AS4 (Applicability Statement 4) was developed for ebXML messaging services by OASIS (the Organisation for the Advancement of Structured Information Standards).
A Closer Look At AS4:
AS4 is a communication protocol that has been designed specifically to facilitate the exchange of business data over the internet which was developed for ebXML messaging services by OASIS (Organisation for the Advancement of Structured Information Standards)
AS4 is HTTP-based, with messages sent over AS4 having a specific format that is handled by AS4 software. Both successful and unsuccessful message transfers receive a receipt allowing the sender to know if the transfer has succeeded.
- AS4 can be used by any organisation that wants to send and receive documents electronically in safe, secure and encrypted transmissions.
- Suppliers in the public sector and Peppol network would find it particularly useful as Peppol only supports AS4 now.
- Increasingly used in markets that use a service-oriented architecture for B2B messaging, for example utilities, retail and health sectors.
- AS4 can be a replacement for customers that currently uses AS2/SFTP/FTP clients.
- Designed to push and pull data securely and reliably over the internet
