JDE Orchestration calling internal REST Connection - how to access the result and pass to the next o

JDE 9.2.5.6 Orchestrator.

When getting data from the Connector - database, the format is incorrect to send to a 3rp party API so I embedded it in an orchestration so I could manipulate the output to be the correct format. However, when calling that Orchestration from a REST API (internal) to eliminate the dreaded [] surrounding the data, I can't access the output as a parameter to use for the next API call.

I can't use an array, I just need the entire string to pass through.

We seem to be doing a ton of manipulation to get a simple string formatted and sent on to the next API. Probably a ton of misunderstanding on my part!
