I am trying to send an alert to a Zoom Room. I could not find a lot of documentation on how to do this, but did find the Update e911 Digital Signage api, which I believe is meant to do this.

The request is going through to the Zoom API and returning an event id as expected. However, the Zoom Room display is not showing the alert.

How To Reproduce
Send a PATCH request as noted above, nothing changes in the room.

Hey @bjv211

Could you verify that you’ve enabled the digital signage setting in your account:


Yes, the rooms are enabled with digital signage, which plays during the non-meeting times.
