List carriers
Returns a direct array of carriers, each with CarrierName and CarrierID. Use a returned CarrierID when creating or editing an asset.
By default, returns four carriers: UPS, USPS, FedEx, and DHL.
CarrierID narrows the array to that carrier. The response is still an array, and it is empty when nothing matches. Results are returned in a single response. Look up carriers when you configure your integration and reuse the result instead of requesting the list before every asset operation.
Authorizations
Send the access token returned by Login. Both access and refresh tokens are accepted; reserve refresh for credential renewal.
Query Parameters
Return only the carrier with this identifier. The response remains an array.
Account identifier. Defaults to your account.
