What is AS2?
AS2 is a protocol for sending EDI messages securely over the internet. Below you can read how it works and why retailers often require it.
AS2 (Applicability Statement 2) is a protocol for sending EDI messages securely over the internet. Messages are encrypted, signed and confirmed with a receipt (MDN). Many retailers and suppliers exchange their EDI traffic via AS2.
Sending messages securely
AS2 (Applicability Statement 2) governs how two parties exchange EDI messages directly and securely over the internet. The messages are encrypted and digitally signed, so no one can read along or tamper with them on the way.
After receipt, the recipient automatically sends back a signed receipt, the MDN (Message Disposition Notification). With it, the sender knows for certain that the message has arrived and is unchanged.
Where do you encounter AS2?
