Point Shop Rework

[aletya]

• Context
  • Previously, we had a massive google docs of QR codes, each corresponding to one instance of a shop item. When it was scanned, the counter of the item in the shop went down
• Goals
  • Instead of doc with qr codes, attendees purchase redeemable tickets
  • Staff scans these redeemable tickets - they get marked as used
• Affected endpoints
  • POST /shop/generate-order (new)
    • Staff generates a non-expiring qr code for the specified items, that will be scanned by an attendee to checkout
  • POST /shop/fulfill-order (new)
    • Attendee scans ticket QR code → order gets marked as used (subtracts the cost from the authenticated user, as well as subtracts the item count from the shop)
• We may need a new DB to mark tickets as unused or used. As well as the items in the ticket (grainy qr code problem)
