I have a development store: carrierservicetesting.myshopify.com
I have enabled a carrierService, and I have double checked that it’s active. I created it using the GraphQL API, and if I request carrier services, I receive it, so I know it’s there. This is what I get from the API:
[ { active: true, callbackUrl: ‘https://script.google.com/macros/s/AKfycbz8MLwNANhEpdEMSLeMSZh_XfxXhdHzmmNHSSzh-CLTwx9tH7bAxdOv3ahysV_a-yNYvg/exec’, formattedName: ‘CustomCarrierService (Rates provided by app)’, id: ‘gid://shopify/DeliveryCarrierService/91631419672’, name: ‘CustomCarrierService’, supportsServiceDiscovery: true } ]
My setup is a Google Apps Script that receives the request and returns the response (happy to share more details if needed).
I have tried sending a request through Postman, and I receive the correct response: a 200OK with the following:
{
“rates”: [
{
“service_name”: “CustomCarrierService”,
“description”: “Test Description”,
“service_code”: “CUSTOM_SHIPPING”,
“currency”: “CLP”,
“total_price”: “3990”
}
]
}
Finally, I can also confirm that my script is in fact being triggered at checkout, and that the logged response is what Shopify expects. However, Shopify simply won’t show my rates.
I have dived through every content online I have seen and can’t find a solution. Support told me they can’t help me.
I have double checked that I have activated the “Automatically show new shipping services to customers when they become available” like I saw in some other post.
I am attaching what I see on my Shipping Setup screen as well in case it sheds more light.
Could someone please help me figure out what am I missing?
