Namespace: microsoft.graph

Important

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.

Adds a key credential to a servicePrincipal. This method along with removeKey can be used by a servicePrincipal to automate rolling its expiring keys.

Note

Create servicePrincipal and Update servicePrincipal operations can continue to be used to add and update key credentials for any servicePrincipal with or without a user's context.

As part of the request validation for this method, a proof of possession of an existing key is verified before the action can be performed.

ServicePrincipals that don’t have any existing valid certificates (i.e.: no certificates have been added yet, or all certificates have expired), won’t be able to use this service action. Update servicePrincipal can be used to perform an update instead.

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 Directory.ReadWrite.All
Delegated (personal Microsoft account) Not supported. Not supported.
Application Application.ReadWrite.OwnedBy Application.ReadWrite.All, Directory.ReadWrite.All

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.

POST /servicePrincipals/{id}/addKey
POST /servicePrincipals(appId='{appId}')/addKey

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, provide the following required properties.

Property Type Description
keyCredential keyCredential The new servicePrincipal key credential to add. The type, usage and key are required properties for this usage. Supported key types are:
  • AsymmetricX509Cert: The usage must be Verify.
  • X509CertAndPassword: The usage must be Sign
passwordCredential passwordCredential Only secretText is required to be set which should contain the password for the key. This property is required only for keys of type X509CertAndPassword. Set it to null otherwise.
proof String A self-signed JWT token used as a proof of possession of the existing keys. This JWT token must be signed with a private key that corresponds to one of the existing valid certificates associated with the servicePrincipal. The token should contain the following claims:
  • aud: Audience needs to be 00000002-0000-0000-c000-000000000000.
  • iss: Issuer needs to be the ID of the servicePrincipal that initiates the request.
  • nbf: Not before time.
  • exp: Expiration time should be the value of nbf + 10 minutes.

For steps to generate this proof of possession token, see Generating proof of possession tokens for rolling keys.

Response

If successful, this method returns a 200 OK response code and a new keyCredential object in the response body.
