Connect Cal.com

Connecting Cal.com turns bookings into call events in Klarvyn — stitched to the visitor’s ad journey, including cancellations, reschedules and no-shows.

Connect

1. In Cal.com, go to Settings → Developer → API keys and create a key (cal_live_…).

2. In Klarvyn, go to Settings → Integrations, open the Cal.com card and paste the key. Self-hosting Cal.com? Enter your instance’s API URL in API base URL (self-hosted only) — otherwise leave it blank.

3. Click Connect Cal.com. The key is validated before anything is stored.

4. In Cal.com Settings, click Add Event Types and select which event types should create call events — Klarvyn registers one webhook per selected event type, automatically.

5. Make a test booking on a selected event type — it appears as a call on the contact within seconds.

What flows in

• Bookings on selected event types become call events, with the event-type name as Calendar Name, appointment time and duration.
• Cancellations, reschedules and no-shows update the original call — no duplicates — and show as timeline cards on the contact.

Good to know

• Nothing is tracked until you select event types — connecting only lists them; step 4 is not optional.
• Team event types can require a paid Cal.com plan. If Cal.com refuses a webhook for a team event type, Klarvyn tells you exactly which ones aren’t being tracked.
• Best attribution: embed Cal.com on your own site with the Klarvyn tracking script — bookings then stitch to the visitor’s full journey. Bookings from a plain cal.com link fall back to email matching.
• Cal.com doesn’t pass UTM parameters natively — attribution relies on the embed stitching (or email matching), so prefer the embed.
• Disconnect removes every webhook Klarvyn registered in Cal.com; recorded calls are kept.
