AWS Transfer Family AS2 now supports receipts of MDNs asynchronously

AWS Transfer Family now supports receiving Message Disposition Notifications (MDNs) asynchronously for messages sent to trading partners over Applicability Statement 2 (AS2). This enables you to migrate your AS2 workflows to Transfer Family while maintaining interoperability with your trading partners, regardless of their message processing times or network requirements.

Organizations across healthcare, life sciences, retail, manufacturing, and supply chain sectors depend on Transfer Family for secure AS2-based data exchange with trading partners and regulatory bodies. You can now send AS2 messages while requesting MDNs asynchronously over a separate TLS connection, ensuring compatibility with partner AS2 systems that have extended processing times or high latency. With this launch, Transfer Family supports both synchronous and asynchronous MDN requests, enabling you to migrate AS2 workflows to AWS without impacting your partner integrations.

This capability is available in the majority of AWS regions where AWS Transfer Family is offered. For the full list of supported regions, visit the AWS Capabilities tool in Builder Center.
