Dynamic links are a unique tool that Cal.com offers to simplify the appointment booking process. This is a feature that all Cal.com users have access to. To use this feature, all you have to do is type in Cal.com/your username plus the username of one or more people you want to connect with.
This will generate a custom booking page. The great thing about this page is that all the time slots that appear are only those in which all parties are mutually available. If you find that the dynamic booking link feature isn't working for you, it's probably because it hasn't been enabled within your profile settings.
