This page covers the settings that control how Blnk sends outbound notifications to Slack and to your own HTTP endpoints.
***
## Notification settings
Use the `notification` object to configure Slack incoming webhooks and a generic application webhook. You can set either integration alone, or both at the same time.
```bash blnk.env theme={"system"}
BLNK_SLACK_WEBHOOK_URL=
BLNK_WEBHOOK_URL=
BLNK_WEBHOOK_HEADERS={}
```
```json blnk.json theme={"system"}
{
"notification": {
"slack": {
"webhook_url": ""
},
"webhook": {
"url": "",
"headers": {}
}
}
}
```
| | Description | Default |
| :----------------------- | :----------------------------------------------------------------------------------------- | :------ |
| `BLNK_SLACK_WEBHOOK_URL` | Slack incoming webhook URL used for team alerts. | None |
| `BLNK_WEBHOOK_URL` | HTTPS endpoint that receives Blnk event notifications. | None |
| `BLNK_WEBHOOK_HEADERS` | JSON object of extra HTTP headers sent with webhook requests (for example authentication). | `{}` |
### `BLNK_SLACK_WEBHOOK_URL`
When set, Blnk can post messages to the Slack channel associated with the incoming webhook.
To create a webhook URL, follow Slack’s guide: [Sending messages using incoming webhooks](https://api.slack.com/messaging/webhooks).
Treat Slack webhook URLs like secrets. Anyone with the URL can post to your channel, so store them in a secret manager or environment variables, not in version control.
### `BLNK_WEBHOOK_URL`
When set, Blnk delivers notifications to your application at this URL. Use this when you want to trigger workflows, sync internal services, or custom alerting outside of your ledger.
