Restaurant ordering

Menus, modifiers, pickup and delivery through Openfront Restaurant stores.

  1. discoverRestaurantMenus lists menus. Cart buttons appear only if the store exposes createActiveCart and addActiveCartItem.
  2. addToCart accepts modifierIds, specialInstructions and orderType (pickup or delivery, default pickup).
  3. setRestaurantFulfillment saves details. Pickup needs name, email and phone. Delivery also needs street, city, postal code and a two-letter country code.
  4. Before payment the app checks for an empty cart, missing contact, missing delivery address and an unmet delivery minimum (Restaurant cart is not ready for payment).
  5. Pay with initiatePaymentSession and completeCart.

Restaurant requests send the cart proof in X-Restaurant-Cart-Proof and the _restaurant_cart_id cookie.
