Problem
When Linnworks updates the Amazon order to mark it as shipped, it always sets the Carrier on Amazon to standard instead of the Carrier that is defined in the Vendor field of the Linnworks Postal Service Method.

Cause
Amazon has a list of fixed Carrier codes that are used to update the Carrier for the order through the API. If the Vendor name used does not match one of the predefined codes then Linnworks will set the carrier to Standard.

Solution
Change the Vendor in the appropriate Linnworks Postal Service Method to match the value required by Amazon.
See below for the list of available carriers and the Linnworks Vendor name to be used
