List schemaExtensions

Namespace: microsoft.graph


APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

Get a list of schemaExtension objects created by any apps you own in the current tenant (that can be InDevelopment, Available, or Deprecated), and all other schema extensions owned by other apps that are marked as Available.

Note: The list will also contain schema extension definitions (marked as Available) created by other developers from other tenants. 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.


One of the following permissions is required to call this API. To learn more, including how to choose permissions, see Permissions.

Permission type Permissions (from least to most privileged)
Delegated (work or school account) User.Read, Application.Read.All
Delegated (personal Microsoft account) Not supported.
