# Cancel pending (and optionally running) migration jobs for an entity

> Operational queue cleanup. Sets `status='cancelled'` on every pending
migration job for the entity, and (optionally) every running job. A
cancelled job is distinct from a failed job: monitoring should not
treat it as an error, and the audit reason is recorded in the job's
`errors[]` JSONB so the cancellation context is preserved.

Common use cases:
- The entity is being abandoned for a fresh entity, so the queue is contaminated.
- A buggy bulk-submit needs to be drained before a clean re-run.
- The runner is being redeployed and in-flight jobs should not be claimed mid-update.

**Body parameters.**
- `reason` (optional string) -- audit note stored in each cancelled job's
  `errors` array. Defaults to `"admin_cancelled"`.
- `include_running` (optional boolean) -- also cancel `running` jobs.
  Default `false`. Risky for live runs (cancels in-flight work); use only
  when you've confirmed nothing meaningful is in flight.

**Scope:** `migration:write`.




## OpenAPI

````yaml /openapi.yaml post /entities/{entity_id}/migration/jobs/cancel
openapi: 3.1.0
info:
  title: Arcus ERP Public API
  version: 1.0.0
  description: >
    Arcus ERP public REST API. Designed for external integrations and data
    migration.


    **Authentication.** Bearer token (API key) via the `Authorization` header.

    Format: `Authorization: Bearer ark_live_ent_<code>_<random>` (or
    `ark_test_*` for sandbox).

    API keys are issued per-entity in **Settings > Developers > API Keys**.


    **Entity scoping.** The entity is encoded in the API key prefix; routes are
    flat

    (e.g. `/v1/accounts`, `/v1/orders`, `/v1/products`). A small set of platform
    endpoints

    (migration, reconciliation, events, webhook endpoints, API keys) use the

    `/v1/entities/{entity_id}/...` form -- those are noted in their tags.


    **Key capabilities.**
      - Related-resource hydration via `?expand[]=` (see `x-arcus-expand` on each resource).
      - Cursor-based pagination (`starting_after` / `ending_before` / `limit`).
      - Idempotency via the `Idempotency-Key` header.
      - Webhook events for asynchronous notification.
      - Conditional requests / ETag for cache validation.
