# Close this tenant's access to the account

POST https://client.api.corpx.com/v1/accounts/{accountId}/close

Removes this tenant's access to the account. The HTTP response is the
same whether another CorpX tenant still operates the bank account or
this tenant is the last one: the caller cannot tell.

Humans need `tenant_manager` or `admin`. Credentials need the
`accounts.close` scope (legacy `api2/write` still passes). A `viewer`
cannot close.

The row is not deleted. It becomes `status=closed` with
`status_source=tenant_close`. Already closed in this tenant returns
the same 200 without a second email.

When this tenant is the last one still operating the account, the
raw settlement-bank balance must be zero (`total`, `available` and
`locked`). Any non-zero value returns **422** `account_has_balance`
and leaves the row active. A zero exclusive close emails MT support
and then closes the row.

Binding to another tenant's account, a missing account, or a
`suspended` row is always **404** `account_not_found` — never
`403 tenant_mismatch`.

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Path parameters

- `accountId` (string, required) — Account identifier.

### Headers

- `X-Tenant-Id` (string, required) — Tenant context used for authorization and routing.
- `Idempotency-Key` (string, optional) — Optional client-generated idempotency token (recommended for safe retries).
- `X-Request-Timestamp` (string, required) — Unix seconds. Required on the signed host; tolerance is 300s either way (`403 request_timestamp_skew`).
- `X-Content-SHA256` (string, required) — Lowercase hex SHA-256 of the body. An empty body hashes the empty string, so the header is always present. Mismatch returns `400 body_hash_mismatch`.
- `X-Request-Signature` (string, required) — Detached JWS (`<protected>..<signature>`, ES256 or PS256) over `METHOD\nPATH?QUERY\nTIMESTAMP\nIDEMPOTENCY_KEY_OR_EMPTY\nX_CONTENT_SHA256`.

## Response

This tenant lost access. The message is identical on both internal paths.

- `accountId` (string, required)
- `message` (string, required)
