Rate Multiple Shipments

Info

Rate a Single Shipment

If you need to just rate a single shipment, see the Get Shipping Rates Quickstart.

With ShipEngine you're able to process multiple shipments rates at the same time. Unlike in the Get Shipping Rates section, this process is asynchronous. If you subscribe to Web Hooks you will receive a notification when the batch is complete.

Additionally, as your shipments are rated, you can Retrieve Shipment Rates for your shipment manually.
