Managing Alert Channels

Channel Configuration Overview

Configure channels with flexible subscription and filtering options:

1. Create Alert Channel

   Choose your notification method and provide connection details

2. Configure Alert Types

3. Subscribe Checks

   Choose which checks and check groups use this channel

4. Test Integration

   Verify the channel works correctly with test notifications

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 or secret using {{NAME}} syntax. The channel UI also lets you promote an inline value to a secret without leaving the page.

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 or secret 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.

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