Hi, I need to make the subscription preview via REST API including consumption for rateplancharge of type usage. In the knowledge center https://knowledgecenter.zuora.com/BC_Subscription_Management/Subscriptions/C_Previewing_a_Subscription#Preview_Active_or_Canceled_Subscriptions it is written that I can preview the subscription in Active status, and in the https://www.zuora.com/developer/api -reference / # operation / POST_PreviewSubscription it is written that a parameter exists (includeExistingDraftDocItems or includeExistingDraftInvoiceItems depending on the version) to exclude from the preview the usage included in draft invoices. I can't find the construct to insert consumption of type usage, how should I do? Best regards Giancarlo. My API is the following: VERSION 196.0 / V1 / subscriptions / preview { "AccountKey": "A02909725" "contractEffectiveDate": "2019-04-04", "includeExistingDraftInvoiceItems": false, "invoiceTargetDate": "2019-04-04", "PreviewType": "InvoiceItem" "subscribeToRatePlans": [ { "chargeOverrides": [ { "productRatePlanChargeId": "{{productRatePlanChargeId for usage}}" } ] "productRatePlanId": "{{productRatePlanId}}" } ] "termType": "EVERGREEN" } RESPONSE { "success": true, "contractedMrr": 0, "totalContractedValue": null }
