redux-api provides an easy and flexible way to interface with REST APIs in Redux (e.g. when building a React app). It works pretty well when there you know beforehand what API calls you're going to make, and define them in its configuration object.
But when you want to make multiple calls to the same endpoint, and don't know beforehand how many, you're a bit out of luck. In my case, I had a product listing where each product had a category and a score. In a summary overview, I wanted to show a histogram of the scores for each category. That means: first a request to the categories endpoint, and then for each of the categories, a request to the histogram endpoint.
This is an example of how to do that.
