call: keepAlive

Namespace: microsoft.graph

Make a request to this API every 15 to 45 minutes to ensure that an ongoing call remains active. A call that does not receive this request within 45 minutes is considered inactive and will subsequently end.

At least one successful request must be made within 45 minutes of the previous request, or the start of the call.

We recommend that you send a request in shorter time intervals (every 15 minutes). Make sure that these requests are successful to prevent the call from timing out and ending.

Attempting to send a request to a call that has already ended will result in a 404 Not-Found error. The resources related to the call should be cleaned up on the application side.

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.

Permission type	Least privileged permissions	Higher privileged permissions
Delegated (work or school account)	Not supported.	Not supported.
