CarrierService Not Posting To Our Callback URL

[DK_Mishra]

Hi @MashaoR 

I found https://community.shopify.com/c/shopify-apis-and-sdks/carrier-services-callback-url-not-being-called... and facing same issue.

CarrierService Not Posting To Our Callback URL.

My carrier_service file looks below:

carrier_service.json

{
"carrier_service": {
"name": "Freight Look Up",
"callback_url": "http://freightapi.ozvan.com.au/rates.php",
"service_discovery": true
}

Please just where I'm wrong
