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.
In delegated scenarios, the admin must be assigned the Attribute Assignment Administrator role and the app granted the CustomSecAttributeAssignment.ReadWrite.All delegated permission.
In app-only scenarios using Microsoft Graph permissions, the app must be granted the CustomSecAttributeAssignment.ReadWrite.All application permission.
HTTP request
You can address the service principal using either its id or appId. id and appId are referred to as the Object ID and Application (Client) ID, respectively, in app registrations in the Microsoft Entra admin center.
In the request body, supply the values for relevant fields that should be updated. Existing properties that aren't included in the request body maintains their previous values or be recalculated based on changes to other property values. For best performance you shouldn't include existing values that haven't changed.
Property
Type
Description
accountEnabled
Boolean
true if the service principal account is enabled; otherwise, false.
Defines custom behavior that a consuming service can use to call an app in specific contexts. For example, applications that can render file streams may set the addIns property for its "FileHandler" functionality. This lets services like Microsoft 365 call the application in the context of a document the user is working on.
alternativeNames
String collection
Used to retrieve service principals by subscription, identify resource group and full resource IDs for managed identities.
appRoleAssignmentRequired
Boolean
Specifies whether an appRoleAssignment to a user or group is required before Microsoft Entra ID will issue a user or access token to the application. Not nullable.
The application roles exposed by the associated application. For more information, see the appRoles property definition on the application resource. Not nullable.
An open complex type that holds the value of a custom security attribute that is assigned to a directory object.
To update this property in delegated scenarios, the calling principal must be assigned the Attribute Assignment Administrator role and the app granted the CustomSecAttributeAssignment.ReadWrite.All delegated permission.
To update this property in app-only scenarios with Microsoft Graph permissions, the app must be granted the CustomSecAttributeAssignment.ReadWrite.All application permission.
The OAuth 2.0 permission scopes exposed by the associated application. For more information, see the oauth2PermissionScopes property definition on the application resource. Not nullable.
preferredSingleSignOnMode
string
Specifies the single sign-on mode configured for this application. Microsoft Entra ID uses the preferred single sign-on mode to launch the application from Microsoft 365 or the My Apps portal. The supported values are password, saml, external, and oidc.
replyUrls
String collection
The URLs that user tokens are sent to for sign in with the associated application, or the redirect URIs that OAuth 2.0 authorization codes and access tokens are sent to for the associated application. Not nullable.
servicePrincipalNames
String collection
Contains the list of identifiersUris, copied over from the associated application. Additional values can be added to hybrid applications. These values can be used to identify the permissions exposed by this app within Microsoft Entra ID. For example,
Client apps requesting permissions to this resource can use these URIs to specify needed permissions in the requiredResourceAccess property of their application manifest, or in the "API permissions" blade on the App registrations experience.
Client apps can specify a resource URI which is based on the values of this property to acquire an access token, which is the URI returned in the "aud" claim.
The any operator is required for filter expressions on multi-valued properties. Not nullable.
tags
String collection
Custom strings that can be used to categorize and identify the application. Not nullable.
tokenEncryptionKeyId
String
Specifies the keyId of a public key from the keyCredentials collection. When configured, Microsoft Entra ID issues tokens for this application encrypted using the key specified by this property. The application code that receives the encrypted token must use the matching private key to decrypt the token before it can be used for the signed-in user.
Response
If successful, this method returns a 204 No Content response code and updated servicePrincipal object in the response body.

Example 2: Assign a custom security attribute with a string value to a service principal
The following example shows how to assign a custom security attribute with a string value to a service principal.
Attribute set: Engineering
Attribute: ProjectDate
Attribute data type: String
Attribute value: "2022-10-01"
To assign custom security attributes, the calling principal must be assigned the Attribute Assignment Administrator role and must be granted the CustomSecAttributeAssignment.ReadWrite.All permission.
