Calling REST APIs with Parameters

[salesopsintegra]

I need to be able to call a REST endpoint that takes a UserId as a parameter. I’m curious how I can leverage snaplogic to loop over an undetermined list of userIds from one REST endpoint to call another endpoint passing the user id.
Is this even possible in Snaplogic?

Sure. Use the JSON Splitter snap to split the output of the first REST Get into a set of documents, one per userId. Then configure the second REST Get with a query parameter whose value is an expression specifying the path of the userId in each input document.
