EDI Protocol Comparison AS2 AS4: Understanding the Key Differences

Electronic Data Interchange (EDI) is a process for exchanging business info between companies. It uses messages and specific systems, replacing paper transactions. For EDI, various protocols like HTTP, SFTP, SOAP, REST, and others exist. This blog focuses on AS2 and AS4 in our EDI Protocol Comparison AS2 AS4. We will explore each protocol, highlighting their differences, advantages, and disadvantages.

What is AS2?

AS2 (Applicability Statement 2) reliably and safely transmits data. It’s designed for B2B document exchanges, outperforming protocols like HTTP. AS2 enhances security and allows real-time acknowledgments and transactions. This increases exchange efficiency, making it a standard for transferring EDI and other data.

For message encryption between partners, AS2 uses HTTPS. It transmits files as ‘attachments’ in standard messages. AS2 handles all file types, offering message signing for authentication.

AS2 improves traceability by requiring Message Disposition Notifications (MDNs). These confirm successful transfers and full message delivery. It provides several MDN options, including synchronous and asynchronous returns.

However, most ERP systems lack built-in AS2 capability, necessitating separate integration. This requires detailed knowledge and can lead to extensive troubleshooting without expertise in AS2 functionalities.

What is AS4?

AS4 (Applicability Statement 4) is the latest protocol, advancing beyond AS2. It’s an interoperability protocol that streamlines web services for B2B data exchange and integration. Being an open standard, AS4 prevents vendor lock-in. It handles diverse payloads like legacy EDI, binary, and XML, enhancing versatility.

The Messaging Service Handler (MSH) sets up AS4 exchanges with remote stations. This occurs on both sending and receiving ends.

Send and Receive operations in AS4 follow a P-Mode configuration. This setup manages the protocol, business info, error handling, reliability, and security.

AS4’s foundation in SOAP and Web Services distinguishes it from AS2. Its compatibility with standard environments is higher as many organizations use these technologies internally. This makes extending these technologies to external integration straightforward.

AS4’s frequent use in EDI projects comes from its secure and reliable message exchange. It uses WS-Security features like message encryption, digital signatures, acknowledgments, retry mechanisms, and supports large attachments.

Final Thoughts: Choosing the Right Protocol in EDI Protocol Comparison AS2 AS4

In summary, AS4 offers a cutting-edge, robust solution for EDI messaging. It ensures the necessary security, reliability, and flexibility for electronic document exchanges. While AS2 remains popular and supported, it suits simpler messaging needs or existing AS2 infrastructures. However, upgrading to AS4 is advisable, as it brings more benefits.
