CAPTCHA
A CAPTCHA (short for Completely Automated Public Turing test to tell Computers and Humans Apart) is a challenge-response test in computing intended to ensure that a response is not generated by a computer. Typically, the computer presenting the test asks a random question that a person can answer but that is very difficult for a computer.

In business automation
On lead forms and login pages, a CAPTCHA distinguishes a person from a bot submitting fake records. In automation, it appears when a public form connects to a CRM or when an agent tries to complete a screen that requires human verification.
Examples
These examples illustrate a possible workflow. Adapt the connections and rules to your own systems.
Blocking fake leads on a form
A website form creates a record in the CRM after submission. Without a challenge, the pipeline can be flooded with automated inquiries. Add a CAPTCHA before record creation, and run the automation only after human verification succeeds.
Relevant tools
- Clerk
- Login flows can include a bot check; verify that the step does not block a legitimate user after a correct password.
What to check
- Adding a CAPTCHA to every internal interface slows employees down and does not stop a bot that already has an API key.
