New endpoints, tools and validation improvements, plus the compliance updates that ship
automatically on their legal effective dates, so your integration never has to chase them.
New endpoint
Download invoice attachments as a ZIP
POST /v1/extract/attachments pulls the embedded supporting documents (BG-24) out of a UBL, CII, XRechnung, Factur-X, or ZUGFeRD invoice and returns them as a single ZIP download: delivery notes, timesheets, the original order, whatever the sender attached. The attachment bytes are never opened on the server, and documents referenced only by external URI are left for you to fetch.
New
Show the technical details on the PDF
Set includeAdvancedProperties on the Factur-X and ZUGFeRD create endpoints to add an "Electronic invoice details" section to the rendered PDF, listing the technical XML properties a classic invoice layout leaves out: specification and business process identifiers, party identifiers and legal registrations with their scheme codes, electronic addresses, supporting document metadata, and line-level references. Handy when you want the human-readable page to mirror everything in the structured data.
New endpoint
Validation report as a PDF
Every validation can now return a polished PDF report of its findings, styled to match the web viewer, with clickable links from each finding straight to its field reference. Perfect for sharing a compliance check with a colleague or supplier.
Improved
Redesigned invoice PDF
Generated invoice PDFs were reworked to match the clean web viewer layout and typography, so the document you hand to a customer looks the part.
Compliance
Factur-X 1.0.9 / ZUGFeRD 2.5
Updated the Factur-X and ZUGFeRD conformance profiles (MINIMUM, BASIC WL, BASIC, EXTENDED) to the official Factur-X 1.0.9 / ZUGFeRD 2.5 validation artifacts, mandatory from 1 July 2026. Additive and backwards compatible: existing invoices keep validating and no integration changes are required.
New
UBL credit notes
Full credit note support for the UBL syntax on both create and validate, so you can issue and check UBL credit notes the same way you already do invoices.
New
Profile-aware validation
Validation now reads the document's declared CustomizationID and applies the matching rule set automatically: Peppol BIS 3.0, NLCIUS, PINT, and pinned XRechnung versions, each with its own profile rules on top of EN 16931.
New
Bring your own PDF
Pass a pdfUrl to the create endpoints and we embed the compliant XML into your existing PDF instead of rendering ours, so your hybrid Factur-X and ZUGFeRD invoices keep your exact design.
Improved
Richer invoice model
Added preceding invoice references, invoicing periods, and delivery details (BG-3, BG-14, BG-26), plus full ISO country and currency code coverage across every format.
New
Detailed validation report
Validation results are returned as a structured, BT-coded report: every finding maps to its exact EN 16931 business term, so you know precisely which field to fix rather than deciphering a raw rule id.
New tool
Embed, parse and extract
New endpoints to embed structured CII XML into a PDF/A-3 hybrid, parse an invoice back into JSON, and extract clean invoice data from an existing PDF or XML, making it easy to move between formats.
New
Multi-language invoice PDFs
Rendered invoice PDFs are available in English, German, and French, with the layout and labels localised for each language.
