AS2 Mailbox: HTTP Tab

For example, your AS2 name (AS2-From) and your trading partner's AS2 name (AS2-To) as well as the Subject and Content-Type of the documents to be transferred. 

Default Value

You can assign a default value for each of the headers defined on the AS2 Host: HTTP tab. (See AS2 Host: HTTP Tab.) Unless an overriding value is specified within the command in an action, these default values are used. (See AS2 Checklist: item 5 for the AS2-From value, item 6 for the AS2-To value, and item 14 for the default Content-Type value.) 

At a minimum, the following Headers must always be specified in order to properly send AS2 messages:

• AS2-From - the alias of the sender of the AS2 message.
• AS2-To - the alias of the receiver of the AS2 message. 
  Note: The AS2-From / AS2-To fields are determined and agreed upon as part of the initial setup of the trading relationship. These fields could be company-specific, such as DUNS number, or could simply be an agreed-upon identification string. The AS2-From / AS2-To combination is case-sensitive and must be unique across all hosts defined in your system, since this combination is used to determine into which Inbox messages are stored when received from remote hosts.  
• Subject - identifies the message and is returned in the human-readable section of an MDN, if requested.
• Content-Type - the format of the message being sent and is used by the sending and receiving applications to properly assemble and parse the message. Currently supported content types (in the pull-down menu) are:
  • EDIFACT
  • X12
  • XML
  • Binary
  • Plain Text
  • EDI Consent
  Note: Entering a value for the Content-Type header is optional. If Content-Type is not specified or if multiple payloads are attached in the message, the Content-Type is detected based first on file content and then the file extension. Detectable types include application/edifact, application/edi-x12, application/edi-tradacoms, application/xml (text/xml), application/pdf, application/msword, application/x-msexcel, application/rtf, application/zip, image/bmp, image/gif, image/tiff, image/jpeg, text/plain, text/html, and video/mpg.
