Zendesk Connector - Setup Form
1. Zendesk Admin access is required - please follow the steps here to find your access level
Because Zendesk allows IP filtering, this can block Fivetran from accessing your Zendesk org. The Fivetran setup test processes are run from the IP address
184.108.40.206 which is why it needs to be whitelisted in Zendesk.
