cart.applyDiscount

com.droplinked.mcp/server · Verify this server

Apply a discount or coupon code to a droplinked cart. Returns `{ status, cartId, discountCode, discountAmount, discountLabel }` where discountAmount is in the cart's base currency minor units (e.g. cents). Call this after cart.addLine and before start_checkout / process_payment. Surfaces structured error reasons (CART_NOT_FOUND / INVALID_DISCOUNT_CODE / DISCOUNT_EXPIRED / DISCOUNT_NOT_APPLICABLE / BACKEND_BAD_REQUEST / BACKEND_UNAVAILABLE) so the orchestrating agent can retry with a different code or proceed without a discount.
