**Description** I am calling the endpoint `/metrics/meetings/{meetingId}/participants/qos` and passing in a UUID. Most times I receive a status code 200 and everything is as expected. However, sometimes, I receive a status code 404. This seems to be caused by the UUID containing a forward slash. **Error** { “code”: 3001, “message”: “Meeting does not exist: HKEpw/xERiKX/PKxMl39A==.” } **Which App Type (OAuth / Chatbot / JWT / Webhook)?** Oauth **Which Endpoint/s?** `/metrics/meetings/{meetingId}/participants/qos` **How To Reproduce (If applicable)** ``` GET https://api.zoom.us/v2/metrics/meetings/HKEpw/xERiKX/PKxMl39A==/participants/qos?page_size=10&type=past Headers: Authorization: Bearer Body: undefined ``` **Additional context** I’m using the Requests package via Python to access the API, so any related suggestions would be great. ---

Hey @curtis, If the meetingUUID has a slash `/` in it, you must double [url encode](https://www.urlencoder.org/) it. So `HKEpw/xERiKX/PKxMl39A==` will become: `HKEpw%252FxERiKX%252FPKxMl39A%253D%253D` Thanks, Tommy ---

Hi @tommy, Thanks for the suggestion. I tried double URL encoding the UUID for another meeting that has a `/` within the UUID, but that still returned `"code": 3001`. Original UUID: `dJzN/qMQT9yfKOwVhiNofQ==` Double encoded UUID: `dJzN%252FqMQT9yfKOwVhiNofQ%253D%253D` **Query** ``` GET https://api.zoom.us/v2/metrics/meetings/dJzN%252FqMQT9yfKOwVhiNofQ%253D%253D/participants/qos?page_size=10&type=past Headers: Authorization: Bearer Body: undefined ``` **Result** ``` { "code": 3001, "message": "Meeting does not exist: dJzN/qMQT9yfKOwVhiNofQ==." } ``` Any thoughts on what might be happening here? ---

Hey @curtis, Are you still getting this error? Do you get the same error when you query the Meeting ID instead of the UUID? Additionally, was this a one-time meeting or part of a recurring series? Let me know when you have a chance! Thanks, Will ---

@will.zoom – thanks for the response. I’m still getting the same error with that UUID (as well as others). The Meeting ID for that specific meeting is `691808998`, returns the following response when I submit the Meeting ID instead of the UUID: ```auto GET https://api.zoom.us/v2/metrics/meetings/691808998/participants/qos?page_size=1&type=live Headers: Authorization: Bearer Body: undefined ``` ```auto { "next_page_token": "", "page_count": 0, "page_size": 1, "participants": [], "total_records": 0 } ``` For context, I’m testing these error cases through the _Send a test request_ section in the API documentation. ---

Hey @curtis, In taking a look at that most recent ID, it looks like that was a one-time meeting from a while back. A [scheduled](https://support.zoom.us/hc/en-us/articles/201362413), non-recurring meeting ID (also known as a one-time meeting ID) will expire 30 days after the scheduled date, which is likely why you’re not seeing any results for this meeting. You can read more about this here: > **[Meeting ID](https://support.zoom.us/hc/en-us/articles/201362373)** > > Overview > The meeting ID is the meeting number associated with an instant or scheduled meeting. The meeting ID can be a 10 or 11-digit number. The 11-digit number is used for instant, scheduled or r... Thanks, Will ---
