 # APIVendingMachine
 
-Design an API for a vending machine, allowing users with a “seller” role to add, update or remove products, while users with a “buyer” role can deposit coins into the machine and make purchases. Your vending machine should only accept 5, 10, 20, 50 and 100 cent coins

-**Tasks**
+**Key points**
 
 - REST API should be implemented consuming and producing “application/json”
 - Implement product model with amountAvailable, cost (should be in multiples of 5), productName and sellerId fields

 - Implement /buy endpoint (accepts productId, amount of products) so users with a “buyer” role can buy a product (shouldn't be able to buy multiple different products at the same time) with the money they’ve deposited. API should return total they’ve spent, the product they’ve purchased and their change if there’s any (in an array of 5, 10, 20, 50 and 100 cent coins)
 - Implement /reset endpoint so users with a “buyer” role can reset their deposit back to 0
 - Take time to think about possible edge cases and access issues that should be solved
-
-**Evaluation criteria:**
-
-- Language/Framework of choice best practices
-- Edge cases covered
-- Write tests for /deposit, /buy and one CRUD endpoint of your choice
-- Code readability and optimization
-
-**Bonus:**
-
 - If somebody is already logged in with the same credentials, the user should be given a message "There is already an active session using your account". In this case the user should be able to terminate all the active sessions on their account via an endpoint i.e. /logout/all
-- Attention to security
-
-## Deliverables
 
-A Github repository with public access. Please have the solution running and a Postman / Swagger collection ready on your computer so the domain expert can tell you which tests to run on the API.
