Redirect and iFrame Integration​

To integrate our identity verification process into your website, we highly recommend using an iFrame integration. This method keeps the user on your site throughout the verification flow, creating a seamless user experience. If an iFrame isn't suitable, you can also use a redirect to send the user to our web interface.

iFrame Integration​

To use an iFrame, embed https://ui.idenfy.com/ in your iframe tag with the authToken query parameter. You can get the authToken by generating an identification token. Unlike a redirect, an iFrame keeps the user on your site during verification.

To get started, simply embed the URL in an iframe tag and append the authToken as a query parameter.

caution
  • The allowfullscreen attribute is required if you are using our 3D liveness feature.
  • Do not use successUrl, errorUrl, or unverifiedUrl when generating the token, as this may break the iFrame flow.
  • The company's logo will not be displayed inside the verification session's UI.
  • After verification, you can close the iFrame and display the next page for your client.
<!DOCTYPE html>
<html>
  <body>
    <iframe
      id="iframe"
      allowfullscreen
      style="width:80%; height:800px;"
      src="https://ui.idenfy.com/?authToken=3FA5TFPA2ZE3LMPGGS1EGOJNJE"
      allow="camera"></iframe>

    <p id="display"></p>

    <script>
      window.addEventListener('message', receiveMessage, false);
      function receiveMessage(event) {
        console.log(event);
        // ...
      }
    </script>
  </body>
</html>

Query Parameters​

NameExample ValueDescription
authToken3FA5TFPA2ZE3LMPGGS1EGOJNJEAuthentication token for the verification session.
langenOptional. Forces a specific iFrame language (e.g., lang=en). Overrides the locale set during token generation.

Verification Status​

Monitor verification progress via the data object in the console.

PropertyValuesMeaning
statusAPPROVED / FAILED / UNVERIFIEDAutomated check result: approved, denied, or unfinished (timeout/cancel).
manualStatusAPPROVED / FAILED / WAITINGManual review result: approved, denied, or pending.
autoSuspected / manualSuspectedtrue / falseFlags whether suspicion was raised during automated or manual checks.

Redirect to Web UI​

To start a verification, redirect your client to:

https://ivs.idenfy.com/api/v2/redirect?authToken=authToken

Where authToken is the value generated from verification session.

Example: https://ivs.idenfy.com/api/v2/redirect?authToken=3FA5TFPA2ZE3LMPGGS1EGOJNJE

After the redirect, the user will see the iDenfy verification web UI.

Web SDK​

We often get asked if we provide a Web SDK. The short answer: No - and that’s by design.
Instead of adding the extra complexity of maintaining SDK packages, version upgrades, and dependency issues, we provide a superior integration option:

iFrame
  • With iFrame you get always up-to-date verification flow (no SDK updates required).
  • Seamless branding with full control over the surrounding page and layout.
  • Lighter integration — no additional packages, no breaking changes, no maintenance burden.
  • Future-proof stability — your integration won’t be affected by SDK lifecycle or compatibility issues.

This means you can integrate identity verification into your web app quickly, keep the user on your site, and avoid the long-term headaches of SDK management.
If an iFrame isn't suitable for your use case, you can also use a redirect to send the user to our web interface.
