## Response `200`

- object
  - `data` SimplifiedInvoiceEligibility, required: Result of checking whether an invoice can be issued as simplified (F2) under RD 1619/2012 art. 4.
    - `can_be_simplified` boolean, required: Whether the invoice can be issued as a simplified invoice (F2).
    - `must_be_complete` boolean, required: Whether the invoice must be issued as a full invoice (F1). It is the complement of `can_be_simplified`.
    - `reason_code` string, required: Code of the blocking reason when it cannot be simplified (`intra_community`, `reverse_charge`, `export_operation`, `client_deduction_required`, `over_absolute_limit`). Empty string `""` when it can be simplified.
    - `reason_message` string, required: Human-readable (Spanish) message of the blocking reason. Empty string `""` when it can be simplified.
    - `sector_limit` string, required: Absolute legal limit (EUR) above which a simplified invoice is not allowed, as a 2-decimal string.

## Other responses

- `400`: `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`).
- `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).
- `422`: Validation failed, or the invoice cannot undergo the requested state transition (e.g. marking an already-paid invoice as paid, or editing an issued invoice — use a corrective instead). The `error.param` field identifies which input is invalid, if any. Issuing or annulling an invoice can also be rejected with `verifactu_not_eligible`: either a field of the invoice does not fit its billing record, or — only when the company has VeriFactu enabled in NO VERI*FACTU mode — it has no usable signing certificate (`error.subcode: signing_certificate_unavailable`; `error.param` is `certificate`, `representation` or `system_certificate`, depending on what is missing); in both cases the invoice stays exactly as it was.
- `429`: Rate limit exceeded. Retry after the duration in `Retry-After`.
- `500`: Unexpected server error.
