This approach ensures that both pieces of valuable information are easily discoverable for anyone facing a similar issue in the future.

Is it possible to run this callin.io node within the same workflow? Perhaps at the conclusion of the existing nodes.

You should place it within a sub-workflow. While it can reside in the same workflow file, I'd advise against using it in the same execution. Doing so might lead to processing a significantly larger volume of data.

Thanks for the reply. I just observed something with the data.

Is there a method to subscribe to a workflow and retrieve its results?

Another question is, what happens if I incorporate a custom node at the conclusion of the workflow?
