Hello,  
I am trying to fetch participants in past meetings from my end. For a recurring meeting, I can get instances of it using the endpoint:  
{{baseUrl}}/past\_meetings/:meetingId/instances

And then I use the result to get participants in an instance using this endpoint:  
{{baseUrl}}/past\_meetings/:meetingId/participants

But because the first endpoint returns meeting UUID not Id, I use this endpoint:  
{{baseUrl}}/past\_meetings/:meetingUUID/participants

It works fine, but for some meeting UUIDs like this, it does not work:  
array (  
‘uuid’ =\> ‘/fTyq/xPT4KokFvwRTr+lw==’,  
‘start\_time’ =\> ‘2025-02-10T07:45:06Z’,  
)

I think this is because of slashes in the uuid. So, How can I solve this?  
Thank you

Hi,

Coud you try double encoding the meeting UUID and see if it helps?
