New-MgSubscription

Module:

Microsoft.Graph.ChangeNotifications Module

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.

-LatestSupportedTlsVersion

Optional. Specifies the latest version of Transport Layer Security (TLS) that the notification endpoint, specified by notificationUrl, supports. The possible values are: v10, v11, v12, v13. 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.

With this new property in the subscription creation payload along with all existing properties, Webhooks 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.
