VeriFactu reports the real AEAT environment

5 November 2026 — On the production API, VeriFactu records always go to the real AEAT, automatically. The configuration said otherwise: it returned environment: "sandbox" and auto_transmit: false from two per-company values that never decided anything. It now returns what actually happens.

• Configuration — GET /v1/companies/{company}/verifactu/config returns environment (production or sandbox) and auto_transmit from the Factuarea instance, not from your company. On the production API they are production and true.
• Records — every record returns the same environment: the AEAT it is submitted to.
• environment filter — on the record list and the stats it now filters: the environment of the instance returns every record and any other value returns none. Before, it was ignored.
• Deprecated in the update — PATCH /v1/companies/{company}/verifactu/settings still accepts environment and auto_transmit so your integration keeps working, but they have no effect and the response returns the real values. They will be removed on 7 December 2026: stop sending them.
• Test mode — VeriFactu is not available in test (403 module_not_available_in_sandbox): nothing is recorded or sent to the AEAT. In live there is no AEAT test environment to choose. See Test mode.
• MCP tools — get_verifactu_config returns the same values, update_verifactu_settings accepts the two deprecated fields without effect, and search_verifactu_records and get_verifactu_stats filter by environment in the same way.

What reaches the AEAT has not changed: only what the API reports about it.
