Calendars and video

Google Calendar, Outlook and Office 365, Exchange and iCloud all connect for conflict checking, and Zoom, Google Meet, Microsoft Teams, Webex and GoTo attach a link automatically. The free plan connects one calendar and paid tiers go up to six per user, which is the hard ceiling.

Salesforce

Available from Teams up, writing scheduled events, routing form answers and no-shows back to lead, contact and opportunity records. Routing that looks up an account and hands the booking to its record owner is Enterprise only, and syncing routing responses needs an owner or admin.

HubSpot

The core CRM sync starts on Standard and logs meetings against the contact record. Teams adds selective sync so internal meetings stop filling the CRM, and mapping routing answers into custom properties leans on HubSpot workflows, which needs Professional on their side.

Marketo and Pardot

Existing marketing forms import into Calendly, then you add scheduling routes off visible or hidden fields and Salesforce ownership. This is the path for teams that want the booking to appear inside a demo request form they have already tuned rather than a second form.

API v2 and webhooks

A REST API with OAuth and personal access tokens covering scheduling, contacts and notetaker data. Webhook subscriptions cover invitee.created, invitee.canceled, no-shows and routing form submissions, need a paid seat, and are capped at 60 requests a minute until Enterprise raises it to 120.

n8n

A dedicated Calendly Trigger node listens for booking events and starts a workflow, and it uses the same webhook subscriptions, so a paid Calendly seat is a prerequisite. This is the cleanest route we know for turning a booking into enrichment and CRM writes.

Clay

Clay lists Calendly as a webhook integration on Launch and above, with no native actions published. In practice you point a Calendly webhook at a Clay webhook source, the booking lands as a row, and enrichment and routing happen from there.

Zapier and Make

Zapier is the general-purpose escape hatch and reaches several thousand apps from Standard up, which covers most of the tools with no first-party connector. It adds a hop and a subscription, so it is a fallback rather than the plan for anything high volume.

Embeds and the browser extension

Inline, popup and badge embeds drop the booking page into your site or a landing page, and the Chrome extension pulls a link into Gmail or LinkedIn without leaving the tab. Both are the pieces that make adoption easy for reps who will not learn a new tool.

What is missing

There is no self-hosted option and no open codebase, so the scheduling logic stays inside Calendly. Enrichment inside routing forms leans on Clearbit or ZoomInfo hidden fields rather than an open provider slot, and anything past the published connectors goes through the API or Zapier.
