The `Location` header contains the canonical URL of the new contact. - `400`: The request is syntactically malformed — e.g. an unknown query parameter, an integer parameter with non-numeric value, or a value outside the documented range. `parameter_unknown` with `subcode` `retired_active_profile_header`: the retired `X-Active-Profile` header was sent; the company goes in the path. `parameter_invalid_format` on `Factuarea-Version`: the header is not a `YYYY-MM-DD` date. `unsupported_api_version`: the `Factuarea-Version` date is not a supported version. - `401`: Missing or invalid API key. - `403`: The request is authenticated but not allowed: the API key lacks the required scope (`insufficient_scope`), the plan does not include the public API or this feature (`addon_not_active`, `feature_not_available_in_plan`), or the module is not available with a test key (`module_not_available_in_sandbox`). `company_inactive`: the company in the path is deactivated; reactivate it to operate. - `404`: The requested resource does not exist or belongs to another company. `profile_not_found`: the company in the path does not exist, is not in the API key scope or belongs to the other environment (live or test). - `409`: The request conflicts with data that already exists or with a request running at the same time. `resource_already_exists` with `subcode` `tax_id_already_exists`: another contact of the company already has that fiscal identity; `details.existing_resource_id` is its identifier. `resource_conflict`: another request was reserving identifiers for the same kind of record at that moment and this one could not complete its reservation. Nothing was written; send the request again after a few seconds. - `422`: Validation failed. The `error.param` field identifies which input is invalid. `idempotency_key_reused`: the `Idempotency-Key` was already used with a different body; send a new key or the same body. `invalid_param_format` on `Idempotency-Key`: the key must be 1 to 255 printable ASCII characters. - `429`: Rate limit exceeded. Retry after the duration in `Retry-After`. - `500`: Unexpected server error. --- [API](https://skmtc.dev/factuarea/apis/factuarea-public-api.md) · [All operations](https://skmtc.dev/factuarea/apis/factuarea-public-api/llms.txt) · [OpenAPI document](https://skmtc.dev/factuarea/apis/factuarea-public-api/revisions/718e77934422?raw)
