We host regular webinars. Some folks are able to watch them live, and once the webinar is over we can pull reports that show who watched and for how long. This is important when awarding education certificates for nurses. If a registrant watches the recording later, however, I can't pull the same information. I'll get "Sally Jones" registered for the on demand webinar and that "guest" watched the webinar for 58 minutes, but I can't connect "Sally Jones" to "58 minutes watched." Anyone have a workaround?

I am working on an integration for my company where we have many recruiters that set up webinars for virtual campus tours. We utilize webinars for these events and I am building an integration using webhooks. This will allow for webinar details to send a webhook payload to an endpoint that will create a Campaign for us in Salesforce.

We need to be able to pass over some custom fields/data about the event that are not relevant to the end-user directly, but determine how the end result gets routed and configured in Salesforce.

For example, we need to pass over a field that tells us the type of recruiting effort this is going to be. Is this going to be OnCampus, or Online.  Rather than having a custom question where we ask the registrant this, we are trying to set it up in a way where the specific webinar they register for has a hidden hardcoded type so they aren't selecting anything on the registration form, but it's a value that is sent over with it and stored in the webinar record. Think of this as adding a hidden input field on an HTML form. It would have a name and a value.

Now, I am aware of the scheduling tracking fields, but these look to be account level specific with limits of 10 per account. I need something more at the webinar/meeting level. A good place for this could even be the custom questions section on the registration form with a type of "hidden" where we just provide a name and a value, that way its already part of the "form" and sent over with submission.

Perhaps as an end-user, something like this exists but I am not aware of it or its not currently enabled.
Does anyone have any ideas? 

I'm planning to make a webinar event, my first choice is to choose zoom webminar, but I have some questions that until now I haven't found a solution even after I read the zoom documentation and tried the trial
My problem is:
1. how to limit the participants who can join the webminar based on the email that has been registered in the admin (import CSV)?
2. How can each participant registered in the admin (csv import) get a unique link for each participant? because I've tried the trial and found that the link sent to all participants is the same, and every user who has logged in or has logged in can join the webminar even though the email is not registered as a participant.
3. If the link for all participants is the same, then my first question is very decisive, because I don't want the link given to be shared publicly, and I don't want to do manual approval, because 500 participants is not a small number.
4. How can I make sure that when I finish importing participant data in CSV format, Zoom does not automatically send the webminar link to registered participants?

If we are hosting a webinar and want the host and/or cohost to be able to share their screen and have the attendees see both the shared screen and the 4 panelists, what is the best view to use? Follow host or Gallery View? Or is there some other view that we should be using? Thanks for your help!

At the start of the webinar, I used three slides of PowerPoint to switch between "image + music" and "video " for the opening.

But sometimes when I broadcast and switch them at the same time, the PowerPoint freezes.

How can this be avoided? Is it a problem with the specifications of the PC?
