This pricing model is Alpha and still in development. If you want to implement this pricing model then please submit a request.
Usage-based pricing lets you charge users on a recurring, monthly basis for their usage in your app – e.g., a user sends 100 SMS marketing messages in a month.
You can choose to charge a flat monthly base fee as well as a per item charge with this model.
At the end of the billing cycle, Wix makes an Service Plugin call to request the usage-based charges, and charges the user accordingly.
You define a usage cap with the Get Charge Limit endpoint that Wix calls when a user chooses to upgrade the app plan. This can be increased later on by the user, once they’ve purchased a plan.
Wix doesn't notify users when a usage cap hits the limit – it's your app's responsibility to let them know.

If you add a price please add it in the {}, e.g., if you charge based on the usage of SMS, please > add it like this: “{0.5} per SMS”, in the app listing it will look like this: “0.5$ per SMS”. This > ensures that the amount is automatically converted to other currencies.
*The default currency is in US$
