Hi @Navey,
Thanks for your patience so far!
Unfortunately, there is no such functionality with the Webex APIs as of now which can solve this purpose.
But just to re-illustrate your use-case, first of all this capturing screenshot functionality is not part of Webex. It's basically a device functionality, be it a Mobile device or, a computer.
And, even though Webex supports Webhooks for certain operations - but those operations are its own, like Sending a Webex Message, Receiving Webex Message, Starting a Webex Meeting, or, Adding someone over a Webex Space, etc and all these operations are currently supported through Webex API too.
Webex Webhook would not be able to track the external operations outside of its scope - like capturing a screen shot through a device.
So, to make it available with Webex Webhook, first "capturing a Screenshot" needs to be available through API so that once it happens, then Webex Webhook can read its JSON Response and gets triggered for further action.
And, I don't think there would be any plan for Webex build an API for "Capturing screen shot" randomly from any device.
But all these discussions really makes sense if you're asking about taking a screen shot from a Cisco Device like here - https://help.webex.com/en-us/article/iwxb18/Videos-and-snapshots#task_854E3756EB4D19A3AFB9FE7EC6DF3B8B
And, I believe at times - it's critical too to understand if someone took a snapshot of a live Meeting, the Host of the meeting should know about it.
Since in this case, the snapshot is getting captured by the functionality of a Webex device itself, here the API and the corresponding Webhook can be considered!
I'd say in that case, it'd be possibly a new feature request.
Let me check with our Device Engg. group internally about this feature and get back to you soon.
Regards!
