Layer’s notification system lets you route alerts to the right people through the channels they already use. You can configure notification channels and rules in Settings → Notifications.

​
Channels

Layer supports three notification channels: You can create multiple channels of each type — for example, separate Slack channels for IT alerts and finance alerts.

​
Webhook security

Webhook notifications include an x-webhook-signature header containing an HMAC-SHA256 signature of the request body, computed using your shared secret. Verify this signature on your end to confirm the notification came from Layer.

​
Notification rules

Rules connect events to channels. Each rule specifies:
  • Event type — what triggers the notification.
  • Channel — where the notification is delivered.
  • Enabled/disabled — toggle rules on or off without deleting them.
You can create multiple rules for the same event to send notifications to different channels simultaneously.

​
Event types

Start with the events that matter most to your team. You can always add more rules later without affecting existing notifications.

​
Set up notifications

1

Create a channel

Go to Settings → Notifications and click Add channel. Choose the channel type (email, Slack, or webhook) and provide the required configuration.
2

Add notification rules

For each event you want to be notified about, click Add rule, select the event type and the channel, then save.
3

Test the channel

Use the Send test button to verify your channel is configured correctly before relying on it for production alerts.
Email notifications require the Starter plan or above. Slack and webhook channels require the Growth plan or above.
