There doesn't seem to be any API available for this. However, you can use Microsoft Graph API to get change notifications by subscribing to required resources.
Please refer: https://learn.microsoft.com/en-us/graph/api/resources/webhooks?view=graph-rest-1.0
You can subscribe to Teams Meeting status information updates: /communications/onlineMeetings/{meeting-id} , which is available in only the beta endpoint.
