Testing

Fourthline's platform is built to detect real faces. This means, by the nature of our business, we cannot provide dummy photos, files, or data for testing.

To test your Biometric Authentication solution:

1. Use the real faces and data of your colleagues to create test cases in the Sandbox environment.

2. To safeguard the privacy of your colleagues and their data, when you have finished testing, contact your Fourthline delivery manager to delete all testing data from the Sandbox.

Next steps

Continue with the API-only guide to configure your integration.
