Hello,

When creating new meetings via the API, we have noticed that meeting IDs (the numerical ones) are being repeated. We managed to create a meeting with the same ID as a meeting that we created 6 months ago.  
In the API documentation we found that meeting IDs can expire after 30 days (example from [pastMeetings](https://marketplace.zoom.us/docs/api-reference/zoom-api/methods/#operation/pastMeetings) endpoint).

I wanted to ask to confirm if these IDs are, in fact, reutilized after 30 days and how that 30 days is calculated? Is it 30 days since meeting creation or since the last occurrence of that particular meeting?

I look forward to hearing back from you.  
Best regards,  
David Nascimento

Hi @david.nascimento ,

Depending on the type of meeting, the meeting ID can repeat, you can read more about it [here](https://support.zoom.us/hc/en-us/articles/201362373-Meeting-and-Webinar-IDs).
