We want to reduce the amount of effort it takes to join a room for new users by making the workflow more seamless. In order to do that we will allow a user's First Name, Last Name and Email Address to be supplied with the room link or embed code.

When the user lands on the signup page they will see a slightly different view with fields that are pre-filled using the query string values.

Technical Spec

Room Link Format



Embed Code URL Format



<iframe src="" sandbox="allow-scripts allow-same-origin allow-top-navigation allow-forms allow-popups allow-pointer-lock allow-popups-to-escape-sandbox" allow="camera;microphone" width="1024" height="768"></iframe>


  • firstname: The attendee's first name.

  • lastname: The attendee's last name.

  • emailaddress: The attendee's email address.

  • autofill: This parameter determines whether or not to show the new design.
