Billing and validation

resource_type must be concurrent_calls or cps.
quantity must be an integer from 1 through 10000.
Pricing uses the account’s assigned pricing tier and applicable pricing brackets.
The tier’s block-size, minimum-quantity, and maximum-quantity rules are enforced.
A successful purchase immediately debits the first month’s charge.
The subscription is created as active and scheduled to renew every 30 days.
The purchase fails if the account has no pricing tier, the quantity violates its pricing rules, or the balance debit fails.

Do not automatically retry a timed-out purchase. First retrieve the account and check its balance to avoid a duplicate charge.
