Fedex API – SATURDAY_DELIVERY

Im having some trouble getting my SATURDAY_DELIVERY tag to work.

I can get the Saturday delivery from the rates and quotes api, so I know the addresses I’m using allow Saturday delivery.

Any help will be greatly appreciated.

I keep getting the following error:

[{"code":"ORGORDEST.SPECIALSERVICES.NOTALLOWED","message":"This special service type is not allowed for the origin/destination pair. Please update and try again","parameterList":[{"key":"SPECIAL_SERVICE_TYPE","value":"SATURDAY_DELIVERY"}]}

I’m wondering if someone else has come across this – Am I doing something wrong here? Iv tried mutiple different payloads with different addresses, iv tried sandbox API, Prod API, tried real addresses, different pickupType, different packagingTypes etc..

Here’s my sample payload

$payload = [
    "accountNumber" => [
        "value" => "*******"
    ],
    "labelResponseOptions" => "URL_ONLY",
    "requestedShipment" => [
        "shipDateStamp" => "2025-06-13", // Friday

        "serviceType" => "PRIORITY_OVERNIGHT",
        "packagingType" => "FEDEX_BOX", // Required for SATURDAY_DELIVERY in many areas
