In today’s interconnected business landscape, setting up secure data exchange channels is crucial for smooth operations and maintaining trust with partners. AS2 (Applicability Statement 2) provides a standardized method for secure and reliable B2B (business-to-business) communication over the internet. In this guide, we’ll walk through the steps to set up an AS2 connection, enabling seamless data exchange between trading partners.

1. Choose AS2-Capable Software

The first step in setting up an AS2 connection is selecting AS2-compatible software. Many commercial and open-source solutions support AS2, offering features such as encryption, digital signatures, and message integrity checks. Popular options include Axway AMPLIFY, Cleo Integration Cloud, and OpenText B2B Managed Services.

2. Obtain AS2 Certificates

AS2 relies on digital certificates to authenticate and encrypt data exchanged between partners. You can obtain AS2 certificates from a trusted Certificate Authority (CA) for your organization or you can generate self-signed certificates on your own and share them securely with your partners. These certificates will be used to establish secure connections and verify the identities of the sender and receiver.

3. Configure AS2 Settings

Once you have AS2-compatible software installed and certificates obtained, configure the AS2 settings within your software. This includes specifying your organization’s AS2 identifier, URL endpoints for sending and receiving messages, encryption algorithms, and digital signature preferences. Ensure that settings align with your trading partner’s requirements for seamless interoperability.

4. Exchange AS2 Information with Trading Partner

Exchange AS2 information with your trading partner to establish a connection. This information typically includes AS2 identifiers, URL endpoints, and public keys for encryption and digital signatures. Coordinate with your partner to ensure both parties have accurate and up-to-date information for successful communication.

5. Test AS2 Connection

Before fully deploying your AS2 connection for production use, conduct thorough testing to verify its functionality and compatibility with your trading partner’s system. Send test messages containing sample data and verify successful receipt and processing by your partner’s AS2 system. Address any issues or discrepancies encountered during testing to ensure smooth operation in a production environment.

6. Implement Production AS2 Connection

Once testing is complete and any issues resolved, implement your AS2 connection for production use. Begin exchanging real business documents, such as purchase orders, invoices, and shipping notices, with your trading partner over the AS2 connection. Monitor the connection for performance and reliability, and address any issues promptly to maintain uninterrupted data exchange.


Setting up an AS2 connection is indeed a critical endeavor for businesses involved in B2B communication.
