# Restore an excluded bank feed transaction

> <Note>Required API key scope: `accounting:write`</Note>

Undoes an exclusion: flips `excluded -> unreconciled` and clears the
exclusion audit columns (`excluded_at` / `excluded_by` /
`exclude_reason`). The line becomes visible to reconciliation math and
matchers again.

**Status flips allowed:** `excluded -> unreconciled` ONLY. A `matched`
or `reconciled` line returns 409 (`bank_transaction_not_restorable`).

**Idempotency:** restoring an already-unreconciled line is a 200 no-op
(`already_unreconciled: true`).

**No GL postings occur.** No request body.




## OpenAPI

````yaml /openapi.yaml post /accounting/bank-transactions/{bank_transaction_id}/restore
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.
