Wix calls this method to retrieve a list of charges for a paid instance of your app. This happens when Wix creates an invoice or in case the customer wants to preview how much your app would charge them at the moment.

You must return the charges in the currency that's specified in the request, you aren't allowed to return more than 5 charges, and their sum must be lower than the charge limit.

You may not bill customers for any usage that didn’t occur during the period Wix specifies when retrieving the charges. If Wix discovers that your app has charged customers for usage outside of an invoice's specified period, we may take action such as blocking your app from charging the customer, removing your app from the Wix App Market, revoking your access to the Wix developer program, or pursuing legal action to recover damages caused by overcharging. We understand that mistakes can happen and encourage you to contact the Wix App Market team immediately if you become aware of any overcharging issues so that we can work together to resolve the situation.
