What field reveals the UUID that I should use API calls for scheduled_events?

I asked this 9 days ago but never got clarity on which field I am supposed to use.

If I do this:

curl --request GET \
  --url "https://api.calendly.com/scheduled_events?organization=https://api.calendly.com/organizations/DERERCVFDYL7OLC&min_start_time=2025-01-01T00:00:00Z&max_start_time=2025-06-30T23:59:59Z" \
  --header 'Authorization: Bearer eyJraWQiOiIxY2UxZTEzNjE3ZGNmNzY2YjNjZWJjY2Y4ZGM1YmFmYThhNjVlNjg0MDIzZjdjMzJiZTgzNDliMjM4MDEzNWI0IiwidHlwIjoiUEFUIiwiYWxnIjoiRVMyNTYifQ.eyJpc3MiOiJodHRwczovL2F1dGguY2FsZW5kbHkuY29tIi234523zUtYmQxMy03ZTBhNWIwNDk2MjciLCJ1c2VyX3V1aWQiOiJBSEhCWE5MVElEQVJMWkU3In0.jsvcK0mRkCdIF87BJ7UxVaHfQDWClDc-QEIl-PyYuXYVm95wDIWR4r-_Xw7IwLp_18Q-amd8BGmsa5deb0P9qw' \
  --header 'Content-Type: application/json'

There is no field called “UUID”. But I’m supposed to use a UUID if I then call the API for “invitees”. 

Again, this is the JSON that comes back. It does not have a field called “uuid”.

Any thoughts about why I am not seeing a UUID? I’ve tried every ID in the return that looks like ID and yet I’m still yet every API call returns with “Resource Not Found.”

If I go here:

https://developer.calendly.com/api-docs/2d5ed9bbd2952-list-events

The page never mentions a UUID. I cannot find a reference to the UUID anywhere in any of the descriptive text, and yet it is listed as a required parameter when asking for the invitees.

I want to find a UUID and then make a call like this:

curl --request GET \
  --url "https://api.calendly.com/scheduled_events/8pv58mskifkj5st9o6m2qqde74/invitees" \
  --header 'Authorization: Bearer eyJraWQiOiIxY2UxZTEzNjE3ZGNmNzY2YjNjZWJjY2Y4ZGM1YmFmYThhNjVlNjg0MDIzZjdjMzJiZTgzNDliMjM4MDEzNWI0IiwidHlwIjoiUEFUIiwiYWxnIjoiRVMyNTYifQ.eyJpc3MiOiJodHRwczovL2F1dGguY2FsZWferdXBNQ2356hOS1kYzQxLTRlMzUtYmQxMy03ZTBhNWIwNDk2MjciLCJ1c2VyX3V1aWQiOiJBSEhCWE5MVElEQVJMWkU3In0.jsvcK0mRkCdIF87BJ7UxVaHfQDWClDc-QEIl-PyYuXYVm95wDIWR4r-_Xw7IwLp_18Q-amd8BGmsa5deb0P9qw' \
  --header 'Content-Type: application/json'

But that comes back with “Resource Not Found.” 

I have tried to use everything in the JSON that looks like a UUID, but all of it comes back with “Resource Not Found.”

Where is the UUID?
