Preview vs Commit

preview vs commit the nue cpq quote api offers two modes for creating quotes preview (dry run) and commit (persist) both modes execute the full pricing engine product resolution, bundle expansion, discount propagation, and price tag evaluation but differ in whether the result is saved to the database this guide explains when to use each mode, shows how the request and response differ, and demonstrates the common preview then commit pattern overview comparison aspect preview commit endpoint post /cpq/quotes\ preview post /cpq/quotes pricing calculation full pricing engine full pricing engine database writes none quote + line items persisted response quote id null real uuid request body identical identical use case validation, what if, ui previews creating finalized quotes authentication all examples below use the following headers const myheaders = new headers(); myheaders append("nue api key", "your api key here"); myheaders append("content type", "application/json"); use case 1 preview mode pricing preview preview a quote to see calculated pricing without creating any database records this is ideal for pricing previews in a ui, what if analysis, ai driven validation, and integration testing request body { "opportunityid" "006xx000001abc123", "name" "q1 2026 enterprise license", "subscriptionstartdate" "2026 01 01", "subscriptionenddate" "2027 01 01", "subscriptiontermdimension" "month", "subscriptionterm" 12, "products" \[ { "productsku" "nue on salesforce", "uom" "user/month", "quantity" 10 } ] } curl curl x post 'https //api nue io/cpq/quotes\ preview' \\ h 'nue api key your api key here' \\ h 'content type application/json' \\ d '{ "opportunityid" "006xx000001abc123", "name" "q1 2026 enterprise license", "subscriptionstartdate" "2026 01 01", "subscriptionenddate" "2027 01 01", "subscriptiontermdimension" "month", "subscriptionterm" 12, "products" \[ { "productsku" "nue on salesforce", "uom" "user/month", "quantity" 10 } ] }' javascript fetch const myheaders = new headers();
