Shopify experts are not able to reply this. This question is about Shopify app development. This app is regarding adding custom carrier services to show real time shipping rates.
I added (Shopify API Documentation Ref: CarrierService):
url: store_url."/admin/carrier_services.json"
Posted Data:
{
"carrier_service": {
"name": "My Carrier",
"callback_url": "http:\/\/blablabla.com",
"service_discovery": true
}
}
Now, the carrier is created and returns quotes as well. Everything is working fine.
There is just one issue: When we add any custom carrier to the shipping zone. Either it shows invalid services list i.e. services of Shopify default USPS, FedEx, or UPS services list OR shows:
There are no available services for the country you have selected Grammatically, there is no any way to add carriers to shipping zones. I am wondering: how Shopify decides what to show? This services list is also added in shipping zones, which is read only according to API.
Logically, it should either get services while creating a new carrier and show them, OR simply show any message which represents that custom carrier services will be available.
Invalid services from Shopify default carriers: Invalid services from Shopify default carriers
No services & wrong message: No services & wrong message
Set a static response on carrier service url (in this case "http://blablabla.com") it will set services automatically. Once they are visible in shipping zones then you can make them dynamic.
