The SFTP Connector allows you to send and receive files from a web based SFTP server. To integrate with FTP or FTP over SSL (FTPS), you will need to use FTP instead.
Each of the tasks use an SFTP Connection, for more information on setting up and managing connections see the page Connecting to an SFTP Server. The connector supports both username/password and public key authentication.
