Combine 3 APIs together in Rails

There were 3 stages to this and my group completed 2 of 3. This is the last stage for my group project.

We each have our own API. Edamams Nutrition facts API, Yelp Search API and an SMS sender API. Each has their own rails environment and functional databases. My professor said, “okay now combine them into one rails application, combine their databases, and create a webpage that makes use of these APIs. Make it in a way so they interact with each other” and that’s where we need help.
