Let me know if that doesn't cover your use case.
BTW, if you're hitting a REST API, you might want to try using the Python tool (it's an embedded Jupyter interface that will default to just running the pure python code when the workflow is executed without a user configuring it), just because I prefer using requests library over using the Alteryx download/curl tool myself.
