What you can do with Calendly webhooks

Start an agent

Calendly events can start a new agent run. For example, an agent that researches everyone who books a Calendly call.

Resume an agent

An agent can pause until the Calendly event it needs arrives, for up to 90 days, and costs nothing while it waits.

Message an agent

Calendly events can land in a running agent's conversation, so it acts on them with full context.

Events you can receive from Calendly

Calendly sends events like invitee.created and invitee.canceled, and your agent can filter on any of them.

View all events

Example

An agent that researches everyone who books a Calendly call

import { webhook, webhooks } from "@trigger.dev/sdk";


export const calendly = webhooks.endpoint.define({
  id: "calendly",
  source: webhooks.calendly(),
});


export const calendlyEvents = webhook({
  id: "calendly-events",
  endpoint: calendly,
  filter: "event.event == 'invitee.created'",
  onEvent: async ({ event }) => {
    // Start, resume or message your agent with the event
    console.log(event);
  },
});

Verified for you

webhooks.calendly() checks the Calendly-Webhook-Signature header on every request. Bad requests are rejected before anything runs.

Filter before anything runs

Only the Calendly events you care about start a run. Filtered webhooks use no compute.

See every delivery

Every webhook is recorded with its payload, headers and the agents it reached, so you can debug it and replay it.

Get started

  1. 1

    Set up the agent

    Copy the starter prompt into your coding agent, like Claude Code, Cursor or Codex. It creates a Trigger.dev project and adds the webhook endpoint. Prefer to write it yourself? Start from the example above.

  2. 2

    Add the webhook in Calendly

    Deploy your project, or run trigger dev, and the endpoint appears on the Webhooks page of the Trigger.dev dashboard with its URL. Add that URL in Calendly's webhook settings and pick the events you need. The endpoint's Copy setup prompt button gives your coding agent the exact steps.

  3. 3

    Add Calendly's signing secret

    Copy the signing secret from Calendly. Then on the endpoint's page in the Trigger.dev dashboard, choose Set signing secret and paste it in, so Trigger.dev can check every request really came from Calendly.

  4. 4

    Try it

    Send a test event from Calendly, or use the endpoint's Test tab. It appears on the endpoint's Deliveries tab, with the agents it reached.
