AS2 Connector Release Notes - Mule 4

Support Category: Premium

Anypoint Connector for AS2 (Applicability Statement 2) is a specification about how to transport data securely and reliably over the internet. Security is achieved by using digital certificates and encryption.

Mule runtime engine (Mule) supports the AS2 protocol through the Anypoint Connector for AS2 (AS2 Connector). AS2 Connector enables trading partners to transmit and receive AS2 messages with EDI-X12, EDIFACT, XML, or binary payloads.
