Notes
  • The authentication result is determined based on option settings and threshold values, returning either approved or rejected.
  • Recommended faceImage specifications: 960 x 720
  • How to check submissionId: Log in to the dashboard, go to Settings > Liveform URL, and complete the ID Check process. Once ID Check is approved, you can find the submissionId data in the User Management menu > Submission List in the dashboard.
    • The final status of the ID Check must be approved.
  • API Key Information: A separate API Key is required from the existing liveform API Key. You can check your Add-on API Key under Getting Started.
