    Is there a way to ensure a field's uniqueness through Jotform?

    Asked by Brandon  on August 19, 2016 at 11:53 AM

    For instance, when a user submits their email, a webhook triggers and enters their data through our API. We need to be sure all emails submitted are unique. Can our webhook endpoint respond with a message that will then be displayed to the user? Alternatively, is there a way to ensure a field's uniqueness through Jotform?
