Update servicePrincipal

Namespace: microsoft.graph

[!INCLUDE beta-disclaimer]

Update the properties of servicePrincipal object. This API can also update an agentIdentityBlueprintPrincipal object when the @odata.type property is set to #microsoft.graph.agentIdentityBlueprintPrincipal.

Important

Using PATCH to set passwordCredential is not supported. Use the addPassword and removePassword methods to update the password or secret for a servicePrincipal.
Service principals inherit specific properties from their associated app registrations. These properties are synchronized from the app registration, but the synchronization isn't immediate or continuous. Sometimes, updating a service principal may prompt the directory to refresh properties from the app registration, causing updates that weren't part of the original request.

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.

[!INCLUDE permissions-table]

[!INCLUDE rbac-serviceprincipal-apis-create-update-upsert]

Permissions for specific scenarios

To update the customSecurityAttributes property:
- 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.

PATCH /servicePrincipals/{id}
PATCH /servicePrincipals(appId='{appId}')

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 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.
addIns	addIn	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.
appRoles	appRole collection	The application roles exposed by the associated application. For more information, see the appRoles property definition on the application resource. Not nullable.
customSecurityAttributes	customSecurityAttributeValue	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.
displayName	String	The display name for the service principal.
homepage	String	Home page or landing page of the application.
isDisabled	Boolean	Specifies whether the service principal of the app in a tenant or across tenants for multi-tenant apps can obtain new access tokens or access protected resources. When set to `true`, existing tokens remain valid until they expire based on their configured lifetimes, and the app stays visible in the Enterprise apps list but users cannot sign in.`true` if the application is deactivated (disabled); otherwise `false`.
keyCredentials	keyCredential collection	The collection of key credentials associated with the service principal. Not nullable.
loginUrl	String	Specifies the URL where the service provider redirects the user to Microsoft Entra ID to authenticate. Microsoft Entra ID uses the URL to launch the application from Microsoft 365 or the Microsoft Entra My Apps. When blank, Microsoft Entra ID performs IdP-initiated sign-on for applications configured with SAML-based single sign-on. The user launches the application from Microsoft 365, the Microsoft Entra My Apps, or the Microsoft Entra SSO URL.
logoutUrl	String	Specifies the URL that will be used by Microsoft's authorization service to log out a user using front-channel, back-channel or SAML logout protocols.
notificationEmailAddresses	String collection	Specifies the list of email addresses where Microsoft Entra ID sends a notification when the active certificate is near the expiration date. This is only for the certificates used to sign the SAML token issued for Microsoft Entra Gallery applications.
publishedPermissionScopes	permissionScope collection	The OAuth 2.0 permissions 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 Microsoft Entra My Apps. The supported values are password, saml, external, and oidc.
preferredTokenSigningKeyEndDateTime	DateTimeOffset	Specifies the expiration date of the keyCredential used for token signing, marked by preferredTokenSigningKeyThumbprint.
preferredTokenSigningKeyThumbprint	String	Reserved for internal use only. Don't write or otherwise rely on this property. May be removed in future versions.
publisherName	String	The display name of the tenant in which the associated application is specified.
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.
samlSingleSignOnSettings	samlSingleSignOnSettings	The collection for settings related to saml single sign-on.
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 that 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	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.
