Video/Streaming Services That Allow for Third Party Paywalls (like TNEW)

Hello!

In the the new COVID-19 pandemic world, we have been dipping our toe into digital content. We have been using Vimeo (I believe) for our Summer online Shakespeare production, but it is a by donation event, not a traditional paid event.  As the new season approaches, we are looking an continuing with digital content but would obviously like to implement a paid aspect for live streaming and/or video on demand.  

So, like most, I am excited to see what the new Gated Digital Content hub through TNEW will allow us to ticket our online and digital events.  However,  it appears that some of the usual video/digital streaming services (Vimeo, Youtube, etc) explicitly state vaguely allude to in their Terms & Conditions or User Agreements that the use of third party paywalls (like TNEW) is prohibited.  So I was curious what other organizations have been using (or plan to use) to host video and live streaming events while still being able to use TNEW/Tessitura for ticketing.  

This is such a new thing for us that I am unsure - beyond the Vimeos and Youtubes of the world - where to start.  I would be grateful for any suggestions.

Thanks!
