Configure CPQ price rules (SBQQ__PriceRule__c) with conditions and actions

Steps

1. A price rule consists of a parent SBQQ__PriceRule__c record, one or more SBQQ__PriceCondition__c child records defining when the rule applies, and one or more SBQQ__PriceAction__c child records defining what field to update and with what value.
2. Create the price rule header: POST /services/data/{apiVersion}/sobjects/SBQQ__PriceRule__c with fields such as Name, SBQQ__Active__c (true), SBQQ__EvaluationOrder__c, and SBQQ__Scope__c (Quote or Quote Line, verify field values against current CPQ docs).
3. Create price conditions: POST /services/data/{apiVersion}/sobjects/SBQQ__PriceCondition__c, referencing the SBQQ__Rule__c lookup to the price rule, and specifying the tested object, field, operator, and value.
4. Create price actions: POST /services/data/{apiVersion}/sobjects/SBQQ__PriceAction__c, referencing the SBQQ__Rule__c lookup, and specifying the target field (SBQQ__TargetField__c) and the value source.
5. After creating or modifying price rules, trigger a CPQ quote recalculation via QuoteCalculator to verify the rule fires as expected.
6. Use the CPQ Price Waterfall view in the Salesforce UI to debug which rules applied during calculation.
