Shopify Removes Automatic Carrier Service Addition to Default Shipping Profile

What Changed

Shopify has introduced a breaking change in GraphQL Admin API version 2026-10 that affects how carrier services integrate with shipping profiles. Starting with this API version, creating a carrier service no longer automatically adds it to the shop’s General shipping profile.

This change applies to carrier services created through both the GraphQL Admin API’s carrierServiceCreate mutation and the REST Admin API’s POST /admin/api/{version}/carrier_services.json endpoint. Previously, active API carrier services were automatically added to all eligible shipping zones within the General shipping profile upon creation.

Impact on Shopify App Developers

Developers building shipping rate calculation apps or custom carrier integrations need to update their implementation workflows. Apps that relied on automatic carrier service activation will now require additional API calls to manually add carrier services to the appropriate shipping profiles and zones.

This change affects the initial setup flow for shipping apps, as merchants will no longer see newly created carrier services immediately available in their shipping settings without explicit configuration.

Practical Implications

Developers should audit their carrier service creation logic before migrating to API version 2026-10. Apps will need to implement explicit profile and zone assignment using the appropriate shipping profile APIs to maintain the same merchant experience.

Existing carrier services created before this API version remain unaffected. The change only applies to new carrier services created using version 2026-10 and later. Developers should update their app documentation and onboarding flows to reflect the new manual configuration requirements for shipping profile integration.
