We would like to implement a “pay-as-you-go” subscription plan:
- the merchant installs the app and subscribes the plan (let’s say 0,10€ per stored document) preauthorizing a transaction
- he starts using the service through the app
- as soon as he reaches 100€ limit the card will be charged and an invoice will be send her/him by our system
- as long as he continues using the app this cycle goes on
I cannot understand if and how this is feasible given the current Poynt APIs
