When you create coupons, you may want to see a report of each coupon and what users have redeemed them. The sales report will show coupon redemptions related to invoices and list the revenue from each purchase.
To export data related to coupons, navigate to the Sales tab, then go to Invoices. On the Invoices page, go to Filters, click on Add new filter, and select Coupon. Under the Choose Content field, select which coupon you want to draw data from, and click on Add Filter. From there, click Export CSV to generate a report to be downloaded.
To download the file, navigate to Settings, then go to Exported Files, find the report you generated, and click Download.
