Connect Harkbell to Zapier

Create an API key, paste it into Zapier and start Zaps from bookings, callbacks, calls and contacts, or write contacts and callbacks back.

Checked against the product on November 11, 2026

Harkbell's Zapier app starts a Zap when something happens in your business and can add contacts and callbacks from a Zap. It connects with one API key.

  1. In Harkbell, open Settings › Developers, create a key under API keys and copy it. See create an API key.
  2. Email hello@harkbell.com for the invite link to Harkbell's Zapier app and accept it in your Zapier account. The app is invite-only for now.
  3. In Zapier, choose Harkbell as the app for a trigger or an action.
  4. Paste the key when Zapier asks you to connect Harkbell.
  5. Choose a trigger such as New Booking, test it and map its fields into the next step.

What you can use

  • Triggers: New Booking, Booking Moved, Booking Cancelled, New Callback Request, Call Completed, New Booking Request, New Contact and Contacts Merged.
  • Actions: Create or Update Contact and Create Callback Request.
  • Search: Find Contact.

Zaps cannot change the diary

A Zap cannot move or cancel a booking, and it does not receive call recordings or transcripts. A call arrives with who, when, how long and a short summary, plus a link to read the rest in your dashboard. Nothing a Zap writes starts another Zap.

How do I stop a Zap?

Turn it off in Zapier, or revoke the API key in Settings › Developers. Revoking stops every Zap using that key at once. Subscriptions appear under Connected automations.

Can I use Webhooks by Zapier instead?

Yes. That needs a paid Zapier plan. Set up a webhook as in set up webhooks and point it at the Zapier address. Harkbell's own app is simpler: it checks every signature and can write back.

Where is the full list of fields?

In the developer reference, and in the Zapier integration page.
