Promotion Evaluation and Execution API

Show customers adjusted prices by applying promotional discounts with a evaluation method that fits your business needs.

For evaluation, a parent group is created for each rule library. Promotions within this group are organized into three categories based on their application: line-level, cross-line, or cart-level. The Promotion Evaluation API takes the cart details and available coupons, and then sequentially applies all relevant discounts based on the configured evaluation method to determine the final adjusted price. When evaluating an item for promotions, the API scans 5 levels of the product’s category hierarchy before applying the right promotion based on the selected evaluation method.

The API response provides a complete breakdown of the discounted cart, including the final adjusted total price, the adjusted price for each line item, and a list of any non-pricing rewards available. If a cart contains a product that doesn't exist in the Salesforce catalog, the API ignores the unsynced products while evaluating line-level and cross line level promotions and applies the eligible promotions for the cart.
