Hi @MashaoR
I found https://community.shopify.com/topic/1032547 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
