Update An Organization Webhook

Updates a webhook configured in an organization. When you update a webhook, the `secret` will be overwritten. If you previously had a `secret` set, you must provide the same `secret` or set a new `secret` or the secret will be removed. If you are only updating individual webhook `config` properties, use "[Update a webhook configuration for an organization](/rest/orgs/webhooks#update-a-webhook-configuration-for-an-organization)."
