Extension Workflow

Managing Extensions via Object Storage

Extensions are stored as objects in the Object Storage system. You can:

• List extensions via GET /api/v1/resources/metas?object_type_id=6811b909-2e4b-45db-ab62-f14f515523cf
• Delete extensions via GET /api/v1/resources/:id/delete
• Check usage via GET /api/v1/resources/object_profile_usages?object_id=EXTENSION_ID

The extension object type ID is 6811b909-2e4b-45db-ab62-f14f515523cf.
