3160426 - Can we add Captcha field to a public trigger in workflow accelerator.


To prevent spam bots to use our public form we would like to use a captcha functionality in our workflow.


A captcha functionality is not available. You could use a a gateway in your diagram with a check for a specific value to prevent the form to be abused by spam bots.

E.g. Add a gateway with the question "Which color has the grass?" and check if the user provided "green". If it was green proceed with the process if not end the process.
