To programmatically set the email of the user, add a query parameter to the iframe src, e.g. "https://seedblink.fornax.ai/?email=user@mail.com". The iframe uses postMessage to send messages from the iframe to the parent website when feedback starts and finishes processing. It will send the messages 'FEEDBACK_PROCESSING' and 'FEEDBACK_GENERATED' respectively. To add an event handler for these messages, you can do the following: <script> window.addEventListener('message', event => { if (event.origin === '[https://seedblink.fornax.ai'/]https://seedblink.fornax.ai'/) { if (event.data === 'FEEDBACK_PROCESSING') { // code } if (event.data === 'FEEDBACK_GENERATED') { // code } } }); </script></div><script src="https://d3e54v103j8qbb.cloudfront.net/js/jquery-3.5.1.min.dc5e7f18c8.js?site=663a17fd3c305cdbcb754344" type="text/javascript" integrity="sha256-9/aliU8dGd2tb6OSsuzixeV4y/faTqgFtohetphbbj0=" crossorigin="anonymous"></script><script src="https://cdn.prod.website-files.com/663a17fd3c305cdbcb754344/js/webflow.schunk.36b8fb49256177c8.js" type="text/javascript"></script><script src="https://cdn.prod.website-files.com/663a17fd3c305cdbcb754344/js/webflow.schunk.b9cf373bdd1e3b60.js" type="text/javascript"></script><script src="https://cdn.prod.website-files.com/663a17fd3c305cdbcb754344/js/webflow.547479fa.37190b3e7b7532f6.js" type="text/javascript"></script> <!-- Google Tag Manager (noscript) --> <noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-NPXT223" height="0" width="0" style="display:none;visibility:hidden">
