I'm surprised to see there doesn't appear to be a way to issue refunds for in channel purchases. In the billing agreement and FAQ I don't see any mention of this, and I can't find anything in the developer portal. I can view sales transactions but there's no option to refund them.
I looked at the Web Services API that's described here: http://sdkdocs.roku.com/display/sdkdoc/Web+Service+API
And there appears to be an API endpoint to cancel a subscription, but nothing for refunding in-channel purchases.
Does this mean that customers must contact Roku to get a refund? Who should they contact exactly? Is there any info on this?
