To use TrueSample Device Fingerprint in your questionnaires you will need to provide a range of parameters that are sent to TrueSample. These parameters will contain the API authentication detail along with some custom parameters you need to adjust based on the desired functionality. For your comfort, the parameters can be set in a separate expression form, which will allow you to change their values without having to interact with the inclusion-script itself. The communication to the API itself happens in an ordinary question form with a hidden input. The process itself will happen in the background, so it is ideally used e.g. as the welcome screen of your survey, as the request can take a few seconds, depending on the internet connection speed. The values as described in the Fraud Check chapter are represented inside the dataset and can be used further for filtering or other actions.
