Triggers and actions 1 trigger · 22 actions

Returns every feed subscription in your The Old Reader account, with each feed's title, folders, site URL and icon.

- Update folder
Renames a folder in The Old Reader.

Renames a subscription or moves it between folders.
- 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.
Each app on its own

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.

Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
