Many organizations that employ electronic data interchange (EDI) in their business-to-business (B2B) transactions exchange EDI messages through the Applicability Statement 2 (AS2) protocol. EDI communications carried out over AS2 are sometimes called AS2 EDI. Known for being secure, cost effective and reliable, AS2 EDI is commonly used in automobile and manufacturing supply chains. It’s also popular in healthcare, retail and e-commerce industries.
