When using [https://api.zoom.us/v2/report/users/{user}meetings](https://api.zoom.us/v2/report/users/%7Buser%7Dmeetings) a number of meetings are returned but the “id” property is identical for different meetings. The “uuid” is unique but since one has to user the “id” value to pass on to Get Meeting Recordings this is of no use. Note the meeting id is the same (2168742555) even though the meetings were on different days. { “duration”: 128, “end\_time”: “2020-09-01T15:42:51Z”, “host\_id”: “xxxxxxxxxxxxxxxxx”, “id”: 2168742555, “participants\_count”: 7, “start\_time”: “2020-09-01T13:37:48Z”, “topic”: “xxxxxxxxxxxxxxxxxxxxx”, “total\_minutes”: 495, “type”: 4, “user\_email”: “xxxxxxxxx”, “user\_name”: “xxxxxxxxxxxx”, “uuid”: “UwIIBBxAS5aKrtvtOjd8gg==” }, { “duration”: 46, “end\_time”: “2020-09-04T10:42:20Z”, “host\_id”: “xxxxxxxxxx”, “id”: 2168742555, “participants\_count”: 3, “start\_time”: “2020-09-04T09:58:57Z”, “topic”: “xxxxxxxxxxxxx”, “total\_minutes”: 125, “type”: 4, “user\_email”: “xxxxxxxxxxxx”, “user\_name”: “xxxxx”, “uuid”: “VSM+aCkXTxy/62nfqiNuwA==” }, ---

Hey @burden.richard Thanks for posting on the Zoom Devforum! I am still learning, but I will try my best to help answer your question. 🙂 Checkout these related threads that may have the answer you are looking for: > [@Is the Meeting ID unique across the users?](https://devforum.zoom.us/t/-/7393): > > Hi, Description Is the meeting ID in each recording by the user unique across the users? Thanks, smsivanesan > [@Unique meeting ID conditions](https://devforum.zoom.us/t/-/3207): > > Hi, I’m working on an application which requires to create multiple Zoom meeting links, for different people. Currently when I create the zoom links using the API, some of the IDs generated are the same, so a person could have two different events in two different days with the same ID and that could generate problems. Is there a condition for zoom to guaranty generation of always a different ID? Like a different topic, or start\_date, etc. I would like for this meetings to be recurring because … If these threads did not help, please let us know by replying back here and someone from the Developer Relations team will get back to you shortly.

I don’t think either of those posts answer my question. As the meeting id is required for other api calls - for example getting the recording list, how does one know which particular meeting the additional data refers to - eg a recording file? ---

Hi @burden.richard, A meeting can be started many times, i.e., a meeting can have multiple instances/occurrences. Each of these occurrences will have a unique UUID, and by using this UUID, you can differentiate between the sessions. To get the list if recordings for a meeting, you can use the Meeting ID, but it will give you the details for the last occurence. If you want to get the details for a particular occurence, then you need to use the Meeting UUID. You can use this API to get a list of all the ended meeting instances: [https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/pastmeetings](https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/pastmeetings) Let me know if this helps ---

OK - thanks for explanation of the meeting id - but how do I get the recordings from a particular instance of that meeting - feeding the uuid into /meetings/{meetingId}/recordings doesnt work - returns “code”: 3301, “message”: “This recording does not exist.” The meeting\_id in [recorded\_files] from get/userid/meetings doesnt correspond to any of the instance ids ---

OK - got it now Linkage is /report/users/{uid}/meetings -\>id to /past\_meetings/{id}/instances query /users/{uid}/recordings gives instance id in “meeting\_id” ---
