Shopify Custom shipping api not sending data to callback url

HI There
We created a custom shipping private app using this api request ........its created successfully and available in admin panel as well. (Check Attached screenshot)

And here is api response from shopify which proves that custom shipping service is created successfully
"id": 33121468490,
"name": "Vanna Carrier",
"active": true,
"service_discovery": true,
"carrier_service_type": "api",
"admin_graphql_api_id": "gid:\/\/shopify\/DeliveryCarrierService\/33121468490",
"format": "json",
"callback_url": "http:\/\/\/workscripts\/gso.php"

But problem is while checking out from frontend it never calls this callback url that we supplied while creating this carrier service we do have logging enabled on this url so anything that comes logs but it seems like request from shopify never comes to our callback url


Response from our callback url 

{"rates":[{"service_name":"Endertech Overnight","description":"Service insurance included","service_code":"ETON","total_price":"000","currency":"USD","min_delivery_date":"2020-08-28 11:34:01 +0000","max_delivery_date":"2020-08-29 11:34:01 +0000"},{"service_name":"Endertech Regular","description":"Service insurance includ","service_code":"ETREG","total_price":"000","currency":"USD","min_delivery_date":"2020-08-30 11:34:01 +0000","max_delivery_date":"2020-09-03 11:34:01 +0000"}]}

Hey @Marvin1,

If you haven't already, double check the address that's being used to test, and make sure the products in your cart are assigned to the shipping zone with your app rates. If you're still seeing an issue, please  provide a checkout id where you've seen the issue previously, or a shop id from a shop where this issue is present. I can use that to test further and hopefully spot the issue.
