Is it possible to access an external service via TCP or named pipes rather than

Hi James. I know RDMS's can be configured for named pipes and you should be able to modify your database connection string in your appian-ds.xml file to use named pipes. I found www.connectionstrings.com/ to be helpful. This will affect how your query rules and data store nodes communicate with the RDBMS.

As far as other integrations go, the web services node was designed specifically for HTTP/S. There's no reason you couldn't create a custom plug-in that uses names pipes for other types of named pipes integrations, though.

Thanks Richard. This is looking like custom code route to me. Not liking what I have found on the web so far however.
