Function

Request sample

curl --request GET \ --url https://marketplace.walmartapis.com/v3/shipping/labels/carriers \ --header 'accept: application/json'

Modify your code

• Ensure the HTTP client sends a GET request to the supported carrier endpoint with an accept: application/json header.
• Keep the base URL pointed to Walmart Marketplace APIs.
• Call the https://marketplace.walmartapis.com/v3/shipping/labels/carriers path.
• Parse the JSON response to read the carrier list.
• Use carrierId when your workflow needs a carrier reference.

Response sample

{ "carriers": [ { "carrierId": "1000", "shortName": "FedEx", "carrierName": "FedEx" } ]
}

Result

The response shows one supported carrier in the carriers array:
