Write endpoints for frontend to interact with backend logic functions

[StevenMonty]

API route needed for each function with proper argument parsing/validation and responses in JSON format that the frontend can render.

Points: 4

Challenges:

• Once the backend was working from the admin console, exposing complex logic that had multiple steps in a single endpoint was difficult.
• Input data/parameter cleaning and verification.
• Deciding the best way to return unique identifiers to the front end in an intuitive way.
