4.2.5.6. AS2 Gateway Out

With an AS2 Gateway, outgoing messages are transmitted using an AS2 connection. 

AS2 (Applicability Statement 2) is a specification about how to transport data securely and reliably over the Internet. Security is achieved by using digital certificates and encryption.

The following fields should be defined in order to configure your AS2 access:

 From 

 Babelway source server. 

 To 

 AS2 ID of the server that receives outgoing messages. Provided by your partner. 

 Type 

 MIME/TYPE used to transfer the AS2 message to your partner. Possible values are : 

"edi", for the content type "application/EDIFACT". 

"x12", for the content type "application/EDI-X12". 

"eco", for the content type "application/edi-consent". 

"xml", for the content type "application/XML". 

"bin", for the content type "application/ octet-stream". 

DEFAULT is "bin". 

 Attachment name 

 Name of the file sent by AS2. This is an extension to the base AS2 specification and might not be supported by all partners. By default no file name is sent. 

 Recipient address 

 The endpoint URL of the receiving gateway ,requires protocol prefix in URL (http:// or https://). 

 AS2 documentation 

 File containing instructions and certificates for the installation. You should download it and send it to your AS2 partner. 

 Compress message 

 Should the message be compressed or not? 

 Encrypt message 

 Should the message be encrypted or not? 

 Certificate for encryption 

 Certificate used for message encryption. Provided by your partner. 

 Encryption algorithm 

 Select algorithm used for encrypting message, if any. 

 Sign message 

 Should the message be signed or not? 

 Certificate for signature 

 Local certificate to use for signing AS2 messages. The certificates are kept in the environment certificates store. 

 Signing algorithm 

 Select algorithm used for signing the AS2 message. DEFAULT is SHA-1. 

 Request receipt 

 Should a receipt be sent when a request is received or not. 

 Asynchronous receipt 

 Should the receipt be sent asynchronously or not. 

  Signed receipt 

 Should the receipt be signed or not. 

 MIC algorithm 

 Select Message Integrity Code algorithm used to compute the MDN of the message. DEFAULT is SHA-1. 

 Message signature enforced 

 Should message signature be enforced or not. This parameter only applies if no AS2 IN gateway is configured for this partner (same AS2 FROM and AS2 TO). 

 Certificate for verification 

 Certificate used for message verification. Provided by your partner. This parameter only applies if no AS2 IN gateway is configured for this partner (same AS2 FROM and AS2 TO). 

 Maximum retries 

 Maximum number of retries if message sending failed. Default is 8 times. 

 Retry interval 

 Interval of time before trying to send message again (in seconds). Default is 1800 (30 minutes). 

 

To report AS2 parameters to the other party, dowload the AS2 documentation ZIP file. This file can be sent to the other party to give them all parameters they will require to establish a communication with your channel.

Note: 

  • The Listening ports for the AS2 Gateway are:

  1. When using the HTTPS protocol the Listening port is 443.

  2. When using the HTTP protocol the Listening port is 80.

  • If there is a file name provided in the "Message In" or "Message Out" which contain ~ tilde character, All browser based on Chromium will replace the ~ tilde character by the _ underscore character when you try to download the file from the Babelway interface, For more details you can check this link https://bugs.chromium.org/p/chromium/issues/detail?id=479419
  • The maximum file size accepted by this gateway is 100/250 MB.
  • The maximum filename supported for the AS2 "Gateway Out" is 56 characters.
