How billing works
Buy credits before sending real faxes. mintfax reserves credits when you submit a fax and deducts them when delivery succeeds. If delivery fails permanently, the reserved credits return to your available balance. You are not charged for carrier errors.
Your account has separate live and sandbox balances. Each balance is shared by all environments of that type. Your first successful live credit purchase activates live sending.
Optional automatic top-ups
You can enable automatic top-ups and choose a credit package. When your balance falls below the 20% threshold, mintfax purchases that package again. A balance.low webhook also tells your application that the balance is low.
Automatic top-ups are optional. Card payments support Visa, Mastercard, American Express, and Discover.
Included with every account
- Signed webhooks for delivery status, with logs and retries for webhook delivery failures.
- Idempotency keys to prevent duplicate submissions when you retry a request.
- Automatic fax retries and documented errors to help your application handle delivery failures.
- A free sandbox with repeatable success and failure scenarios.
- Security and data controls, including encryption, configurable content retention, and audit log export.
- A Business Associate Agreement (BAA) and Data Processing Agreement (DPA), available to sign in the dashboard at no extra cost.
