After installing it you get webhook URLs of the form `https://YOUR-ENDPOINT/v1/` (one for all devices, one per device). POST plain text or JSON to send a push; GET with query parameters also works. Alternatively POST to `https://YOUR-ENDPOINT/v1/send` with `Authorization: Bearer `. JSON fields: title, subtitle, message, thread_id, sound, volume, open_url, image_url, icon_url, expiration_date, filter_criteria, interruption_level (passive | active | time-sensitive | critical). ## Pages - [Landing page (markdown)](https://beep-now.pages.dev/index.md): this page as plain markdown - [Docs](https://beep-now.pages.dev/#how): webhook format, payload fields, examples, delivery behaviour - [Learn](https://beep-now.pages.dev/#integrations): integration guides (cURL, GitHub Actions, Python, JavaScript, Home Assistant, n8n, Shortcuts, Zapier, Claude Code, Codex, Copilot CLI, Uptime Kuma) ## Optional - [App Store](#): download the app (link coming soon) - [Privacy policy](https://beep-now.pages.dev/#faq)
