UPDATE AS OF AUGUST 22, 2022:

Webhook endpoint validation is not yet released and verification is not yet required. However, please be aware that these changes will be coming. Once enabled, you will need to validate your webhook endpoint before Zoom will use it to send events. Please monitor the Changelog for updates.

Once enabled, Webhook endpoints will require initial manual validation before Zoom will send events to them. Endpoints will also be validated every 72-hours using a challenge-response check. This will be required for new webhooks created after changes have been enacted. See Validate your webhook endpoint for details.

There is a new way to verify that webhook events are sent by Zoom. The previous method, using a webhook verification token, will be deprecated and replaced with the new method, once enacted. We recommend that you replace your webhook verification token logic with the new logic described in the Verify webhook endpoints documentation.
