ocean port terminal * `railEarlyReturnDate` and `railCutoffDate` - receiving window at the inland rail terminal # Receiving Window Coverage Map The following table outlines expected Receiving Window data based on ocean carrier and loading terminal combinations.
