    Check whether a (scheme, value) pair is a recognized Peppol document type identifier. Requires EINVOICING_PEPPOL_CODELIST_DIR (see `list_participant_id_schemes`). Searches all entries regardless of state, so a historical (deprecated or removed) document type is still reported as found.

  • identify_and_extract_pdf

    Identify a hybrid PDF/A-3 invoice and extract its embedded XML. Reads XMP metadata to identify whether the file is a Factur-X/ZUGFeRD hybrid PDF (see `PDFEmbedder.identify`; the XMP schema itself is verified against a real sample, but a PDF from a different producer may not carry the same XMP shape), then extracts the embedded XML attachment by trying `CANONICAL_HYBRID_PDF_FILENAMES` in turn. Args: pdf_base64: Base64-encoded PDF/A-3 file bytes. Returns a dict with the `PDFEmbedder.identify()` fields (`is_hybrid_pdf`, `conformance_level`, `document_type`, `document_filename`, `version`) …

  • peppol_directory_search

    Search the Peppol Directory for registered participants. Public, unauthenticated search (no relation to SMP lookup). At least one of q/participant/name/country/doctype must be supplied.

  • peppol_get_service_endpoint

    Fetch the AS4 endpoint for a Peppol participant's document type. Resolves the SMP hostname via DNS, then fetches service metadata for *document_type_id*. If the SMP returns a redirect, the result's `redirect_url` is set and `endpoint_url` is None; callers must not follow more than one redirect hop (SMP 1.4.0 §3.2). Args: identifier: Peppol participant ID or adaptable national identifier. document_type_id: Peppol document type identifier URN (default: BIS Billing 3.0 invoice). environment: "production" or "test".

  • peppol_lookup_participant

    Check whether a business is registered on the Peppol network. Performs a DNS-over-HTTPS U-NAPTR lookup followed by an SMP service-group request to determine registration status and the list of supported document type identifiers. Args: identifier: Peppol participant ID ("<scheme>:<value>") or a bare national identifier this server knows how to adapt (e.g. a VAT number, if a national identifier adapter is configured). environment: "production" or "test".

  • peppol_send

    Send a UBL/CII invoice to a Peppol participant via AS4. Looks up the recipient's AS4 endpoint (SMP), builds the ebMS3/AS4 envelope, and transmits it using the supplied signing credentials. Args: invoice_xml_base64: Base64-encoded UBL or CII invoice XML. recipient_identifier: Peppol participant ID or adaptable national identifier of the receiver. sender_id: Peppol AP identifier of the sender. certificate_path: Path to the PEM-encoded signing certificate. private_key_path: Path to the PEM-encoded private key. private_key_password: Optional password for the priva…

  • resolve_peppol_dns

    Resolve the SMP hostname for a Peppol participant via DNS only. Performs the raw U-NAPTR (SML) lookup without fetching the SMP service group, useful for diagnosing whether a participant is registered in the SML independently of SMP reachability. Args: identifier: Peppol participant ID or adaptable national identifier. environment: "production" or "test".

  • validate_eusr_report

    Validate a Peppol End User Statistics Report (EUSR) document. Runs XSD structural validation, then Schematron business rules (requires the ``[xslt2]`` optional extra). Args: report_xml_base64: Base64-encoded EUSR XML document.

  • validate_mls_message

    Validate a Peppol Message Level Status (MLS) document. Runs the bundled MLS Schematron rules (requires the ``[xslt2]`` optional extra). No bespoke MLS XSD exists — full UBL 2.1 XSD validation is out of scope. Args: mls_xml_base64: Base64-encoded MLS (UBL ApplicationResponse-2) XML.

  • validate_tsr_report

    Validate a Peppol Transaction Statistics Report (TSR) document. Runs XSD structural validation, then Schematron business rules (requires the ``[xslt2]`` optional extra). Args: report_xml_base64: Base64-encoded TSR XML document.
