Learn how to use ZQFClient helper methods to update quote fields, products, or charges by creating and dispatching mutation events.

1. Create a ZQFClient instance from quoteState.
2. Choose the helper method based on the type of update you want to perform:

   • Use updateQuote(...) or updateQuoteField(...) to update quote fields.

   • Use addProducts(...) or addProductsInInterval(...) to add new sellable products or rate plans.

   • Use charge helpers only when the target rate plan already exists in the quote.

   • Use bulk or grouped update helpers when you need to update several records together.

3. Call the selected helper method to create the event.
4. Dispatch the returned event by using this.dispatchEvent(...).

   Example: update quote fields

   this.dispatchEvent(
     zqf.updateQuote({
       Name: 'Updated Quote Name',
       zqu__Billing_Region__c: 'EMEA'
     })
   );
   

   Example: update charges in a selected interval

   const updateProductsEvent = qs.updateChargesInInterval(2, [
     {
       filter: (charge) => charge.record.Name === 'Per MB Charge',
       update: { zqu__Discount__c: 20 }
     }
   ]);
   
   this.dispatchEvent(updateProductsEvent);
