SFTP Send File to a remote server

Question

Hello, 
 I'm trying to send a file from my Appian application to a remote server that has its own hostname, username, password, and key file . I have implemented the process to do this. 
 While attempting to connect to this remote server, I have configured the file transfer configuration like this: 
 
 ' type !{plugins.ps.appiancorp.com/.../} FT_Config '(
 serverPort : 22 ,
 serverHostName : cons!ETT_HostName,
 privateKeyFile : cons!ETT_SERVER_PRIVATE_KEY_RSA
)

However, I still don't know how to successfully connect to the server, even though the process does not throw any errors. How can I resolve this? I'm really stuck; I can't find documentation, tutorials, or even an explanation of how the plugin works for beginners, which is a very terrible thing for such an important plugin. 
 The problem is that the process is not throwing any errors and there's no logic to connect to the server without the username and password.

If your sFTP server just has username/password configuration, you would merely pass in the SCS external system key from the one you've hopefully already added into your Third Party Credential store in the Admin console. 
 The FT_Config object you eventually want to be passing over via the Smart Service can be as simple as this example, which is my current working one except for some object names sanitized: 'type!{http://plugins.ps.appiancorp.com/suite/types/}FT_Config'(
 serverHostName: cons!PROJ_sFTP_HOST_NAME,
 /*e.g. serverHostName: "test.rebex.net",*/
 serverPort: 22,
 timeout: 20000,
 scsExternalSystemKey: cons!PROJ_sFTP_EXTERNAL_SYSTEM_KEY,
 usePerUserCredentials: false()
) 
 (for yours, I assume you would continue also including the reference to your Private Key File just as you have it. But you'd definitely need to add the External System Key.)

Are there any Error or Status values being returned from your sFTP node? 
 
 Can you share your "remote file path" and "document to send" configurations? Note that the "remote file path" should include the sFTP server's path from root as well as the full eventual remote filename, as specified in the sFTP plug-in documentation.

This is an sFTP server, your remote path wouldn't have "c:" in it. The root directory should simply be "/". Directories are denoted with a forward slash, not backslashes like in Windows. 
 1) Are you able to view the sFTP's root directory through a normal sFTP client to verify that the path you're trying to send the file to actually exists? 
 2) I'd suggest you try to send it to the root directory first, just to see if you can get it to work.

You need to configure the credentials in Third Party data store in Admin Console and call it in your code using the key you will give while configuring the third party data store

Caro said: I assume that if I have a private key file, the password is not necessary, but I'm not sure 
 This is something you need to discuss with your sFTP administrator. Did they tell you to provide a private key file? If your sFTP login is really a username only and no password (and you can login that way with a regular FTP client like fileZilla), then you probably don't need the key file.
