Additional Tracking Fields

There are additional fields like tracking_account_number and tracking_key that certain carriers need to authenticate your API request. Find the full list here.


Some carriers need to provide some additional information of the tracking (to ensure that you are really the owner of the tracking information) in addition to the tracking number. tracking_account_number and tracking_key represent the log in information and API key that the specific carrier may need to authenticate. These two fields are handled differently by specific carriers.

The existing fields, including tracking_origin_country_region, tracking_destination_country_region, tracking_postal_code, and tracking_state, have been marked as legacy fields and have been replaced by the new fields. However, the legacy fields are still available. Check the details below.
