Create subscription

Namespace: microsoft.graph

Subscribes a listener application to receive change notifications when the requested type of changes occur to the specified resource in Microsoft Graph.

To identify the resources for which you can create subscriptions and the limitations on subscriptions, see Set up notifications for changes in resource data: Supported resources.

Some resources support rich notifications, that is, notifications that include resource data. For more information about these resources, see Set up change notifications that include resource data: Supported resources.

This API is available in the following national cloud deployments.

Permissions

Creating a subscription requires read permission to the resource. For example, to get change notifications on messages, your app needs the Mail.Read permissions.

Depending on the resource and the permission type (delegated or application) requested, the permission specified in the following table is the least privileged required to call this API. To learn more, including taking caution before choosing the permissions, search for the following permissions in Permissions.

chatMessage

chatMessage subscriptions can be specified to include resource data. If specified to include resource data (includeResourceData set to true), encryption is required. The subscription creation fails if an encryptionCertificate isn't specified for such subscriptions.

You must use the Prefer: include-unknown-enum-members request header to get the following values in chatMessage messageType evolvable enum: systemEventMessage for /teams/{id}/channels/{id}/messages and /chats/{id}/messages resource.

conversationMember

conversationMember subscriptions can be specified to include resource data. If specified to include resource data (includeResourceData set to true), encryption is required. The subscription creation fails if an encryptionCertificate isn't specified.

team, channel, and chat

team, channel, and chat subscriptions can be specified to include resource data. If specified to include resource data (includeResourceData set to true), encryption is required. The subscription creation fails if an encryptionCertificate isn't specified.

You can use the notifyOnUserSpecificProperties query string parameter when you subscribe to changes in a particular chat or at user level. When you set the query string parameter notifyOnUserSpecificProperties to true during subscription creation, two types of payloads are sent to the subscriber. One type contains user-specific properties, and the other is sent without them. For more information, see Get change notifications for chats using Microsoft Graph.

Request example

Specify the model query parameter in the resource property in the request body.

POST https://graph.microsoft.com/v1.0/subscriptions
Content-type: application/json

{
   "changeType": "created",
   "notificationUrl": "https://webhook.azurewebsites.net/api/send/myNotifyClient",
   "resource": "chats/getAllMessages?model=A",
   "expirationDateTime":"2016-11-20T18:23:45.9356913Z",
   "clientState": "secretClientValue",
   "latestSupportedTlsVersion": "v1_2"
}

driveItem

More limitations apply to subscriptions on OneDrive items. The limitations apply to creating as well as managing (getting, updating, and deleting) subscriptions.

On a personal OneDrive, you can subscribe to the root folder or any subfolder in that drive. On OneDrive for work or school, you can subscribe to only the root folder. Change notifications are sent for the requested changes on the subscribed folder or any file, folder, or other driveItem instances in its hierarchy. You can't subscribe to drive or driveItem instances that aren't folders, such as individual files.

OneDrive for work or school and SharePoint support sending your application notifications of security events that occur on a driveItem. To subscribe to these events, add the prefer:includesecuritywebhooks header to your request to create a subscription. After the subscription is created, you will receive notifications when the permissions on an item change. This header applies to SharePoint and OneDrive for work or school but not consumer OneDrive accounts.

contact, event, and message

You can subscribe to changes in Outlook contact, event, or message resources and optionally specify in the POST request payload whether to include encrypted resource data in notifications.

Creating and managing (getting, updating, and deleting) a subscription requires a read scope to the resource. For example, to get change notifications on messages, your app needs the Mail.Read permission. Outlook change notifications support delegated and application permission scopes. Note the following limitations:

• Delegated permission supports subscribing to items in folders in only the signed-in user's mailbox. For example, you can't use the delegated permission Calendars.Read to subscribe to events in another user’s mailbox.

• To subscribe to change notifications of Outlook contacts, events, or messages in shared or delegated folders:

  • Use the corresponding application permission to subscribe to changes of items in a folder or mailbox of any user in the tenant.
  • Don't use the Outlook sharing permissions (Contacts.Read.Shared, Calendars.Read.Shared, Mail.Read.Shared, and their read/write counterparts), as they do not support subscribing to change notifications on items in shared or delegated folders.

onlineMeetings, presence

Subscriptions on onlineMeetings and presence require the encryptionCertificate and encryptionCertificateId property when creating a subscription for notifications with encrypted resource data. For more information, see setting up change notifications to include resource data. For details about online meeting subscriptions, see Get change notifications for online meetings.

virtualEventWebinar

Subscriptions on virtual events support only basic notifications and are limited to a few entities of a virtual event. For more information about the supported subscription types, see Get change notifications for Microsoft Teams virtual event updates.

Example

Request

In the request body, supply a JSON representation of the subscription object. The clientState and latestSupportedTlsVersion fields are optional.

This request creates a subscription for change notifications about new mail received by the currently signed-in user.

Duplicate subscription behavior

Duplicate subscriptions aren't allowed. When a subscription request contains the same values for changeType and resource that an existing subscription contains, the request fails with an HTTP error code 409 Conflict, and the error message Subscription Id <> already exists for the requested combination.

Resources examples

The following are valid values for the resource property.

Response

The following example shows the response.

Note: The response object shown here might be shortened for readability.

Notification endpoint validation

The subscription notification endpoint (specified in the notificationUrl property) must be capable of responding to a validation request as described in Set up notifications for changes in user data. If validation fails, the request to create the subscription returns a 400 Bad Request error.
