Snippet
<script src="https://<host>/embed.js" async></script>
<div id="cal-inline-embed"></div>
<script>
Cal("init", { origin: "https://<host>" });
Cal("inline", {
elementOrSelector: "#cal-inline-embed",
calLink: "my-user/intro",
config: { theme: "light" }
});
</script>Theming
Query params on the embed URL:
theme=light|darkprimaryColor=<hex>locale=en|es|...timeZone=America/Los_Angeles
These override the event type's defaults for the embedded session only.
Message passing
The iframe posts messages to the parent on lifecycle events: __cal.init, __cal.booking-successful, __cal.booking-cancelled, __cal.booking-rescheduled.
