How to get carrier_identifier in orders API

Retired Boards Appdev Customers Discounts And Orders

Topic summary

A developer created a custom carrier service using Shopify’s Carrier Service API and successfully integrated it into the checkout process.

Core Issue:

  • When retrieving order data via the Orders API, the carrier_identifier field is missing from the response
  • The developer can see their carrier service reflected in the shipping_lines data, but cannot access the specific carrier identifier needed

Current Status:

  • The issue remains unresolved
  • A second user has confirmed experiencing the same problem, indicating this may be a broader technical limitation or documentation gap
  • No solution or workaround has been provided yet

The discussion includes reference images showing the API response structure, suggesting the missing field is critical for identifying which custom carrier was selected during checkout.
