- Convert CII XML to Factur-X
Converts a CII XML invoice into a Factur-X compliant PDF/A-3 with the XML embedded. The API generates a visual PDF rendering of the invoice and packages it with the source CII XML.
- Convert Factur-X PDF to CII
Extracts the embedded CII (UN/CEFACT Cross Industry Invoice) XML from a Factur-X PDF and returns it as a standalone XML file.
- Convert Factur-X PDF to UBL
Extracts the embedded CII XML from a Factur-X PDF and converts it to UBL (Universal Business Language) XML.
- Convert UBL XML to Factur-X
Converts a UBL XML invoice into a Factur-X compliant PDF/A-3. The API maps UBL to CII, generates a visual PDF rendering, and embeds the CII XML in the PDF/A-3 container.
- Create Factur-X Invoice
Builds a Factur-X invoice from structured header, party, payment, and line-item data, then returns a ready-to-deliver PDF/A-3b file.
- Embed XML Into PDF (Factur-X)
Takes a PDF and a CII XML and produces a Factur-X compliant PDF/A-3 with the XML attached as factur-x.xml. Use this when you already have both the visual PDF and the structured XML of an invoice and just need the hybrid wrapper.
- Extract Invoice JSON
Pulls invoice fields from a PDF into structured JSON, preferring embedded Factur-X XML when present and falling back to intelligent extraction when not.
- Extract Invoice XML
Retrieves machine-readable invoice XML from a PDF, returning embedded Factur-X XML directly or generating compliant XML when none is embedded.
- Render CII as PDF
Renders a CII (UN/CEFACT Cross Industry Invoice) XML document into a human-readable PDF. The output is a visual PDF, not a Factur-X hybrid file.
- Validate Factur-X Invoice
Checks whether a Factur-X invoice is structurally and semantically valid, including schema status, conformance level, and rule-level issues.
No trigger or action matches that. Ask your agent to add it: it reads the API documentation and builds what you describe.
