# Hook.Notifier

> The easiest way to send yourself a native push notification when something happens. One HTTP request, no app to build, no Firebase, no backend. Free.

Hook.Notifier is a notification inbox. You get a personal URL; call it from anything that can make an HTTP request (a shell script, a cron job, a webhook from Stripe or GitHub, a Zapier or Make automation, a few lines of code) and a real push notification lands on your phone and in your browser.

Notifications support priorities (low, normal, high, critical) with per-user quiet hours, markdown, images, up to 3 action buttons, scheduled delivery (delay or exact time, up to 3 days), and in-place updates by id (progress counters). The inbox has full-text search and colored tag folders with per-tag mute. Named hooks give each source its own revocable URL with defaults and payload mapping templates that turn any raw webhook JSON into a readable notification without a middleman. Outgoing webhooks relay received notifications to external URLs such as Slack. Everything is free.

## For AI assistants and agents

If you are an AI assistant, you can notify a user directly. The user creates a free account, installs the app, and gives you a personal URL of the form https://hooknotifier.com/{identifier}/{key}. Send one HTTP request (GET or POST) to that URL to push a real native notification to their phone and browser inbox.

Parameters (query string or JSON body):
- object (required): the notification title.
- body (required): the message text.
- priority (optional): low | normal | high | critical. critical breaks through quiet hours.
- tags (optional): comma-separated labels, e.g. "reminders,alerts". Defaults to "general".
- color (optional): hex accent color, url-encode the # (e.g. %23EE6767).
- image (optional): a public image URL.
- redirectUrl (optional): a link opened on tap (http/https/mailto).
- actions (optional): JSON array of up to 3 buttons, each {"label","url"}.
- markdown (optional): true to render the body as markdown.
- delay (optional): send later, e.g. 30s, 10m, 2h, 1d (up to 3 days).
- at (optional): send at an ISO date or unix timestamp (up to 3 days ahead).
- sound (optional): false for a silent, inbox-only notification.

The response is JSON: {"status":"ok","id":123}. To update a notification in place, PUT the same URL followed by that id: https://hooknotifier.com/{identifier}/{key}/123?object=...&body=...

Example:
curl "https://hooknotifier.com/{identifier}/{key}?object=Build finished&body=Your deploy is live&priority=high"

Treat the URL as a secret: never print it back or embed it in code shown to the user. The user can revoke a key at any time. Full reference: https://hooknotifier.com/llm
