Response Structure

  • (dict) --
    • Connector (dict) --

      The structure that contains the details of the connector.

      • Arn (string) --

        The unique Amazon Resource Name (ARN) for the connector.

      • ConnectorId (string) --

        The unique identifier for the connector.

      • Url (string) --

        The URL of the partner's AS2 endpoint.

      • As2Config (dict) --

        A structure that contains the parameters for a connector object.

        • LocalProfileId (string) --

          A unique identifier for the AS2 local profile.

        • PartnerProfileId (string) --

          A unique identifier for the partner profile for the connector.

        • MessageSubject (string) --

          Used as the Subject HTTP header attribute in AS2 messages that are being sent with the connector.

        • Compression (string) --

          Specifies whether the AS2 file is compressed.

        • EncryptionAlgorithm (string) --

          The algorithm that is used to encrypt the file.


          You can only specify NONE if the URL for your connector uses HTTPS. This ensures that no traffic is sent in clear text.

        • SigningAlgorithm (string) --

          The algorithm that is used to sign the AS2 messages sent with the connector.

        • MdnSigningAlgorithm (string) --

          The signing algorithm for the MDN response.


          If set to DEFAULT (or not set at all), the value for SigningAlgorithm is used.

        • MdnResponse (string) --

          Used for outbound requests (from an Transfer Family server to a partner AS2 server) to determine whether the partner response for transfers is synchronous or asynchronous. Specify either of the following values:

          • SYNC : The system expects a synchronous MDN response, confirming that the file was transferred successfully (or not).
          • NONE : Specifies that no MDN response is required.
      • AccessRole (string) --

        With AS2, you can send files by calling StartFileTransfer and specifying the file paths in the request parameter, SendFilePaths . We use the file’s parent directory (for example, for --send-file-paths /bucket/dir/file.txt , parent directory is /bucket/dir/ ) to temporarily store a processed AS2 message file, store the MDN when we receive them from the partner, and write a final JSON file containing relevant metadata of the transmission. So, the AccessRole needs to provide read and write access to the parent directory of the file location used in the StartFileTransfer request. Additionally, you need to provide read and write access to the parent directory of the files that you intend to send with StartFileTransfer .

      • LoggingRole (string) --

        The Amazon Resource Name (ARN) of the Identity and Access Management (IAM) role that allows a connector to turn on CloudWatch logging for Amazon S3 events. When set, you can view connector activity in your CloudWatch logs.

      • Tags (list) --

        Key-value pairs that can be used to group and search for connectors.

        • (dict) --

          Creates a key-value pair for a specific resource. Tags are metadata that you can use to search for and group a resource for various purposes. You can apply tags to servers, users, and roles. A tag key can take more than one value. For example, to group servers for accounting purposes, you might create a tag called Group and assign the values Research and Accounting to that group.

          • Key (string) --

            The name assigned to the tag that you create.

          • Value (string) --

            Contains one or more values that you assigned to the key name you create.
