Zoom account keeps requesting to be reauthorized

This authentication issue occurs due to a known limitation in Zoom's API. Zoom does not support users being logged into their account on multiple devices simultaneously.

Zoom's developer support team has documented this limitation here.

When you use your Zoom account on multiple devices, Zoom automatically invalidates previous authentication tokens, causing repeated reauthorization requests. This affects BusyCal's integration with Zoom meetings and calendar sync.

Solutions

Recommended approach: Use your Zoom account in BusyCal on only one device to avoid authentication conflicts.

Alternative workaround: If you need Zoom integration on multiple devices, you can create separate Zoom accounts for each device, though this requires managing multiple accounts.

We encourage you to provide feedback directly to Zoom requesting they improve multi-device support for third-party calendar integrations.
