Once you have fetched a valid session token, you can navigate the user to Verisoul’s ID Check URL to complete the verification process.

​
ID Check URL

The ID Check URL is: https://app.{env}.verisoul.ai/ where {env} is:
  • prod for production
  • sandbox for sandbox
The ID Check URL accepts the following query parameters:
​
session_id
string
required
The session token obtained from the Verisoul API
​
redirect_url
string
The URL encoded string to redirect to after the verification is complete (default: https://verisoul.ai)
​
lng
string
Optional language parameter to customize the instructions (default: en) See Localization for more details

​
On Completion

Once the ID Check session is complete, the user will be sent to the redirect_url configured in the query parameters. By default, ID Check redirects to https://verisoul.ai. The completed redirect URL will contain the following parameters:
​
session_id
string
The session ID used for the verification
​
success
boolean
Whether the verification was successful
​
error_message
string
Present only if success is false, contains the reason for failure

For web applications, you can redirect the user to the FaceMatch URL:

function redirectToIDCheck(sessionId) {
  const redirectUrl = encodeURIComponent(window.location.origin + '/verification-complete');
  const idcheckUrl = `https://app.prod.verisoul.ai/?session_id=${sessionId}&redirect_url=${redirectUrl}`;
  
  window.location.href = idcheckUrl;
}
If your user is on desktop, Face Match will automatically recognize this and display a QR code so that the user can complete the verification on their mobile device.

​
Error Handling

Error messages can include:
  • invalid_session_id: The session token provided is expired or invalid
  • session_id_not_found: No session token was provided
  • failed_to_get_camera_permission: The user did not agree to give the browser camera permissions
  • failed_to_complete_face_scan: The user was not able to complete the face scan process
  • failed_to_process_id_scan: This user was not able to complete the identity document capture process
  • failed_to_collect_device_data: The user’s device/network was not able to send device data
  • liveness_check_failed: The user did not pass liveness verification
It is recommended to parse the error_message and prompt the user to restart the ID Check process. To let a user retry, you will need to fetch a new session token.

​
Next Steps

After the user completes the ID Check verification, you can verify and enroll the user to implement uniqueness checks or authentication.
