List schemaExtensions

Namespace: microsoft.graph

Get a list of schemaExtension objects in your tenant. The schema extensions can be InDevelopment, Available, or Deprecated and includes schema extensions:

  • Created by any apps you own in the current tenant.
  • Owned by other apps that are marked as Available.
  • Created by other developers from other tenants and marked as Available. This is different from other APIs that only return tenant-specific data. Extension data created based on schema extension definitions is tenant-specific and can only be accessed by apps explicitly granted permission.

This API is available in the following national cloud deployments.
