The FlipSend API
Email, SMS and fax. One API. All Australian.

Channels
Three channels, one integration.
Bulk campaigns and transactional email, authenticated on your own sending domain.
SMS
Bulk and two-way SMS, with replies and opt-outs returned to your systems.
Fax
Fax for regulated document delivery, with per-recipient status on every page.
How it works
Built the way developers expect.
One endpoint sends to any channel. Authenticate, post a message, and read the result. The API does the work that regulated senders would otherwise build themselves, so opt-out handling, suppression and audit logging are not yours to maintain.
JSON over HTTPS
Token-based authentication with multi-factor support. No SDK required, though you can use one.
Your reference, echoed back
Every message carries a reference you set. It comes back in reports, so reconciling against your own records is exact.
Events surfaced back to you
Delivery, open and click events are returned as they happen, ready to feed your own reporting.
Versioned API surface
Integrations do not break underneath you. Changes ship behind a new version, on your schedule.
