| Hosts / Host Technical Reference | |
The generic FTP and FTP/s hosts enable a user to fully specify a client file transfer interface to an FTP server. If at all possible, use a pre-configured host specific to the target server; this will save the effort of having to research, specify, and then debug the interface.
The generic FTP host provides an interface over non-secure FTP. If you or your trading partner requires Secure Socket Layer (SSL) FTP, use the generic FTP/s host.
Not all FTP servers will support or require the full set of host commands allowed by VersaLex. At a minimum, the server must support PUT and/or GET. The following action commands are available on VersaLex:
| Command | Purpose | Underlying FTP method | |
|---|---|---|---|
