Order Management apps can no longer fulfill orders that are assigned to a different fulfillment service

As of 2024-10, the write_third_party_fulfillment_orders access scope permission will change for fulfillment creation. This access scope will no longer allow order management apps to fulfill fulfillment orders assigned to locations owned by other fulfillment service apps. Order management apps will still be able to access and manage these orders, only fulfillment creation will be prohibited.

The write_assigned_fulfillment_orders and write_merchant_managed_fulfillment_orders access scopes will remain unchanged. Fulfillment service apps will continue to be able to fulfill orders assigned to them as long as they have the write_assigned_fulfillment_orders access scope. Fulfillment orders assigned to merchant managed locations will continue to be fulfillable by order management apps as long as they have the write_merchant_managed_fulfillment_orders access scope.

Apps can confirm whether or not fulfillment creation is possible by querying the available supportedActions through either the GraphQL or REST APIs. If the fulfillment order is assigned to a merchant managed location or to the fulfillment service performing the query and it is in a fulfillable state, CREATE_FULFILLMENT will be returned as a possible option.
