Accepted only while the request is `info_requested`. Up to 2000 characters. Reference: https://docs.api.corpx.com/ib/referencia/accounts/create-limit-request-message ## Authentication - `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer `, where token is your auth token. ## Request ### Path parameters - `accountId` (string, required) — Account identifier. - `requestId` (string, required) — Limit request id. ### 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. - `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 (`..`, ES256 or PS256) over `METHOD\nPATH?QUERY\nTIMESTAMP\nIDEMPOTENCY_KEY_OR_EMPTY\nX_CONTENT_SHA256`. ## Response ### 201 Message stored. ## Errors ### 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. ### 422 Unprocessable Entity Error Empty message or message longer than 2000 characters. - `errorCode` (string, required) — Stable machine-readable code.
