Path parameters

Field	Type	Required	Description
Promotion id	String	Yes	Indicates the unique identifier of the promotion. This is returned in the `data.id` field of the promotion payload during promotion creation.

Body parameters

This table describes the top-level fields required to create any type of cart promotion.

Field	Type	Required	Description
name	String	Yes	Indicates a unique name of the cart promotion. Character limit: 1-50.
type	Enum	Yes	Specifies the type of cart promotion. Supported values are: • POS (Point of Sale): Applies automatically at checkout when cart or purchase conditions are met. Constrain: If a POS cart promotion is not restricted to loyal customers(isLoyaltyOnly is false), it cannot have Customer level restrictions. • CODE: Requires the customer to enter a cart promotion code for redemption. Constrain: Code cart promotions cannot have Customer level restrictions. They also require Code level restrictions to be present. • CUSTOMER: Targets specific customer segments or individuals based on attributes or behaviour. • EARNING: Grants rewards (such as points or benefits) when earning conditions are fulfilled. • REWARD: Offers a direct reward, such as a discount or complimentary item, upon meeting specific conditions.
messageLabel	String	Optional	Specifies a label for the cart promotion message. There is no character limit set for labels. Example: SummerSale2025.
active	Boolean	Yes	Indicates if the cart promotion is active. Supported values: true, false. Default value is true.
priority	Integer	Yes	Specifies the order in which cart promotions are applied. Lower numbers have higher priority, with 0 being the highest. Example: If there are three promotions—A (priority 0), B (priority 1), and C (priority 2), the order of application will be A, then B, then C. Note: If customerActivationRequired is enabled, the priority order does not apply until the customer activates the promotion.
isStackable	Boolean	Yes	Indicates whether this cart promotion can be used with other cart promotions. Supported values: true, false. Default: false.
startDate	Long	Yes	Specifies the date and time when the cart promotion becomes active, as a Unix epoch timestamp in milliseconds (UTC). Example: 1757388651000 corresponds to 2025-09-12 06:30:51 UTC.
endDate	Long	Yes	Specifies the end date and time when the cart promotion expires, as a Unix epoch timestamp in milliseconds (UTC). Example: 1726123456789 corresponds to 2024-09-12 10:24:16 UTC.
campaignId	String	Yes	Specifies the unique identifier of the campaign that the cart promotion is linked to. Example: 12345. There is no validation for the campaign ID.
condition	Object	Yes	Specifies the rules that determine how the cart promotion applies.
..type	Enum	Yes	CART : Conditions based on the entire shopping cart's properties, like its total value or item count. Example: “Get $10 off when your subtotal is over $100.” TENDER : Conditions based on the customer's specific method of payment. Constrain: A TENDER condition must be paired with a TENDER action, and vice-versa. You cannot have a tender-based condition with a cart-based action. Example: “Receive 5% cashback when you pay with a Visa card.” COMBO_PRODUCT : Conditions based on the presence of multiple, specific products or product groups being purchased together. Example: “Buy a laptop and a mouse to get $50 off your total purchase.” PRODUCT : Conditions based on a specific group of products, evaluated by their quantity or total value. Example: “Buy at least two items from the 'Beverages' category to get 10% off.” See the "Condition Objects" tables below for the full structure.
action	Object	Yes	Specifies what happens when the cart promotion is applied.
..type	Enum	Yes	Specifies the scope of the action when the cart promotion is applied. Supported values: • CART_BASED : Applies to the entire cart. • PRODUCT_BASED : Applies to specific items in the cart. • TENDER : Applies a discount based on payment method. Constrain: A TENDER condition must be paired with a TENDER action, and vice-versa. You cannot have a tender-based condition with a cart-based action. • PER_UNIT : Applies a discount for every X units.FREE_PRODUCT : Makes a specific item in the cart free of charge. • FIXED_PRICE : Changes the price of a specific item to a set amount. Constrain: If you use a FIXED_PRICE action, the associated condition must be a PRODUCT or COMBO_PRODUCT type. A CART or TENDER condition is not supported for this action. • FREE_PRODUCT: Makes a specific item in the cart free of charge. Constraint: The freeProductAction object requires a nested productBasedCondition to define which specific product (or group of products) is made free. This action is inherently product-focused and is used to target specific items. See the "Action Objects" tables below for the full structure.
customerActivationRequired	Boolean	Optional	Indicates if a customer must opt-in for a cart promotion before it can be redeemed. If true, the cart promotion is issued as `INACTIVE` and requires a customer action to become `ACTIVE`.
maxIssuancePerCustomer	Integer	Optional	Defines the total number of times this cart promotion can be issued to a single customer.
promotionRestrictions	Object	Optional	Defines usage limits on the cart promotion, grouped by level : `Customer`, `Cart`, `Promotion`, `Code`. See the "Promotion Restrictions Object" table below for the full structure.
customFieldValues	Object	Optional	Defines a key-value map for storing custom metadata. The structure is user-defined (e.g., {"key": "value"}).
earningCriteria	Object	Conditional	Defines the conditions for earning a reward. Required when type is EARNING. See the "Earning Criteria Object" table below for the full structure.
maxEarningPerCustomer	Integer	Optional	Specifies the maximum number of times a customer can earn the reward from an EARNING type cart promotion.

Action Objects (specifies what happens when the cart promotion is applied)

The action object defines what happens when a cart promotion’s condition is met. In simple terms:

Condition = When does the offer apply?
Action = What benefit does the customer get?

