# NuData Captcha node

The NuData Captcha node displays a NuData captcha and collects the user's response for verification by the NuData risk-assessment service.

## Example

The following example shows how to use the NuData Captcha node to challenge sign-on attempts that return a medium risk score:

![Journey using the NuData nodes](nudata-nodes-journey.png)

* The [NuData Score node](nudata-score.html) returns the risk level for the sign-on attempt.

* A `Yellow` score outcome routes the journey to the NuData Captcha node.

* The NuData Captcha node displays a captcha and collects the user's response.

* The collected response is sent to NuData for verification before the journey continues.

* A `Next` outcome routes to the [NuData Update node](nudata-update.html), which reports the placement outcome to NuData.

* An `Error` outcome routes to the [Failure node](../failure.html).
