# Alert Channels

> Configure notification channels to receive alerts when checks fail, degrade, or recover. Choose from email, Slack, webhooks, PagerDuty, SMS, and custom integrations.

## Using variables and secrets in channel configs

Any literal-secret field in an alert-channel configuration — webhook URL, API key, bearer token, PagerDuty service key, and so on — accepts a reference to an account [environment variable](/platform/variables) or [secret](/platform/secrets) using `{{NAME}}` syntax. The channel UI also lets you promote an inline value to a secret without leaving the page.

<Note>
  **Using environment variables and secrets in this channel's config**

  Any literal-secret field in this alert channel — webhook URL, API key, bearer token, service key, etc. — accepts a [variable](/platform/variables) or [secret](/platform/secrets) reference using the familiar Handlebars syntax: `{{MY_VARIABLE}}`.

  You can also promote a value to a secret directly from the field: type the literal value, click the lock icon next to the input, and choose a name. The value is stored as an encrypted account secret and is never re-displayed in the UI.

<Tip>
  Use Checkly's alert notification log to track delivery success rates and identify any channels that frequently fail to deliver notifications.
