We have a recurring meeting that runs for a few days. I am getting different UUID for the same meeting if I call `/meetings` and `/past\_meetings`` API. For example:

```auto
https://api.zoom.us/v2/meetings/8579198292900
https://api.zoom.us/v2/past_meetings/8579198292900

```

The `/past_meetings` call seems to be returning the UUID of the last occurrence. This is very strange. Is this the expected behavior?

Hi @Bibhas  
Thanks for reaching out to the Zoom Developer Forum, I am happy to help here!  
Yes, it is an expected behavior. Each occurrence will generate a unique UUID, because each meeting has its own instance.

Also note that when you call GET/meetings/ you are getting the UUID generated for the next occurrence and with GET/past\_meetings, you are getting the UUID for the meeting instance/occurrence that already passed.

I am linking here a useful guide to understand meeting IDs and UUIDs.
