# Cancel a bulk job

Cancels an in-flight bulk job: drains its still-queued (pending) child jobs and refunds the quota held for exactly those drained children. Children already completed, failed, or in progress are untouched and keep their charge. Idempotent — cancelling an already-terminal job (completed, failed, or cancelled) is a no-op that returns 200 with the job's real, unchanged status and refunds nothing.

**DELETE** `/v1/bulk/{id}`

## Parameters

- `id` (path, string, required)

## Responses

### 200 — Bulk job after the cancel attempt. `status` is `cancelled` when the job was in flight, or its real terminal status when it had already finished.
- `id`
- `status`
- `total`
- `completed`
- `failed`
- `created_at`
- `completed_at`
- `total_credits_charged`
- `total_billed_bytes`
- `estimated_credits`
- `webhook_url`

### 401 — Unauthorized. The request carried no valid credential, and no work was
performed. The unified `Error` envelope carries one of the codes below
in `error.code`; match on the code, never on the prose.

- `invalid_api_key` — a bearer API key was presented and rejected:
  unknown, revoked, expired or malformed. The bearer-only operations
  (`/v1/webhook-deliveries*` among them) also return it when no
  `Authorization` header is sent. `GET /v1/account` is the exception
  to "malformed": it returns `invalid_api_key` only for a key that
  starts `sk_test_` or `sk_live_` and is unknown, revoked or expired.
- `unauthorized` — the `Authorization` header is absent or malformed on
  an operation that also accepts a dashboard session (the dual-auth and
  billing operations). `GET /v1/account` also returns it, for no
  `Authorization` header and for any bearer value that does not start
  `sk_test_` or `sk_live_` (that value is checked as a dashboard
  session token).

Not retryable as-is: supply a valid API key first.
