# Notifications

> Notification architecture, settings model, delivery channels, and testing workflow in Radarboard.

# Notifications

Radarboard has a unified notification system that turns integration activity into a single event pipeline.

## What the system does

* ingests events from integrations, plugins, and webhook receivers
* deduplicates and persists them
* applies source preferences, quiet hours, snoozes, and custom rules
* batches non-critical events into digest windows
* delivers to in-app, desktop, webhook, and MCP channels

Critical events bypass batching and deliver immediately.

## Where settings live

Notification settings are intentionally split by responsibility.

### Integration modal

Per-integration notification behavior belongs in the integration detail modal.

That is where you configure:

* whether the integration emits notifications
* which preset it uses
* its digest window

This keeps source-specific behavior close to the service itself.

### Notifications settings page

The Notifications page is for global behavior:

* channels
* quiet hours
* rules
* webhooks

## Desktop notifications

Desktop notifications use the browser Notification API.

If the UI says:

```text theme={null}
Denied. Reset permission in browser settings.
```

the browser has already set notification permission to `denied` for the Radarboard origin.

The app cannot re-prompt in that state.

To fix it:

1. reset notification permission for `https://radarboard.localhost:1355`
2. refresh the page
3. enable the desktop toggle again

## Delivery channels

Current channels:

* `in_app`
* `desktop`
* `webhook`
* `mcp`

Email is intentionally deferred for a later pass.

## Webhooks

Inbound integration webhooks are documented separately:

* [Local Webhook Development](/developer-guide/local-webhooks)

Outbound webhook delivery is configured in the Notifications settings page.

## Rules

Rules let Radarboard add or override routing for matching events.

They support:

* source filter
* event type glob
* minimum severity
* optional structured condition
* delivery channels

## End-to-end test checklist

1. trigger an integration event
2. confirm the bell badge updates
3. verify the dropdown and panel show the event
4. mark the event read or dismissed
5. test an outbound webhook endpoint from settings
6. add a rule and confirm it changes routing
7. test desktop notifications with the tab in the background
