When connected with ShipStation, orders will import into Order Desk from the original order source, then Order Desk will send order information to ShipStation. After you create shipments in ShipStation, Order Desk will retrieve the information and update the original order source.
To use Order Desk with ShipStation, you'll need to generate a set of API keys and enter them when setting up the ShipStation integration within Order Desk. For more details on setting up ShipStation in Order Desk, check out their article ShipStation: Integration Setup.

Order Desk originally created an integration to ShipStation in 2017 that was specifically for orders originating on Foxy (formerly FoxyCart). Order Desk has since created a more advanced integration that allows more communication between Order Desk and ShipStation.
The original integration is still active and is referred to by Order Desk as Legacy ShipStation. If using the Legacy integration, we recommend you follow this guide provided by Order Desk to learn how to switch to their updated ShipStation integration.
