Scoped authentication
Account API tokens authorize only the supported client retrieval contract. Administrative APIs remain protected by account sessions and role checks.
Retrieval and realtime events
Clients can retrieve permitted SMS records and subscribe to signed message, number and earnings events. Webhook signatures allow receivers to verify the raw request body.
Operationally safe integration
Pagination, date filters, idempotency, rate controls and explicit error responses make integrations predictable under real traffic.
Frequently asked questions
Where is the API reference?
The public developer reference is available from the Documentation link and contains only the supported SMS retrieval contract.
Are test calls billable?
Configuration tests use synthetic data and do not create SMS, payout or delivery jobs.
