Fulfillment service callback url is now optional
UpdateUnverifiedAdded Sep 24, 2026
As of the Admin API version 2026-01, the callbackUrl argument in the fulfillmentServiceCreate and fulfillmentServiceUpdate mutations is now optional. If your app's fulfillment services do not have a callback URL but have either inventoryManagement or trackingSupport enabled, they will need to submit the information required by these features via the API.
