PDP interoperability requires more than technical connectivity. It requires a controlled compliance architecture integrating PEPPOL AS4, PPF APIs, authentication mechanisms and auditable evidentiary chains.
Key requirements:
• Traceable API exchanges
• Controlled access and timestamp consistency
• Secure communication layers and documented infrastructure
• End-to-end auditability and compliance governance
D2F Compliant supports organizations through interoperability design, compliance validation and implementation readiness.
