# Cal.com

> Event types, schedules, availability slots, bookings, calendars, and webhooks.

Cal.com is included in Archal's environment catalog. Use it in a sandbox for event types, schedules, availability slots, bookings, calendars, and webhooks.

|                 |                                               |
| --------------- | --------------------------------------------- |
| Environment ID  | `calcom`                                      |
| Transport       | REST and MCP                                  |
| State           | JSON                                          |
| Contract        | `archal.environment-state.calcom` version `1` |
| Channel         | Preview                                       |
| Curated samples | 5                                             |

Preview means the environment is included for testing, but its upstream coverage is incomplete. Verify the operations your test depends on.

## Compatibility boundary

**Local catalog validation:** All five published samples passed. Checks cover the state contract, relationships, artifact hash, secret scan, and size limit.

<Note>
  Local catalog validation is not hosted proof. Archal checks current certification, reset, and isolation evidence before admitting new sandboxes. Use the authenticated environment catalog for live availability.
</Note>

* Time-zone and organization-admin behavior require operation-specific verification.

## Curated starting states

List the five samples with `archal sample list calcom`. Each sample is a versioned starting state with a representative read, mutation, expected diff, reset expectation, and verified artifact hash.

<AccordionGroup>
  <Accordion title="Cal.com bookable event">
    Expose one user, schedule, and 15-minute event type with a valid future slot.

    **Sample ID:** `calcom.bookable-event.v1`

    **Category:** `minimal`

    **Starting state:** 3 records across `eventTypes`: 1, `schedules`: 1, `users`: 1

    **Supported surface:** Stateful users, event types, schedules, availability, and booking workflows.

    **Required capabilities:** `state.read`, `state.load`, `state.reset`, `rest.bookings`

    **First read:** `GET /v2/event-types`. Expected result: HTTP 200.

    **Representative mutation:** `POST /v2/bookings`. Expected result: HTTP 200, 201, 204.

    **Mutation input**

    ```json theme={null}
    {
      "attendee": {
        "email": "maya.chen@example.test",
        "name": "Maya Chen",
        "timeZone": "America/Los_Angeles"
      },
      "eventTypeId": 5898555,
      "start": "2027-01-15T18:00:00.000Z"
    }
    ```

    **Expected diff:** changes include `bookings`. Exact match required: no. Hosted promotion must observe every listed path after the provider-native mutation; dynamic provider ids and timestamps are excluded from exact matching.

    **Expected reset:** restores loaded sample.

    **Known limits**

    * Time-zone and organization-admin behavior require operation-specific verification.

    **Start this sample**

    ```bash theme={null}
    archal sample show calcom.bookable-event.v1 --raw > archal-calcom-bookable-event.json
    archal state validate calcom archal-calcom-bookable-event.json
    archal session create calcom \
      --state calcom=archal-calcom-bookable-event.json
    ```

    **Inspect the raw state**

    ```bash theme={null}
    archal sample show calcom.bookable-event.v1 --raw
    ```

    The packaged JSON artifact is `samples/states/calcom/bookable-event/state.json` and is 7,114 bytes. The CLI verifies SHA-256 `fba93b07769939b26fb221877c9c650437119e5e83030d10b18760a72282d83e` before printing it.

    Catalog validation: **Passed**. Hosted availability is determined by Archal's live certification and admission system, not this static page.

## Use custom state

Start from a sample when possible. For custom state, inspect the contract with `archal environment describe calcom`, then validate the file before creating a sandbox:

```bash theme={null}
archal state validate calcom state.json
```

Loading state replaces the current collections and establishes a new reset baseline. See [Starting state](/sandboxes/starting-state) before replacing state in an existing sandbox.
