Sendix API
REST + JSON reference for the public Sendix developer surface: email, domains, inbound, webhooks, audiences, automations, templates, logs, and stats.
What is Sendix?
Sendix is a developer-first email platform. Transactional sends, marketing broadcasts, inbound parsing, automations, suppressions, and analytics all share the same public HTTP API surface. The dashboard also has private account, billing, and admin routes that are intentionally outside this developer reference.
Base URL

Four invariants you can lean on across every endpoint.
- Predictable RESTResource-oriented URLs, JSON bodies, standard verbs.
- Signed everythingHMAC on webhooks, bearer-scoped API keys.
- No SDK lock-inPlain HTTP works. The Node SDK is a thin convenience.
- Versioned surfaceMajor compatibility lives in the URL; additive fields can arrive within v1.
