Update a Carrier Connection

Certain carriers allow you to update your account authentication details via ShipStation API without deleting the carrier and reconnecting it. This is useful if you've updated your carrier account password, API key, or other related credentials.

Requirements

The carrier_id and carrier_name for the account you wish to update (you can use the List Carriers endpoint to gather this informaiton)
The details for the properties you wish to update for that carrier (will vary by carrier)

Example Request & Response

Updating your carrier authentication details uses the following method and endpoint:

PUT /v1/connections/carriers/:carrier_name/:carrier_id

This example updates a Stamps.com account nickname, username, and password.
