Missing trackingDetails in getShipment API Response for Amazon-Generated Tracking Numbers

[AmandeepSingh179]

We've identified an inconsistency in the getShipment operation of the Fulfillment Inbound API (v2024-03-20) regarding the tracking information returned in the response. The API is currently not returning the trackingDetails field for shipments that use Amazon shipping partners, where tracking numbers are automatically generated by Amazon. However, the same API successfully returns tracking information for shipments where tracking numbers were manually entered by us.

When testing the API behavior, we observed a clear pattern: calling getShipment for inbound shipments with manually entered tracking numbers returns complete responses with populated trackingDetails, while identical calls for shipments using Amazon shipping partners return responses missing the trackingDetails field entirely.

This issue significantly impacts us, as it prevents us from programmatically accessing tracking information for these shipments. Notably, this tracking information was previously available in Fulfillment Inbound API v0's getTransportDetails operation. Given this change in behavior between versions, we'd like to understand if this tracking information has been moved to a different field or endpoint in v2024-03-20?

We don't currently get tracking information (back from Amazon) other than getting the status -- however I can see that as necessary. I am curious to know if this is a bug or intentional as well as we were looking to track boxes in a more detailed fashion in the future.

Please keep me posted what you hear back - have you opened an API case?
