Why isn't the Postman Shopify API showing a response?

[sonat_mis]

I try adding a carrier service the status is ok but there's no response, the response should be this.

HTTP/1.1 201 Created
{
"carrier_service": {
"id": 1036894960,
"name": "Shipping Rate Provider",
"active": true,
"service_discovery": true,
"carrier_service_type": "api",
"admin_graphql_api_id": "gid://shopify/DeliveryCarrierService/1036894960",
"format": "json",
"callback_url": "http://shipping.example.com/"
}
}

I also try the products Api create method but the Api work like a get method, did I missed something please help thanks 🙂
