Steps to add an API call to an app-module

1. Find the endpoint of the API call, and search the common/exp-data/src/resources folder for existing Resource files that hit that endpoint.
• If there's an existing resource file with the endpoint, you will add the API call there.
• If not, you will need to create a new resource file.
• Model this resource file after existing resources. Define the API call according to the swagger specifications.
2. Define a data structure in the resource file for the input & output payload of the API if more than one data type is needed.
3. Add an epic reducer in the .ducks file that imports the resource and calls the API.
4. Combine the epic into the root epic in the .epics file.
5. The API call will now be made whenever the reducer is triggered.
