Authenticate and obtain a Salesforce access token.
Read the current quote model using QuoteReader (GET ServiceRouter?reader=SBQQ.QuoteAPI.QuoteReader&uid={quoteId}) to obtain the full model object.
Apply any field changes to the quote model object in memory (e.g., adjusting quantities, discount amounts, or line-level fields).
Send a PATCH request to /services/apexrest/SBQQ/ServiceRouter?loader=SBQQ.QuoteAPI.QuoteCalculator with the modified quote model JSON in the request body.
CPQ re-evaluates price rules, discount schedules, and block pricing and returns the recalculated quote model with updated net prices and totals.
Inspect the returned model for pricing changes before persisting with QuoteSaver.
Known gotchas
The QuoteCalculator uses the 'loader' query parameter despite being a calculation operation — do not use 'reader' or 'saver' for this call.
Sending a quote model with missing or corrupted fields can cause CPQ to produce incorrect prices silently; always start from a freshly read model.
Price rules with error actions may halt calculation and return an error in the response; check for error indicators in the returned JSON before proceeding.
