application: addKey

Namespace: microsoft.graph

Add a key credential to an application. This method, along with removeKey can be used by an application to automate rolling its expiring keys.

Note

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

You should only provide the public key value when adding a certificate credential to your application. Adding a private key certificate to your application risks compromising the application.

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.

Applications that don’t have any existing valid certificates (no certificates have been added yet, or all certificates have expired), won’t be able to use this service action. You can use the Update application operation to perform an update instead.

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

Note

An application does not need any specific permission to roll its own keys.

HTTP request

You can address the application 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 /applications/{id}/addKey
POST /applications(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 application 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 application. 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 application 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. For more information about the claim types, see Claims payload.

Response

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