- 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.

Questions
Clientary and Factur-X by InvoiceXML, answered
What can start an automation from Clientary?
Any of Clientary's 3 triggers in the catalog, including New Expense, New Invoice and New Staff. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Factur-X by InvoiceXML when something happens in Clientary?
Any of Factur-X by InvoiceXML's 10 actions, including Create Factur-X Invoice, Convert CII XML to Factur-X, Convert Factur-X PDF to CII and Convert Factur-X PDF to UBL. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Factur-X by InvoiceXML to Clientary?
Factur-X by InvoiceXML has no triggers in the catalog today, so automations start in Clientary. If you need the other direction, ask: your agent reads Factur-X by InvoiceXML's API documentation and adds it.
Do I have to build a connector for Clientary or Factur-X by InvoiceXML?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Clientary and Factur-X by InvoiceXML without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
