Create customAuthenticationExtension

Namespace: microsoft.graph

Create a new customAuthenticationExtension object. The following derived types are currently supported.

• onTokenIssuanceStartCustomExtension resource type.

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)	CustomAuthenticationExtension.ReadWrite.All	Not available.
Delegated (personal Microsoft account)	Not supported.	Not supported.
Application	CustomAuthenticationExtension.ReadWrite.All	Not available.

Important

In delegated scenarios with work or school accounts, the admin must be assigned a supported Microsoft Entra role or a custom role with a supported role permission. The following least privileged roles are supported for this operation:

• Authentication Extensibility Administrator
• Application Administrator

HTTP request

POST /identity/customAuthenticationExtensions

Request headers

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

Request body

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

You can specify the following properties when creating a customAuthenticationExtension. You must specify the @odata.type property with a value of the customAuthenticationExtension object type that you want to create. For example, to create an onTokenIssuanceStartCustomExtension object, set @odata.type to #microsoft.graph.onTokenIssuanceStartCustomExtension.

Property	Type	Description
authenticationConfiguration	customExtensionAuthenticationConfiguration	The authentication configuration for this custom extension. Required.
claimsForTokenConfiguration	onTokenIssuanceStartReturnClaim collection	Collection of claims to be returned by the API called by this custom authentication extension. Can be set for onTokenIssuanceStartCustomExtension object only. Used to populate claims mapping experience in Microsoft Entra admin center. Optional.
clientConfiguration	customExtensionClientConfiguration	The connection settings for the custom extension. Optional.
description	String	Description for the custom extension. Optional.
displayName	String	Display name for the custom extension. Required.
endpointConfiguration	customExtensionEndpointConfiguration	Configuration for the API endpoint that the custom extension will call. Required.

Response

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