Lucky Cart Core API is one of 6 APIs that [Lucky Cart](https://apis.io/providers/lucky-cart/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Transactions, Promotions, and Gamification. The published artifact set on APIs.io includes authentication docs.

The core Lucky Cart API. POST /cart/ticket submits a validated shopping cart — cart identifier, shopper identifier, gross and net amounts, and product lines — and Lucky Cart determines whether a game can be generated, returning a ticket plus the device-specific intro image and game URL. This is the only signed endpoint: the request body carries auth_ts, auth_key, auth_v "2.0" and auth_sign, an HMAC-SHA256 digest of the timestamp keyed by the site secret. Game data is read back at /{siteKey}/game/{cartId} or /{siteKey}/game/cust/{shopperId}, optionally suffixed with the device. Cart ingestion is asynchronous, so the read returns the literal error "Cart not found" until it completes and clients poll on a bounded attempt budget.
