Error 1021141

    "errorCode": "1021141",
    "message": "Invalid combination of Service Id and Parcel type.",
    "additionalInfo": "Invalid Rate Type."

USPS allows specific combinations of service (serviceId) and parcel type (parcelType). This error occurs when an incorrect combination is used.

Use the Get Carrier Rules API to retrieve the carrier’s shipment rules, including the available services and parcel types. Our recommendation is to apply the rules in your application. Another option is to use the Supported Services & Parcel Types to view the supported services and valid combinations.
