Cancel one upcoming or past time off booking.

CharlieHR MCP tools: https://cotlet.dev/docs/mcp/charliehr.md

MCP tool: `charliehr_write → cancel_time_off_booking`

Access: write. Confirm: waits for the user's OK before it runs.

Does what the bin icon does on the Time tab. Upcoming bookings can be cancelled by their owner or an approver, and the approvers are notified. Past bookings need a line manager, team lead or Admin. Cancelling past sick leave always needs approval. Where Cancellation Requests are on, a cancellation can wait for the approver. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `booking_id` | string | yes | Id from list_time_off_requests |
| `notes` | string | no | Reason shown to the approver |

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
