subscription resource type

Namespace: microsoft.graph

A subscription allows a client app to receive change notifications about changes to data in Microsoft Graph.

For more information about subscriptions and change notifications, including resources that support change notifications, see Set up notifications for changes in resource data.

Methods

Method Return Type Description
Create subscription subscription Subscribes a listener application to receive change notifications when Microsoft Graph data changes.
Update subscription subscription Renews a subscription by updating its expiration time.
List subscriptions subscription Lists active subscriptions.
Get subscription subscription Reads properties and relationships of subscription object.
Delete subscription None Deletes a subscription object.
reauthorize None Reauthorize a subscription when you receive a reauthorizationRequired challenge.

Properties

Property Type Description
applicationId String Optional. Identifier of the application used to create the subscription. Read-only.
changeType String Required. Indicates the type of change in the subscribed resource that will raise a change notification. The supported values are: created, updated, deleted. Multiple values can be combined using a comma-separated list.

Note:
  • Drive root item and list change notifications support only the updated changeType.
  • User and group change notifications support updated and deleted changeType. Use updated to receive notifications when user or group is created, updated or soft deleted. Use deleted to receive notifications when user or group is permanently deleted.
  • clientState String Optional. Specifies the value of the clientState property sent by the service in each change notification. The maximum length is 128 characters. The client can check that the change notification came from the service by comparing the value of the clientState property sent with the subscription with the value of the clientState property received with each change notification.
    creatorId String Optional. Identifier of the user or service principal that created the subscription. If the app used delegated permissions to create the subscription, this field contains the id of the signed-in user the app called on behalf of. If the app used application permissions, this field contains the id of the service principal corresponding to the app. Read-only.
    encryptionCertificate String Optional. A base64-encoded representation of a certificate with a public key used to encrypt resource data in change notifications. Optional but required when includeResourceData is true.
    encryptionCertificateId String Optional. A custom app-provided identifier to help identify the certificate needed to decrypt resource data.
    expirationDateTime DateTimeOffset Required. Specifies the date and time when the webhook subscription expires. The time is in UTC, and can be an amount of time from subscription creation that varies for the resource subscribed to. For the maximum supported subscription length of time, see the table below.
    id String Optional. Unique identifier for the subscription. Read-only.
    includeResourceData Boolean Optional. When set to true, change notifications include resource data (such as content of a chat message).
    latestSupportedTlsVersion String Optional. Specifies the latest version of Transport Layer Security (TLS) that the notification endpoint, specified by notificationUrl, supports. The possible values are: v1_0, v1_1, v1_2, v1_3.

    For subscribers whose notification endpoint supports a version lower than the currently recommended version (TLS 1.2), specifying this property by a set timeline allows them to temporarily use their deprecated version of TLS before completing their upgrade to TLS 1.2. For these subscribers, not setting this property per the timeline would result in subscription operations failing.

    For subscribers whose notification endpoint already supports TLS 1.2, setting this property is optional. In such cases, Microsoft Graph defaults the property to v1_2.
    lifecycleNotificationUrl String Required for Teams resources if the expirationDateTime value is more than 1 hour from now; optional otherwise. The URL of the endpoint that receives lifecycle notifications, including subscriptionRemoved, reauthorizationRequired, and missed notifications. This URL must make use of the HTTPS protocol. For more information, see Reduce missing subscriptions and change notifications.
    notificationQueryOptions String Optional. OData query options for specifying value for the targeting resource. Clients receive notifications when resource reaches the state matching the query options provided here. With this new property in the subscription creation payload along with all existing properties, Webhooks will deliver notifications whenever a resource reaches the desired state mentioned in the notificationQueryOptions property. For example, when the print job is completed or when a print job resource isFetchable property value becomes true etc.

    Supported only for Universal Print Service. For more information, see Subscribe to change notifications from cloud printing APIs using Microsoft Graph.
    notificationUrl String Required. The URL of the endpoint that will receive the change notifications. This URL must make use of the HTTPS protocol. Any query string parameter included in the notificationUrl property will be included in the HTTP POST request when Microsoft Graph sends the change notifications.
    notificationUrlAppId String Optional. The app ID that the subscription service can use to generate the validation token. This allows the client to validate the authenticity of the notification received.
    resource String Required. Specifies the resource that will be monitored for changes. Do not include the base URL (https://graph.microsoft.com/v1.0/). See the possible resource path values for each supported resource.

    Subscription lifetime

    Subscriptions have a limited lifetime. Apps need to renew their subscriptions before the expiration time; otherwise, they need to create a new subscription. Apps can also unsubscribe at any time to stop getting change notifications.

    The following table shows the maximum expiration times for subscriptions per resource in Microsoft Graph.
