The current integration between C&D does not send over the shipping service used when shipping orders back to Shopify. The only information that is sent back to Shopify is the Carrier (Royal Mail) and the tracking ID.

The Shipping service is needed for the likes of Amazon to meet their Valid Tracking Rate metric. Under the current API not sending this to Shopify the correct and valid Shipping information cannot be sent to Amazon through a Shopify integration. Instead business customers like ourselves have to rely on either direct shipping through C&D to Amazon or via a 3rd Party app on Shopify that will transmit this.

This is vital for businesses to have the flexibility to choose from the shipping manager they want to use without having to compromise.

Summary: C&D needs to send the Shipping Service use along with the carrier and tracking ID to Shopify via the current integration.
