Deprecation of the fulfillmentService.fulfillmentOrdersOptIn field


Action required

The fulfillmentOrdersOptIn field on the FulfillmentService GraphQL and REST API objects, along with the related mutations and endpoints, is being deprecated as the migration to the Fulfillment Orders API has been completed. All properly functioning fulfillment services now have the fulfillmentOrdersOptIn field set to true.

In the 2024-04 API version, the fulfillmentOrdersOptIn field becomes nullable and defaults to true in the fulfillmentServiceCreate mutation and the Create Fulfillment Service REST endpoint. This field will be removed from the mutation input and the REST endpoint parameters in the subsequent API version (2024-07). To prepare for the 2024-07 API version release, stop supplying the fulfillmentOrdersOptIn parameter when creating a new fulfillment service.
