How to add people to lists on Klaviyo via Zapier

Hi @Leafage, 

Thanks for joining our Community and thanks for the great question! You are correct in that we do not currently have a Calendly integration, but you can use Zapier for this connection. 

1. The details for connecting Zapier and Calendly can be found here
2. You can also use custom code which utilizes Calendly’s APIs. You can read about this here (this page describes how Calendly’s webhooks can be used for event creation). Your code would need to send a custom event to Klaviyo each time the Calendly webhook notifies you that an event has been created/scheduled (you would use Klaviyo’s Track API for this).

Let me know if you have other questions on this topic. Have a great day!
