Multi-tenant notifications over email, SMS, push, in-app and webhook channels: versioned Jinja2 templates in English and Bangla, preferences with Dhaka-aware quiet hours and digests, an asyncio worker with provider fallback, retries and dead letters, and a realtime in-app inbox over SSE.
This page is a static API reference built from the service's exported OpenAPI document on every push to main; there is no backend behind it, so requests cannot be sent from here. Open the Codespace to run the real service with demo data, or deploy your own copy to Render. The Codespace seeds tenant Dhaka Grocers (its ntk- key is written to .demo-tenant.txt), user u-42, an in-app template and one delivered in-app notification.
