Developers
API integration
One HTTP POST sends a message. The response returns a message id, and per-message delivery status flows back as carriers confirm — the same lifecycle shown in the illustration above.
The current API reference ships inside your account after signup. Want it before committing? Talk to us and we will walk you through the live endpoints.
