Captcha

Overview

The Captcha smart service generates a captcha image and the corresponding solution for validation use in Appian.  The smart service takes three inputs for the image document as well as three parameters that determine the complexity of the Captcha image:

• Document name
• Document parent folder
• Document description
• Add background
• Add fisheye
• Add noise

The outputs for the smart service are the Captcha image and the answer.
