Introduction
ShipStation is a multi-carrier platform which provides an API interface allowing UltraCart to provide your customers with shipping rates from the carrier of your choice.
UltraCart has three different engines with connections to ShipStation: Channel Partners, Shipping, and Distribution Center fulfillment.
If you need information on configuring ShipStation to provide shipping ratings and print labels, you are reading the right document.
If you need information configuring UltraCart to send orders to ShipStation fulfillment and receive tracking numbers in return, please see Configuring ShipStation (Distribution Center Transport Mechanism).
If you need information on configuring ShipStation as a Channel Partner, please see ShipStation Channel Partner Integration .
All three areas (ratings, distribution centers, and channel partners) use separate credentials to allow for different ShipStation stores.
