Why do you need to transmit them "with line break" as opposed to just transmitting a list and letting the remote end deal with the list in whatever way it needs? The standard for transmitting lists via a simple single string would be JSON, and you can very easily transform a list of string items to JSON in Appian using a!toJson(). JSON is a standardized format so the remote end should be able to unpack the list with arbitrary difficulty and treat it however is needed.

I have the same question. Just use a delimiter.
