To counteract the automated filling of your forms, we offer you the use of a so-called captcha in the form. This uses various techniques to ensure that automated entries by external systems are detected and rejected.
Google Cloud reCAPTCHA
Export column: captcha
Values: 0.0 .. 1.0
This is Google Cloud reCAPTCHA (reCAPTCHA Enterprise) and uses “scoring” to avoid user interaction.
Example:
Please note that the use of Google reCAPTCHA may have an impact on your privacy policy, as personal data may be exchanged with Google's servers.
In the export, you will receive values between 0.0 and 1.0, whereby values below 0.5 are considered critical and indicate that the data in the contact form was entered by a machine. We deliberately do not map the score determined by Google reCAPTCHA to boolean states so that you have the freedom to define your own rules for this.
Google reCAPTCHA v2
Export column: captcha
Values: true|false
This is Google reCAPTCHA version 2 with user interaction. In addition to the checkbox shown in the example, this also includes solving image tasks, etc.
Example:
Please note that the use of Google reCAPTCHA may have an impact on your privacy policy, as personal data may be exchanged with Google's servers.
Due to the interactive component of this widget, accessibility issues may arise that are conceptual in nature and cannot be resolved in this widget.
The values in the export can be used to check whether it was a regular user (true) or a machine input (“bot”): false.
