In our new platform, we've redesigned the embed experience in just five quick steps:
1). Log-in into your FreeBusy account https://freebusy.io/en/signin
2). Create a new meeting or select a previously set-up meeting
3). Get the lines of code for your website. Expend the meeting Name tab and click on the Embed Code button.
4). Embed into your website. Copy the code in the prompted window.
5). Go to your website editor view. If your website allows embedding via IFRAME, paste the embed FreeBusy HTML code when prompted. Now follow your website instructions for how to embed code from other applications.
