# Cancel a pending approval (requester)

`POST /v1/approvals/{approval_id}/cancel`

## Request

- Base URL: `https://api.1claw.co`
- URL: `https://api.1claw.co/v1/approvals/{approval_id}/cancel`
- Auth: HTTP bearer

Withdraws a pending approval. Callable by the agent that requested it or
the human it was addressed to. First answer wins: if the approval was
already decided or expired, the existing record is returned unchanged
(200) rather than an error — the caller's next question is what the
answer was. A cancellation is delivered to webhook subscribers as
`approval.decided` with `decision: "cancelled"`, and audited as
`approval.cancelled`.

## Path parameters

- `approval_id` string, uuid, required

## Request body

- object
  - `reason` string

## Response `200`
