You can easily add video calls to your website using Daily.co's API, starting with their free plan. To embed a call, you'll need to paste specific code onto your site and replace the link with one created in your dashboard or programmatically. The call will be embedded on your site, allowing for customization of layout and design through CSS Grid, and can also be controlled programmatically using the REST API. With this integration, you can provide a seamless video calling experience to meeting guests directly from your website.
