Retrieves a list of available shipping rates for the specified checkout

[poojafmile]

Hello, 
Am trying to retrieve available shipping rates for a specified checkout using the link : https://shopify.dev/api/admin/rest/reference/sales-channels/checkout#shipping_rates-2021-07
Am doing some test using postman :

GET     https://{shop}/admin/api/unstable/checkouts/{token}/shipping_rates.json

I have added to the headers:

Content-Type: application/json

X-Shopify-Access-Token: {password}


But am getting the error: 

"errors": "[API] This action requires merchant approval for read_checkouts scope."

My app is a private app and I have enabled every permission to Read and Write in the "Admin API permissions"

Can someone please help me here ?

Hey @poojafmile, the resource you shared is documenting APIs from the Sales Channel SDK and limited to public apps at this time - more info on build a sales channel here. That said based the results you are looking to achieve and because you are working with a private app, I would suggest talking a look into the CarrierService API that allows for a similar functionality. - Cheers!
