How to find callChainID...?

Petri-X- As mentioned above, the callChainId is indeed available only when the recording is done for the call or meeting. This is obtained from the callRecord object, which is created after a call or meeting ends and is retained for 30 days.

To fetch the callRecord object, you can use the GET /communications/callRecords/{id} endpoint of the Microsoft Graph API. Here is an example of how to do this:

GET https://graph.microsoft.com/beta/communications/callRecords/{id}

However, the callChainId is not directly linked to the onlineMeeting object. The onlineMeeting object does not contain the callChainId property. Therefore, you cannot directly fetch the callChainId using the GET /me/onlineMeetings/{meetingId} endpoint.

To enrich the metadata of the recording with business data, you might need to maintain a mapping between the meetingId and the callChainId in your application. This mapping can be created when you receive the callRecord object after the meeting ends.

Please note that the APIs under the /beta version in Microsoft Graph are subject to change and their use in production applications is not supported.

For more information, you can refer to the following documentation:

• Get callRecord
• Get onlineMeeting
