Apprise API

Apprise API is a free, open-source REST notification gateway that exposes the Apprise notification library through a network-accessible service. It allows applications, scripts, and monitoring systems to send messages to more than 150 supported notification services through a unified interface. A web-based configuration manager helps users create destinations, organize notification groups, and test delivery settings. Developers can target individual services or multiple recipients using configurable tags and identifiers. The platform supports message attachments, custom notification plugins, and persistent configurations. An Android companion application enables sending messages and files directly from a phone. Apprise API supports Docker deployment, HTTP Basic authentication, OpenAPI documentation, and Prometheus metrics. It can operate as a lightweight self-hosted service or part of larger automation infrastructure.
