GET

Download FacturaE XML

Streams the FacturaE **3.2.2** XML for the invoice (B2G compliance), XSD-conformant with full tax breakdown. When the company has an active signing certificate the body is signed **XAdES-EPES** (Facturae v3.1 signature policy) and the filename is `.xsig`; without a certificate the XML is returned unsigned as `.xml`. The `X-Facturae-Signed: true|false` response header tells both cases apart. Draft invoices return 422 `invoice_not_emittable_for_facturae`.

GET

Download tax report file

Downloads the generated file for a tax report. Adds `X-Tax-Report-Hash` header for integrity verification.
