We are registering webinar participants through CiviCRM event pages, so each participant becomes a CiviCRM contact associated with one or more webinar-type events. Some of these webinars are paid events. Is there a good way to restrict access to a webinar based on the information in CiviCRM? We'd like to be able to restrict access so that only paid participants can access the paid webinars, even if someone else gets the webinar link, for instance.
We have not settled on a webinar platform yet, though we are leaning towards Zoom. Another possibility is Blackboard/Collaborate.
Any thoughts/suggestions would be welcome.
