Conversion tracking for Cal.com
Cal.com is the open-source scheduler, and the important difference is that it can be self-hosted. If it is, you own the database and the webhooks and there's no paid tier gating anything — which makes it the most tractable scheduler in this cluster. If you're on the hosted version, it behaves much like Calendly: embed type decides how the click ID gets in, and the booking webhook is the reliable event.

- If bookings already carry click IDs and reach your platforms, the work is done.
- Self-hosted Cal.com gives you database access, so reconciliation is a query rather than an export. Use that before buying anything.
