AS2 with Walmart
Question: Hi Louisa, I have just landed a contract to supply Walmart (woohoo!) but they want me to do EDI by using something called AS2. Do you know what AS2 is?
Answer: Hi Jim, thanks for the question. Yes, AS2 (Applicability Statement 2) is a specification intended to ensure the proper level of security and reliability for data transmitted over the Internet. Security is achieved by using digital certificates and encryption. In short AS2 is a secure way to exchange data over the internet, in this case the exchange of PO’s, Invoices and ASNs (Advance Ship Notices) between your organization and Walmart.
Document exchange requires more than just moving data over a wire. Because business documents are the basis not only of business planning and operations, but also the legal obligations between companies, the documents must be transferred securely, processed quickly and delivered reliably. AS2 is one of a small number of emerging standards that addresses these requirements and is becoming a very popular communication protocol used in EDI today. Walmart has been one of the great advocates of the adoption of AS2 in the EDI marketplace and many more have followed since.
