# Cancel a limit increase request

POST https://client.api.corpx.com/v1/accounts/{accountId}/limit-requests/{requestId}/cancel

Cancels a request that is still `pending_review`. Any other status
is `409 limit_request_closed`. Sends `limit_request.updated`.


Reference: https://docs.api.corpx.com/ib/referencia/accounts/cancel-limit-request

## 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.
- `requestId` (string, required) — Limit request id (`lr_` + ULID).

### Headers

- `X-Tenant-Id` (string, required) — Tenant context used for authorization and routing.
- `X-Acting-Document` (string, optional) — CPF of the human performing the operation. Required on cashout routes when the credential enforces a transaction PIN.
- `X-Acting-Ip` (string, optional) — Real IP of the end user, for integrator credentials calling on their behalf. This is the IP evaluated against `cashoutSourceIps` — without it the check would see your server's IP. Ignored for delegated credentials, where the connection IP is already the right one.
- `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

### 200

The cancelled request.

- `id` (string, required)
- `status` (enum, required)
  - Allowed values: `pending_review`, `approved`, `refused`, `cancelled`
- `operation` (enum, required)
  - Allowed values: `pix_out`, `ted_out`, `boleto`, `internal_out`
- `window` (enum, required)
  - Allowed values: `single_transfer`, `daytime`, `nighttime`, `monthly`
- `currentLimitBrl` (double, required) — Effective ceiling when the request was opened. 0 when the account had none.
- `requestedLimitBrl` (double, required)
- `justification` (string, required)
- `identifier` (string, required)
- `createdAt` (datetime, required)
- `approvedLimitBrl` (double, optional, nullable) — Ceiling actually applied. Null until approval. May differ from `requestedLimitBrl` when the reviewer adjusts it.
- `decisionMessage` (string, optional, nullable)
- `effectiveAt` (datetime, optional, nullable) — When the new ceiling starts. Null means it was applied immediately.

## Errors

### 404 Not Found Error

`limit_request_not_found`.

- `errorCode` (string, required) — Stable machine-readable code. See `ErrorCode` for the known values.
- `message` (string, required) — Human-readable explanation (pt-BR). Presentation only; may change.
- `docs` (string, optional) — Link to this code in the public error catalogue.
- `requestId` (string, optional) — Gateway request id. Quote it when contacting support.
- `details` (map from string to any, optional) — Optional machine-readable context for the specific `errorCode` (for example `kind` on `identity_verification_monthly_limit_exceeded`, `maxBytes` on `payload_too_large`, `attemptsRemaining` on `facetec_attempts_exhausted`). Keys are documented per operation; absent when the code carries no extra context.
- `partner` (ErrorResponsePartner, optional) — Raw error from the settlement bank, when the failure came from it. Diagnostic only.

### 409 Conflict Error

`limit_request_closed`.

- `errorCode` (string, required) — Stable machine-readable code. See `ErrorCode` for the known values.
- `message` (string, required) — Human-readable explanation (pt-BR). Presentation only; may change.
- `docs` (string, optional) — Link to this code in the public error catalogue.
- `requestId` (string, optional) — Gateway request id. Quote it when contacting support.
- `details` (map from string to any, optional) — Optional machine-readable context for the specific `errorCode` (for example `kind` on `identity_verification_monthly_limit_exceeded`, `maxBytes` on `payload_too_large`, `attemptsRemaining` on `facetec_attempts_exhausted`). Keys are documented per operation; absent when the code carries no extra context.
- `partner` (ErrorResponsePartner, optional) — Raw error from the settlement bank, when the failure came from it. Diagnostic only.

## Types

### ErrorResponsePartner

Raw error from the settlement bank, when the failure came from it. Diagnostic only.

- `code` (string, optional)
- `message` (string, optional)
- `field` (string, optional) — Field the partner pointed at, when any.
