Transfer / Client / create_connector

create_connector#

Transfer.Client.create_connector(**kwargs)#

Creates the connector, which captures the parameters for a connection for the AS2 or SFTP protocol. For AS2, the connector is required for sending files to an externally hosted AS2 server. For SFTP, the connector is required when sending files to an SFTP server or receiving files from an SFTP server. For more details about connectors, see Configure AS2 connectors and Create SFTP connectors.

Note

You must specify exactly one configuration object: either for AS2 ( As2Config) or SFTP ( SftpConfig).

Parameters:

  • Url (string) –

    [REQUIRED]

    The URL of the partner’s AS2 or SFTP endpoint.

  • As2Config (dict) –

    A structure that contains the parameters for an AS2 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.

      Note the following:

      • Do not use the DES_EDE3_CBC algorithm unless you must support a legacy client that requires it, as it is a weak encryption algorithm.

      • You can only specify NONE if the URL for your connector uses HTTPS. Using HTTPS 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.

      Note

      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.

    • BasicAuthSecretId (string) –

      Provides Basic authentication support to the AS2 Connectors API. To use Basic authentication, you must provide the name or Amazon Resource Name (ARN) of a secret in Secrets Manager.

      The default value for this parameter is null, which indicates that Basic authentication is not enabled for the connector.

      If the connector should use Basic authentication, the secret needs to be in the following format:

      { "Username": "user-name", "Password": "user-password" }

      Replace user-name and user-password with the credentials for the actual user that is being authenticated.

      Note the following:

      • You are storing these credentials in Secrets Manager, not passing them directly into this API.

      • If you are using the API, SDKs, or CloudFormation to configure your connector, then you must create the secret before you can enable Basic authentication. However, if you are using the Amazon Web Services management console, you can have the system create the secret for you.

      If you have previously enabled Basic authentication for a connector, you can disable it by using the UpdateConnector API call. For example, if you are using the CLI, you can run the following command to remove Basic authentication:

      update-connector --connector-id my-connector-id --as2-config 'BasicAuthSecretId=""'

    • PreserveContentType (string) –

      Allows you to use the Amazon S3 Content-Type that is associated with objects in S3 instead of having the content type mapped based on the file extension. This parameter is enabled by default when you create an AS2 connector from the console, but disabled by default when you create an AS2 connector by calling the API directly.

  • AccessRole (string) –

    [REQUIRED]

    Connectors are used to send files using either the AS2 or SFTP protocol. For the access role, provide the Amazon Resource Name (ARN) of the Identity and Access Management role to use.

    For AS2 connectors

    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.

    If you are using Basic authentication for your AS2 connector, the access role requires the secretsmanager:GetSecretValue permission for the secret. If the secret is encrypted using a customer-managed key instead of the Amazon Web Services managed key in Secrets Manager, then the role also needs the kms:Decrypt permission for that key.

    For SFTP connectors

    Make sure that the access role provides read and write access to the parent directory of the file location that’s used in the StartFileTransfer request. Additionally, make sure that the role provides secretsmanager:GetSecretValue permission to Secrets Manager.

  • 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. Tags are metadata attached to connectors for any purpose.

    • (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) – [REQUIRED]

        The name assigned to the tag that you create.

      • Value (string) – [REQUIRED]

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

  • SftpConfig (dict) –

    A structure that contains the parameters for an SFTP connector object.

    • UserSecretId (string) –

      The identifier for the secret (in Amazon Web Services Secrets Manager) that contains the SFTP user’s private key, password, or both. The identifier must be the Amazon Resource Name (ARN) of the secret.

    • TrustedHostKeys (list) –

      The public portion of the host key, or keys, that are used to identify the external server to which you are connecting. You can use the ssh-keyscan command against the SFTP server to retrieve the necessary key.

      The three standard SSH public key format elements are <key type>, <body base64>, and an optional <comment>, with spaces between each element. Specify only the <key type> and <body base64>: do not enter the <comment> portion of the key.

      For the trusted host key, Transfer Family accepts RSA and ECDSA keys.

      • For RSA keys, the <key type> string is ssh-rsa.

      • For ECDSA keys, the <key type> string is either ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, or ecdsa-sha2-nistp521, depending on the size of the key you generated.

      Run this command to retrieve the SFTP server host key, where your SFTP server name is ftp.host.com.

      ssh-keyscan ftp.host.com

      This prints the public host key to standard output.

      ftp.host.com ssh-rsa AAAAB3Nza...<long-string-for-public-key

      Copy and paste this string into the TrustedHostKeys field for the create-connector command or into the Trusted host keys field in the console.

      • (string) –

  • SecurityPolicyName (string) – Specifies the name of the security policy for the connector.
