## Other responses

- `400`: - `invalid_request (request shape)` — The body, query, or headers failed validation, or a required header is missing. `details` has one entry per failing location, keyed by JSON pointer or header name.
- `401`: - `unauthorized` — API key authentication is missing or invalid.
- `403`: - `forbidden` — The credential is not permitted to perform this action on the resource. When the resource is a field of the request, `details` names that `field` and the `id` it received. - `forbidden (legal entity)` — The credential is not permitted to act for the selected legal entity. - `not_available` — Public API v2 is not yet available. Use [Public API v1](https://docs.slash.com/introduction) in the meantime. - `user_api_key_required` — The API key is scoped to a legal entity rather than a user. Every v2 request needs a user API key, created under Settings → API keys in the Slash dashboard, together with the `x-legal-entity` header.
- `404`: - `not_found` — No resource matches the identifier. When the identifier is a field of the request, `details` names that `field` and the `id` it received.
- `409`: - `conflict (idempotency key reused)` — A consumed `X-Idempotency-Key` was reused; the original response is not replayed.
- `429`: The request exceeded the applicable rate limit. The response body is plain text, not the error object; clients must not depend on its wording.
- `500`: - `internal` — Slash could not complete the request. Quote `referenceId` when contacting Slash support.
