# Notifications

oncost sends alerts to Slack so your team stays informed without checking the dashboard.

## Setting up Slack

1. Go to **Settings > Notifications**
2. Click **Add Destination**
3. Select **Slack** and authorize oncost to post to your workspace
4. Choose a channel (e.g., `#cost-alerts`)
5. Click **Save**

## Alert types

### Real-time alerts

Sent immediately when triggered:

* **Anomaly detected** -- unusual spending pattern found
* **Budget warning** -- budget approaching or exceeding limit
* **Connection error** -- a provider connection has failed

### Weekly digest

A rich summary delivered to Slack on a schedule:

* Total spend this week vs. last week (% change)
* Top 3 cost movers (up and down)
* Budget status summary
* Unresolved anomaly count
* Deep link to the oncost dashboard

Configure the digest per destination:

1. Toggle **Enable weekly digest** on the destination card
2. Set **delivery day** and **time** (default: Monday 9am)

## Managing destinations

Each destination can be configured independently:

* Enable/disable real-time alerts
* Enable/disable weekly digest
* Set digest delivery schedule
* Delete the destination

## Digest preview

The notification settings page shows a preview of what the Slack message will look like, so you know exactly what your team will see.
