Design the endpoints

Each exercise describes a real system and a list of requests. For every request, pick the HTTP method, the path and, where asked, the status code the server should return. Check, read why, fix the red ones.

• Online shop: catalogue, cart and orders

  Products, a shopping cart and orders: eight requests to map onto methods, paths and status codes.

  8 requests

• Hotel booking: no double bookings

  Search, book, move and cancel hotel rooms, including what the server answers when two guests want the same room.

  7 requests

• Payments: retries, refunds and reports

  Charge cards safely under retries, refund part of a payment, build a slow report, and handle a token without the right scope.
