APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.
Enable a bot to reject an incoming call. The incoming call request can be an invite from a participant in a group call or a peer-to-peer call. If an invite to a group call is received, the notification contains the chatInfo and meetingInfo parameters.
The bot is expected to answer or reject the call before the call times out. The current timeout value is 15 seconds.
This API doesn't end existing calls that have already been answered. Use delete call to end a call.
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.

HTTP request
POST /app/calls/{id}/reject
POST /communications/calls/{id}/reject
Note: The /app path is deprecated. Going forward, use the /communications path.
In the request body, provide a JSON object with the following parameters.
Parameter
Type
Description
reason
String
The rejection reason. Possible values are None, Busy, and Forbidden.
callbackUri
String
Allows bots to provide a specific callback URI for the current call to receive later notifications. If this property isn't set, the bot's global callback URI is used instead. The URI must be https.
Response
If successful, this method returns a 202 Accepted response code. It doesn't return anything in the response body.
Examples
The following examples show how to call this API.
Example 1: Reject an incoming call with 'Busy' reason
