Captcha

The availability of functionality depends on the license and may not be available in all deployments.

The captcha component is a Google widget whose purpose is to allow submission of data only filled in by a human.

Component properties

The component can be placed multiple times on the form, and its display can be conditioned on meeting a criterion.

Illustration 1. Captcha component displayed on the form

Providing the value of the captcha placed on the form is always mandatory - verification will be positive when the "I'm not a robot" checkbox is selected and optionally other actions are performed (imposed by Google).

Illustration 2. In the example the "I'm not a robot" checkbox was not selected, which caused a validation error message to be displayed

Component validation occurs after the image is correctly selected. The component stores 3 types of states: too long a wait time after verification - "expired", positive verification - "ok" or negative - "noOk". Interactions on the form may depend on the component's state.
