  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.
