I have a gotowebinar license and there is a great integration between lead pages and gotowebinar at https://www.leadpages.net/integrations
I also use zoom webinars which is an extension to zoom.us (http://zoom.us/) to enable it to do webinar registrations like gotowebinar - https://zoom.us/webinar. However there is no integration yet between lead pages and zoom webinars.
Would you be able to request the lead pages developers to work with the zoom webinar people to implement an integration?
I know quite a few people are starting to use zoom for webinars, and it would be a great lead pages integration to have :)
