Billing

The Billing API enables partners to retrieve invoice information and manage their active subscriptions.

An Invoice object is automatically created when a new partner is added to the system. Each partner has one invoice, which is continuously updated as new charges occur.

In general, CarrierX invoice items can be of three types:

• DID rentals,
• event-based, e.g. calls, messaging, lookup, TTS requests to the API, etc.,
• subscription-based charges, i.e. any recurring regular monthly charges.

A Rate Subscription object is a customizable, recurring invoice item billed on a monthly basis. It allows Partners to view their subscriptions and their details. Each subscription includes a price, which is determined by the quantity of subscribed units multiplied by the rate per unit (price== rate * quantity).