Concept	Purpose	Example
condition	Specifies the trigger criteria for the cart promotion.	When the cart subtotal is ₹1,000 or more.
action	Specifies the reward action or benefit once the condition is satisfied.	Apply a ₹200 discount.

Action Types and Scenarios

1. CART_BASED

Applies a discount to the entire shopping cart when a cart-level condition is met. Example: Give a $200 discount when the cart subtotal is $1,000 or more.

The condition checks the cart’s total value; the action applies the discount to the entire cart.

2. TENDER

Applies a discount based on the customer’s payment method. Example: Give a $100 discount when the customer pays using a VISA credit card.

The condition checks the payment type; the action applies a discount tied to that payment.

3. PRODUCT_BASED

A product-based action is used when the cart promotion applies a discount or reward action to specific products in the cart—not to the entire cart or a payment method. This action type is most commonly used for item-level offers, where the benefit depends on the products purchased or their attributes (such as category, brand, or quantity).

When to use it

Apply a percentage or fixed amount discount on certain products.
Offer discounts only on products that meet specific criteria, such as category, brand, or SKU.
Reward a related product set, for example, “Buy product A, get a discount on product B.”
Run category-level or brand-level cart promotions.

4. FREE_PRODUCT

Makes one or more specific items in the cart free of charge. This is the ideal action for "Buy X, Get Y Free" cart promotions.

Example: Buy a laptop and get a computer mouse for free.

The system identifies the product to be discounted and reduces its price to zero.

5. FIXED_PRICE

Changes the price of specific items to a set amount, regardless of their original price.

Example: Get any large pizza for $10.

The system finds the qualifying item and overrides its original price with the new fixed price.

6. PER_UNIT

Applies a reward action repeatedly for each qualifying group of items or value. Example: Buy 2 Paint Buckets, get 1 Paint Brush free for every 2 buckets.

The condition checks the total quantity or amount, and the action applies a recurring reward action for each multiple of a defined value.

Comparison Table

Action Type	When to Use It	What It Does	Example cart Promotion
CART_BASED	When the discount applies to the entire cart total.	Gives a single discount based on the total value of all items in the cart.	Get $200 off when your cart total is $1,000 or more.
TENDER	When the reward action depends on the payment method used.	Applies a discount if the customer uses a specific payment mode.	Pay with a VISA card and get $100 off your total bill.
PRODUCT_BASED	When you want to discount specific products or categories.	Applies a fixed or percentage discount to particular items that meet set criteria.	Get 10% off all Paint Supplies.
FREE_PRODUCT	For "Buy X, Get Y Free" offers.	Reduces the price of one or more specific items to zero.	Buy a laptop and get a computer mouse for free.
FIXED_PRICE	To sell an item or group of items at a specific special price.	Overrides the original price of an item with a new, set price.	Get any large pizza for $10.
PER_UNIT	When the reward action should repeat per quantity or group.	Applies benefits repeatedly for each qualifying group of items or value.	Buy 2 Paint Buckets, get 1 Paint Brush free for every 2 buckets.

When the cart promotions action type is CART_BASED

Field	Type	Required	Description
.cartBasedAction	Object	Yes	Defines a reward action or discount that applies to the entire shopping cart once the cart promotion’s condition is met. It’s used when the benefit is calculated at the cart level, not per product or payment type. Example:Apply a $200 discount when the cart subtotal is $1,000 or more.
..type	Enum	Yes	Type of action. Supported value: `ABSOLUTE` (fixed monetary discount).
..value	Number	Yes	Fixed monetary amount for the discount.

When the cart promotions action type is PER_UNIT

Field	Type	Required	Description
.perUnitAction	Object	Yes	Defines a reward action that can be applied repeatedly.
..perUnitKPI	Enum	Yes	Metric used to group items. Supported: `QUANTITY`.
..perUnitDivider	String	Yes	Specifies a numerical value that specifies the minimum quantity of items that must be purchased before a specified action (such as a discount or free item)is repeated. Example : Customer buys any two items from the 'Shirts' category, they are eligible to receive one item from the 'Ties' category for free Here the perUnitDivider will be 2, since every two item purchased is eligible for a free item repeatedly.
..rewardAction	Object	Yes	Defines the specific benefit for each group.
...type	Enum	Yes	Type of per-unit reward action. Supported values : `PRODUCT_BASED`: This action applies a direct discount (either a fixed amount or a percentage) to specific items., Example :A "25% Off All Snacks" cart promotion . When a customer adds any item from the "Snacks" category to their cart, the system applies a 25% discount to the price of just those snack items. `FREE_PRODUCT`:This action makes a specific item free, often as part of a "Buy X, Get Y" offer. Example : A "Buy 2 Shirts, Get 1 Free" cart promotion . When the system detects three items from the "Shirts" category in the cart, it identifies the cheapest one among them and reduces its price to zero, making it free. `FIXED_PRICE`:This action changes the price of a specific item to a set amount, regardless of its original price. Example: An "Any Large Pizza for $10" deal. When a customer adds any pizza from the "Large Pizzas" category to their cart, the system ignores its original price (e.g., $18) and changes it to the special fixed price of $10.
...productBasedAction	Object	Conditional	Required when `rewardAction.type` is `PRODUCT_BASED`.
....type	Enum	Yes	Calculation method. Supported: `ABSOLUTE`, `PERCENTAGE`.
....value	Number	Yes	The amount or percentage of the discount.
