Suggested Coding Interview Stories

Story	Points
In order for other developers to utilize the API, implement Swagger/OpenAPI	2
The CTO has requested we standardize our API documentation. Change the title of your swagger document to "Fool Commerce API."	1
Add a new endpoint that allows searching for a customer by email address.	1
BI has noticed some customers have purchased the product more than once. Setup the API to prevent customers from ordering a product they currently own.	1
Add a way for to return all the products for a given "brand".	1
Marketing has decided they want to track the type of payment used for each order. Record what type of payment method the customer used. (Credit Card, Apple Pay, Google Pay, etc.).	2
As it stands, orders in the system cannot be cancelled. Add a way to keep track of the status of an order. The statuses of "Active" and "Cancelled" come to mind as a good start.	2
