Integrate calendars other than Outlook/Google

[AJungstand]

I am looking for an integration (synchronization, not just import) of my Zoom calendar with other calendars. Ideally it would be a bi-directional synchronization via webdav. Does anyone have a solution for this. Background: Neither Google nor Outlook fulfill the necessary data protection requirements and couldn't be used.
Many thanks in advance

This may help - first is enabling bi -directional sync. https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0058782

and here is the list of integration compatibility to zoom.

Many thanks for your help and sorry for coming back so late.
Nevertheless it's not the solution I'm looking for. All the offered integrations don't fulfill the necessary data protection requirements. A webdav based solution would work, like many other calendars providing. For me the most important point is the integration in my mail client (Thunderbird) and/or my cloud services (Nextcloud).

Best regards, AJ

Unfortunately, no further ideas have been given. If you follow jrmango's suggestion, only Office365, Exchange and Google Calendar will continue to be offered. It is a great pity that Zoom does not offer support for standard calendar protocols (webcal; ical). Or have I overlooked something here?

For me, this may mean looking for a video conferencing tool that works with common standards for calendar integration.

Meanwhile I had an exchange with the customer support on this topic. Unfortunately this has not lead to a solution. The only recommendation I got was to develop my own integration - which isn't really a solution because it's beyond my capacity. So far nothing new.

NextCloud would definitely be a good option to add... 

[AJungstand]

I completely agree with FTBug - from a technology point of view it's the same as what I asked for, because Nextcloud is able to integrate standard webcal (via webdav). This means that with a minimal change to the Zoom servers, millions of customers could be satisfied.

For bi-directional synchronization of your Zoom calendar with other calendars via WebDAV, you may need a third-party service like Nextcloud, ownCloud, or EteSync, which support CalDAV/WebDAV protocols. Zoom does not offer native WebDAV sync, but you can integrate it with a self-hosted or privacy-focused calendar that meets data protection requirements. Look for calendar sync tools that bridge WebDAV with Zoom’s API or use an intermediary service like Cronofy for secure calendar synchronization.

Thanks for the hint regarding Conofy. I Think it's not a solution. Registering a Cronofy account requires a Google or Microsoft 365 account. Both is data protection critical and would make Cronofy itself insecure with regard to the protection of personal data. And if  I'd use Google I would not need Cronofy, because Google calendar integrates perfectly with Zoom. I still hope that Zoom will find a way to integrate the tiny piece of software for WebDav (which is the only standardised calendar exchange: RFC 4791). Other video conference tools have this in place since years.
