🎉 ShipEngine is becoming ShipStation API 🎉

Over the next few months you'll notice the ShipEngine website, documentation portal, and dashboard being rebranded as ShipStation API. For our ShipEngine customers, you don't need to take any action or change any of your integrations in any way. All endpoints will remain the same and continue to function as they always have.

To learn more about what's coming, review our New ShipStation API page.

Ship Dates

Use the ship_date property in your shipment objects to specify the date the shipment will be shipped. By default, if no ship date is specified, ShipStation API assumes the ship date is the same day you created the shipment or label. ShipStation API will take the day of week into consideration. For example, if the carrier does not operate on Sundays, then the package ship date will be set to Monday instead.

Specifying the ship date for a label can help you to schedule a pickup, receive more accurate rates, and importantly, enable you to create manifests.

Requirements

The ship_date property uses the ISO 8601 standard format.
