We are wanting to stop duplicates submissions using authenticator and contact list trigger in the following manner:
Check if email is NOT on contact list. If not, they may take the survey. Then, the email is added to the contact list, meaning they would fail auth if trying again with the same email.
What is the best way to achieve this? Is JavaScript required for this or can I do it with the graphical interface?
