This topic guides you through adding a product to a subscription by configuring dynamic pricing and setting pricing attributes.

1. Determine the values of the following variables and configure the dynamic pricing enabled charge in the product catalog accordingly:

   Variable	Description
   $AccountNum	The number of the account that will own the order. For example, A00000001 .
   $ProductRPId	The ID of the product rate plan to add to the subscription. For example, edcad42fa5697665a4d767394f590000. .
   $ProductRPChargeId	The ID of the product rate plan charge to use when adding the product rate plan. For example, 41137e9965e2445fbb57dae2daab7580. .
   $subscriptionNumber	The number of the subscription that will own the rate plans. For example, A-S0000001.
   $Today	Today's date. For example,2025-06-20.

2. Refer to the example payload to create a new order. In this example, you can set the value of pricing attributes: Site_Size and EffectiveDate directly in pricingAttributes. For the pricing attribute Subscription_RatePlan_Class that is mapped to the custom field RateClass__c, its value is set in customFields and automatically used by Zuora during list price lookup.
   Note:

   Assuming the subscription's renewal term length = 12 months.

   Request

   POST /v1/orders/

   Request Body

   { "orderDate": "$Today", "existingAccountNumber": "$AccountNum", "subscriptions": [ { "subscriptionNumber": "$subscriptionNumber", "orderActions": [ { "addProduct": { "productRatePlanId": "$productRatePlanId", "customFields": { "Channel__c": "Reseller", "RateClass__c": "Low" }, "chargeOverrides": [ { "productRatePlanChargeId": "$productRatePlanChargeId", "pricingAttributes": { "EffectiveDate": "2025-06-20", "Site_Size": 7 } } ] }, "triggerDates": [ { "name": "ContractEffective", "triggerDate": "$Today" }, { "name": "CustomerAcceptance", "triggerDate": "$Today" }, { "name": "ServiceActivation", "triggerDate": "$Today" } ], "type": "AddProduct" }

3. After the rate plan is subscribed successfully, you can retrieve the price and pricingAttributes value of the charge via the GET subscription end point. This is an example response of pricingAttributes of the charge created from "$productRatePlanChargeId" in the previous step.

   "price": 9.000000000,

   "pricingAttributes": {

   "Site_Size": 7,

   "Account_Type": "VIP",

   "EffectiveDate": "2025-06-20T00:00:00+08:00",

   "Subscription_Renewal_Term": 12,

   "Subscription_RatePlan_Class": "Low"

   }

   Note:

   pricingAttributes includes all the pricing attribute values including both external attributes and attributes mapped to Zuora object fields.
