AWS Transfer Family provides additional controls over AS2 message attributes

AWS Transfer Family announces new configuration options to control the attributes of inbound and outbound Applicability Statement 2 (AS2) messages. This update helps you ensure seamless compatibility with a broader range of your trading partners’ AS2 implementations, without requiring any changes on the partners’ side.

AS2 is a business-to-business (B2B) messaging protocol used across various industries, including healthcare, retail, supply chain and logistics. You now have greater control over the default attributes of your AS2 messages. For inbound messages, you can preserve the original filenames of files received from your trading partners and optionally enforce message signing requirements to ensure that only signed messages are received in line with your security needs. For outbound messages, you can maintain the content types associated with your AS2 payloads stored in Amazon S3, overriding the service default content type. These enhancements build upon the existing suite of AS2 interoperability features within AWS Transfer Family, enabling you to reliably exchange messages with your trading partners while maintaining the required message attributes.

The new configuration options for AS2 messages are available in all AWS Regions where the service is available. To learn more, visit the documentation. To get started with Transfer Family’s AS2 capabilities, take the self-paced workshop or deploy the AS2 CloudFormation template.
