Applicability Statement 2 (AS2)

Field	Description
Recipient Endpoint	The endpoint URL of the recipient.
Authorization Type	The type of HTTP authorization scheme to use for the connection. You can choose one of the following options: none: No additional authorization scheme will be executed at run time. For example, when you specify a user name and password, but do not specify a value for the authorization type, the user credentials are not inserted into an authorization header. basic: When the application requires or supports HTTP basic authentication for user name and password.
From	The AS2 ID of the sender.
To	The AS2 ID of the recipient.
Response Timeout	The number of milliseconds Integration Cloud waits for a response before canceling its attempt to connect to the back end. In case the network is slow or the back end processing takes longer than usual, increase the Response Timeout value. It is recommended to specify a value other than 0. If you specify 0, Integration Cloud will wait indefinitely for a response.
Retry Count on Response Failure	The number of times Integration Cloud attempts to connect to the back end to read a response if the initial attempt fails. If an I/O error occurs, it will retry only if you have selected the Retry on Response Failure option.
Retry on Response Failure	Whether Integration Cloud should attempt to resend the request when the response has failed, even though the request was sent successfully. Select this option if you want to re-establish the connection.
Trust store Alias	Select the alias name of the Integration Cloud trust store configuration from the list. The trust store contains trusted certificates used to determine trust for the remote server peer certificates. Select Add New Truststore to add a new trust store from this list.
Keystore Alias	Select the alias for the Integration Cloud keystore configuration. This is a text identifier for the keystore alias. A keystore file contains the credentials (private key/signed certificate) that a client needs for authentication. Select Add New Keystore to add a new keystore from this list.
Client Key Alias	Alias to the private key in the keystore file specified in the Keystore Alias field. The outbound connections use this key to send client credentials to a remote server. To send the client’s identity to a remote server, you must specify values in both, Keystore Alias and Client Key Alias fields.
Hostname verifier	Select a hostname verifier implementation for guards against man-in-the-middle (MITM) attacks from the list. The default is org.apache.http.conn.ssl.DefaultHostnameVerifier. This enables hostname verification. Select org.apache.http.conn.ssl.NoopHostnameVerifier from the list to disable hostname verification.
Username	The name of the user account that the AS2 connection will use to connect to the AS2 provider.
Password	The password for the user name provided in the Username field.
Compression	Select this option to compress an outbound AS2 message.
Sign Message	Select this option to sign an outbound AS2 message.
Signing Algorithm	The signing algorithm to use for an outbound AS2 message. The available options are: MD5 SHA-1 SHA-256 SHA-384 SHA-512
Signing Keystore and Key Aliases	The keystore aliases and the key aliases in the keystore to use for signing an outbound AS2 message.
Receive Signed Message	Select this option to receive a signed inbound AS2 message. If you select this option and the incoming AS2 message is not signed, then an Insufficient message security error is encountered and shared with the sender if MDN is requested by the sender.
Signature Verification Certificate	The certificate to use for verifying an inbound signed AS2 message.
Encrypt Message	Select this option to encrypt an outbound AS2 message.
Encryption Algorithm	The encryption algorithm to use for an outbound AS2 message. The available options are: RC2 40 RC2 64 RC2 128 DES TripleDES AES 128 AES 192 AES 256
Encryption Certificate	The certificate to use for encrypting an outbound AS2 message.
Receive Encrypted Message	Select this option to receive an encrypted inbound AS2 message. If you select this option and the incoming AS2 message is not encrypted, then an Insufficient message security error is encountered and shared with the sender if MDN is requested by the sender.
Decryption Keystore and Key Aliases	The keystore aliases the key aliases in the keystore to use for decrypting an inbound AS2 message.
Request MDN	Whether you want the recipient to return an MDN to the sender. You can select one of the following options: None: The recipient of the AS2 message does not return an MDN to the sender. Synchronous: The recipient of the AS2 message returns an MDN to the sender through the same HTTP connection used to send the original AS2 message. Asynchronous: The recipient of the AS2 message returns an MDN to the sender through a different HTTP connection instead of the one used to send the original AS2 message.
Request Signed MDN	Select this option if you want the recipient to sign an AS2 MDN. Ensure that you also select an option in the Request MDN field if you want the recipient to sign and return an AS2 MDN.
Asynchronous MDN Endpoint	Type your endpoint URL that accepts an inbound AS2 MDN if you selected the Asynchronous option for Request MDN.
AS2 Version	Select the AS2 protocol version to use from the list.
Enable SNI	Server Name Indication (SNI) is an extension to the TLS protocol by which a client indicates which host name it is attempting to connect to at the start of the handshaking process. Enable this option if the SaaS provider offers SNI-based TLS connectivity, and if you want to connect to an SNI enabled SAAS provider to send the host name specified in the Server URL field, as part of the TLS SNI Extension server_name parameter.
SNI Server Name	If you want to explicitly specify a host name to be included as a part of the SNI extension server_name parameter, in case the host name is other than the host name specified in the Server URL field, specify the host name value in the SNI Server Name field.
