Create or update the shop program: shop name, reward text, stamps required before a reward. Returns the program and its join URL (the poster target).
Add one stamp to a customer card. Identify the card by its 8-character code (from the customer page) or by its token. One stamp per card per day unless allow_multiple is true.
Read one customer card: how many stamps, what the reward is, whether it is ready to redeem.
Redeem the reward on a card that has reached its required stamps. Resets the stamp count and increments the rewards-earned counter.
Program plus this month stamp usage and quota, so a shop can tell how close it is to the free limit.
