This feature must be enabled by Zoom and each additional vanity URL must follow the same guidelines detailed above to be approved by Zoom.
Note: Enabling multiple vanity URLs will change the SP Entity ID field. Admins should update this value as needed to avoid SP Entity ID errors. If you are using the Zoom app in Okta, the SP Entity ID cannot be changed. To modify this value, you will need to create a custom app in Okta.
