Hi @nidhi.godha1, this API returns UUIDs (unique identifiers) for each occurrence of a Past Meeting.
Past Meetings are meetings which are no longer valid meeting IDs, meaning they are non-recurring meetings which were scheduled more than 30 days ago, or they are recurring meetings which were scheduled more than 1 year ago.
I would recommend using our Meeting Created and Meeting Ended events to subscribe to receive data each time a meeting has been scheduled or occurred. These events will provide UUIDs for each meeting occurrence.
If you have Dashboards enabled on your account, you can use the Dashboard APIs to List Meetings for the account and filter by past.
