Update: Support For API Version 2022-04 Extended To June 30, 2023
TL;DR: Any public, custom or private apps leveraging the deprecated Fulfillment API endpoints will stop working on June 30, 2023 in favor of the new Fulfillment Order API.
All apps that have not migrated by that date may stop working as intended. Please check our migration guide and take action as soon as possible to avoid any interruptions.
