Does Conferencing still work in these new modes?

Yes, Conferencing can be provisioned as usual, using the conferencing options.

Services like Zoom, WebEx and GoTo all work the exact same way.

Microsoft Teams and Google Meet can still be used, but not via the integrated profile_id option any more but instead they need to be connected separately. This is because connections via Free/Busy and No Access Mode calendars do not have permissions to write to the users calendar, and so cannot reach those conferencing options.

This means that integrated is not a valid option when creating an event in these calendars; instead you can either:

1. Pass the profile_id special value default. Cronofy will resolve which conferencing service to use for the event.
2. Connect Google Meet or Microsoft Teams as a separate service, and provision using those profile_ids directly.

This means there should be little to no development needed to use conferencing with Calendar Access Modes if you are already using Conferencing through Cronofy. You can learn more about our conferencing integrations in the Conferencing Services documentation.
