@amirhosseini This sounds like business logic, nothing to do with subscriptions. You’ll need to model credits and calls in your application, then check a user’s “balance” (credits − calls) to see whether they can place any more calls.

Spark Minute Base Billing Plans
Hi I was wondering if I can use spark billing plans based on minutes. we are providing a call track system and we need to now can we use spark plans based on our credit system. For example, each credit would use for one minute call. We need to now can we end up the plan when the user's credit ran out?
