Overview
The Invoice.xhub API creates, reads and validates electronic invoices across 37 countries: XRechnung and ZUGFeRD in Germany, Factur-X in France, FatturaPA in Italy, KSeF in Poland, myDATA in Greece, Peppol BIS 3.0 wherever it applies — and PDF everywhere.
What the API does
The basics
Every endpoint lives under https://service.invoice-api.xhub.io and needs an
API key. Documents are passed in and returned Base64
encoded throughout — XML and PDF alike.
Which countries and formats a key may actually call is governed by
entitlements (e-invoice:{country}:{format}:parse and relatives). Without
the matching entitlement the API answers 403.
