Applicability Statement 2 (AS2) is a specification for data exchange, to perform the task of sending and receiving data via a secure connection. It works as a kind of “envelope,” in which data is embedded, so that it is possible to send it using the HTTP-protocol. It is a quick and direct transfer, without using a mailbox. AS2 is able to transmit every kind of document and it’s suited especially for the traditional EDI transactions. The data to be sent will be prepared by internal systems and will be transferred via an AS2 communication software.
