Understanding the usage fields

FieldWhat it means
minutes_included_limitThe total included minutes granted by the client’s current plan for this billing period. Resets at period end.
minutes_included_usedIncluded minutes consumed so far in the current period.
minutes_addon_balanceRemaining balance of add-on pack minutes. Does not reset at period end — carries forward until exhausted.
minutes_billable_usedMinutes consumed beyond both the included limit and the add-on balance. These will be billed as overage.

​
How minutes are consumed

Incoming call minute
  → first draws from minutes_included_limit
  → once exhausted, draws from minutes_addon_balance
  → once both exhausted, increments minutes_billable_used (overage)
Overage minutes result in a Cycle — Usage payment request at the end of the billing period if the plan has a per-minute overage rate configured.
