Create schemaExtension

Namespace: microsoft.graph

Create a new schemaExtension definition and its associated schema extension property to extend a supporting resource type.

Schema extensions let you add strongly-typed custom data to a resource. The app that creates a schema extension is the owner app. Depending on the state of the extension, the owner app, and only the owner app, may update or delete the extension.

See examples of how to define a schema extension that describes a training course, use the schema extension definition to create a new group with training course data, and add training course data to an existing group.

This API is available in the following national cloud deployments.

Global service	US Government L4	US Government L5 (DOD)	China operated by 21Vianet

Permissions

Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

Permission type	Least privileged permissions	Higher privileged permissions
Delegated (work or school account)	Application.ReadWrite.All	Not available.
Delegated (personal Microsoft account)	Not supported.	Not supported.
Application	Application.ReadWrite.All and Directory.ReadWrite.All	Not available.

Note

Additionally for the delegated flow, the signed-in user must be the owner of the calling application OR the owner of the (application with the) appId used to set the owner property.

HTTP request

POST /schemaExtensions

Request headers

Name	Description
Authorization	Bearer {token}. Required. Learn more about authentication and authorization.
Content-Type	application/json

Request body

In the request body, supply a JSON representation of schemaExtension object.

The following table shows the properties that are required when you create a schema extension.

Parameter	Type	Description
description	String	Description for the schema extension.
id	String	The unique identifier for the schema extension definition. You can assign a value in one of two ways: Concatenate the name of one of your verified domains with a name for the schema extension to form a unique string in this format, {domainName}_{schemaName}. As an example, contoso_mySchema. NOTE: Only verified domains under the following top-level domains are supported: .com,.net, .gov, .edu or .org. Provide a schema name, and let Microsoft Graph use that schema name to complete the id assignment in this format: ext{8-random-alphanumeric-chars}_{schema-name}. An example would be extkvbmkofy_mySchema. This property cannot be changed after creation.
owner	String	(Optional) The appId of the application that is the owner of the schema extension. By default, the calling application's appId will be set as the owner. However, the property may be supplied on creation, to set the owner appId to something different from the calling app. In all cases, in the delegated flow, the signed-in user must be the owner of the application being set as the schema extension's owner. So, for example, if creating a new schema extension definition using Graph Explorer, you must supply the owner property, for an appId you own. Once set, this property is read-only and cannot be changed.
properties	extensionSchemaProperty collection	The collection of property names and types that make up the schema extension definition.
targetTypes	String collection	Set of Microsoft Graph resource types (that support schema extensions) that this schema extension definition can be applied to.

Response

If successful, this method returns 201 Created response code and schemaExtension object in the response body.

Example

Example 1: Creating a schema extension using a verified domain

Request

This example shows using a verified domain name, graphlearn, and a schema name, courses, to form a unique string for the id property of the schema extension definition. The unique string is based on this format, {domainName}_{schemaName}.

Example 3: Creating a schema extension setting the owner

Request

The following example shows how to create a schema extension setting the owner. In this scenario, the user of the application might not be the owner of the application (for example if you are using Microsoft Graph Explorer). In this case you should set the owner property to the appId of an application you own, otherwise you won't be authorized to create a schema extension. Set the owner property in the request, together with the JSON representation of the rest of the properties in the schemaExtension object.
