  title: Courier Audiences API
  description: 'Courier is notification infrastructure that orchestrates transactional and product messaging across email, SMS, push, chat, and an in-app inbox from a single REST API. This document models the primary public endpoints under the base URL https://api.courier.com: sending notifications (Send), inspecting sent messages, managing lists, user profiles, preferences, device tokens, notification templates, brands, automations, audiences, tenants, bulk jobs, audit events, and translations. All requests are authenticated with a Bearer API key. Endpoint paths are grounded in Courier''s published API reference; request and response bodies are modeled and simplified.'
