Additional charges on top of Subscriptions

You can charge customers on top of their monthly subscriptions. Think of this as a sort of Usage-Based Subscription where your API can instruct how much to charge the customer based on your own estimate of your software's usage like:

Credits
Data
Storage
API Calls

This charge will be added to an existing Subscription and will generate a separate invoice.

API endpoint to charge any amount on top of existing Subscription

You can charge as many time you want:

"description": "Transaction description",
"items": [{
 "name": "overusage A",
 "value": 200,
},{
 "name": "overusage B",
 "value": 500,
}]

In above example, the customer will be charged with $2 for Overusage A and $5 for Overusage B.

There will be:
