  title: Novu Environments Events API
  description: 'The Novu REST API drives open-source notification infrastructure that sends multi-channel messages - email, SMS, push, chat, and an in-app Inbox - from a single workflow trigger. A trigger event fans a notification out across the channels defined in a workflow. This document models the core resources - Events (Trigger), Subscribers, Topics, the in-app Inbox feed, Messages, Notifications (activity), Workflows, Integrations, Layouts, subscriber Preferences, Environments, and Translations. Novu is open source (MIT) and self-hostable, and also runs as Novu Cloud with US and EU regions. All requests authenticate with a secret API key sent as `Authorization: ApiKey <NOVU_SECRET_KEY>`. Endpoints are grounded in Novu''s published API reference; request/response bodies are modeled at a representative level rather than field-complete.'
