AS2 (EDI transmission protocol)

Σύντομη απάντηση

A secure protocol for transmitting EDI messages directly over the internet, with encryption and delivery receipt (MDN).

Βασικά συμπεράσματα

  • Encryption - content is encrypted (digital certificates)
  • Digital signature - guarantees sender identity and integrity
  • MDN (Message Disposition Notification) - a signed delivery receipt proving delivery (non-repudiation)

What AS2 is

AS2 (Applicability Statement 2) is a communication protocol for securely transmitting EDI messages directly over the internet between trading partners, without a VAN intermediary. Heavily used by large retailers (e.g. Walmart mandated AS2 for its suppliers).

How it ensures security

  • Encryption - content is encrypted (digital certificates)
  • Digital signature - guarantees sender identity and integrity
  • MDN (Message Disposition Notification) - a signed delivery receipt proving delivery (non-repudiation)

AS2 vs VAN

A VAN (Value Added Network) is an intermediary routing messages (per-transaction cost). AS2 is a direct point-to-point connection (no per-message cost) but requires technical setup between partners.

How CRMconnect helps

CRMconnect supports AS2 for secure direct connections with partners that mandate it, managing certificates, encryption and MDNs - reliable EDI transmission and delivery proof, without per-transaction VAN costs.

Πραγματικό παράδειγμα

A supplier entering an international retailer's programme had to communicate via AS2. CRMconnect configured the AS2 connection with certificates and MDNs, and the ORDERS/DESADV/INVOIC exchange became direct, secure and per-message cost-free.

Συχνές ερωτήσεις

What is an MDN in AS2?+

Message Disposition Notification - the automatic, digitally signed confirmation that a message was received intact. It provides non-repudiation: proof the partner received the message, essential in contractual relationships.

AS2 or VAN - which do I choose?+

AS2 is a direct connection with no per-transaction cost but needs technical setup per partner. A VAN is an intermediary with per-message cost but simpler to connect to many partners. The choice depends on volume and partner requirements.

Is AS2 secure?+

Yes. It combines content encryption, digital signature (identity and integrity) and the MDN (delivery receipt), providing a secure channel with delivery proof over the public internet.
