• This API is the same format as the old TIPPERS API
  • Checkout the postman collection file in this repo (ZotBinsAPI.postman_collection.json) for request examples.
• ZotBinsAPI.py is the script that runs the flask app which acts as a middle man between user (us) and the database.
  • It requires two extra files that aren't included in this repo: config.py (contains db info) and queries.py (contains sql queries)
