Connection

The Connection stores the remote server address, timeout, and credentials used for SFTP access.

Property Type Description
Host String Host name or IP address of the remote server.
Port Integer Port to connect to. The default is 22.
Timeout (seconds) Integer Time to wait for the server before timing out.
Username String Username used to authenticate with the server.
Password Masked Account password, or the passphrase for an encrypted value in Client Private Key File Contents.
Client Private Key File Contents Masked SSH private-key file contents used for public-key authentication.
Certificate Certificate X.509 certificate containing an RSA or ECDSA private key used for SSH public-key authentication.

Setup Notes

Make sure the remote SFTP account can access the folders and files that the Workflow needs to use.

Choose one authentication configuration:

  • Enter Password for password authentication.
  • Enter the private-key text in Client Private Key File Contents. For an encrypted key, enter its passphrase in Password.
  • Select a Certificate containing an RSA or ECDSA private key. You can also enter Password when the server requires password authentication in addition to the certificate key.

Do not configure both Client Private Key File Contents and Certificate on the same Connection.

Remote paths are normalized to use forward slashes, so provide the server path exactly as the remote system expects it.

Methods

The SFTP Node exposes file operations and filtered directory listings against one remote SFTP server.

Read

Reads a file from the remote server and returns its content as a stream.

Parameter Type Description
Connection Connection SFTP Connection profile.
Path String Path of the remote file to read.
Return Type Description
Content Stream Stream containing the remote file content.

Write

Writes content to a file on the remote server and can replace an existing file when requested.

Parameter Type Description
Connection Connection SFTP Connection profile.
Path String Path of the remote file to write.
Content Stream Content stream to upload.
Overwrite Existing Boolean When true, an existing remote file is replaced.
Return Type Description
None None This method does not emit output values.

Copy

Copies a file to another location on the same remote server and can replace an existing destination file.

Parameter Type Description
Connection Connection SFTP Connection profile.
Path String Path of the remote file to copy.
Destination String Destination folder on the remote server.
Overwrite Existing Boolean When true, an existing destination file is replaced.
Return Type Description
None None This method does not emit output values.

Move

Moves a file to another location on the same remote server and can replace an existing destination file.

Parameter Type Description
Connection Connection SFTP Connection profile.
Path String Path of the remote file to move.
Destination String Destination folder on the remote server.
Overwrite Existing Boolean When true, an existing destination file is replaced.
Return Type Description
None None This method does not emit output values.

Delete

Deletes a file from the remote server.

Parameter Type Description
Connection Connection SFTP Connection profile.
Path String Path of the remote file to delete.
Return Type Description
None None This method does not emit output values.

Info

Retrieves metadata for a file stored on the remote server.

Parameter Type Description
Connection Connection SFTP Connection profile.
Path String Path of the remote file to inspect.
Return Type Description
Metadata Object Metadata for the selected remote file or folder.

List

Lists files in a remote directory using a wildcard filter and bounded subdirectory traversal.

Parameter Type Description
Connection Connection SFTP Connection profile.
DirectoryPath String Path of the remote directory containing the files to list.
Filter String Wildcard expression matched against file names. The default is *.
FolderDepthLimit Integer Maximum number of subdirectory levels to traverse, from 0 to 50. Set 0 to list only the supplied directory.
ReturnFullPath Boolean When true, each item contains the full path. When false, each item contains only the file name. The default is true.
Return Type Description
Files Array Matching files sorted by path. Each item includes FilePath, the one-based CurrentRow, and TotalRows.

The Node captures the complete listing before returning the output stream, so path, permission, and provider failures surface before downstream enumeration begins. No matches return zero rows. Only files are returned; duplicate full paths are removed before row numbers are assigned. Later file changes are not reflected in the snapshot.

Usage Notes

Use remote paths that are valid on the SFTP server. The Write, Copy, and Move methods create missing remote destination folders.

Copy and Move operate within the same remote server exposed by the Connection, so use separate steps if you need to transfer files between different servers.

The List method captures a snapshot before it returns the matching files. Use Filter and FolderDepthLimit to limit the listing.
