Slack Integration: Incident Notifications

​

Prerequisites

• A Slack workspace
• Permission to install apps in your Slack workspace

​

Step-by-Step Setup

​

1. Navigate to Integrations

In your Corelayer dashboard, go to the Integrations page.

​

2. Add Slack Integration

Click the Add Integration button and select Slack from the list of available integrations. Click Connect to Slack.

​

3. Authorize Slack Connection

You’ll be redirected to Slack’s OAuth authorization page:

1. Select the workspace you want to connect
2. Review the permissions Corelayer is requesting
3. Click Allow to grant access

​

4. Verify Connection

Once redirected back to Corelayer, your Slack integration should appear as Connected in the integrations dashboard.

​

5. Configure Channels

Select which Slack channels Corelayer should send notifications to:

• Choose existing channels from the dropdown
• Configure notification preferences per channel, including routing by environment and severity

​

Route Notifications by Environment and Severity

Corelayer infers the environment associated with an issue and considers it during analysis. You can use environment and severity to route issue notifications to the Slack channels that should receive them. Open Integrations → Slack → Settings. Under Alerts → Routing rules, expand an existing rule or click Add rule. Use Environment and Severity to select the matching criteria, then choose the destination Channel. Rules are checked from top to bottom, and the first matching rule sends the alert. For example:

• Route critical production issues to your on-call channel
• Route staging issues to a staging channel
• Route development issues to a development channel

Choose the environments and severities that each team needs to follow. Make sure the Corelayer bot has been invited to every destination channel.

​

What Corelayer Can Do With Slack

Once connected, Corelayer will:

• Send real-time notifications when issues are detected
• Post debugging summaries and root-cause analysis to your channels
• Deliver digest messages with aggregated issue reports
• Create scheduled tasks from Slack, including recurring checks and one-shot reminders
• Route issue notifications to your configured channels based on environment and severity

​

Scheduled Tasks From Slack

You can ask Corelayer in Slack to run a task on a schedule and post the result back to the same channel. Examples:

• “Every weekday at 9am, post a summary of open critical issues”
• “Every hour, check whether new high-severity issues appeared”
• “Remind me in 20 minutes to check this issue again”

Corelayer supports recurring schedules, fixed intervals, and one-shot reminders. If your request uses a local time, include the timezone so Corelayer can schedule it correctly. Scheduled runs are read-only: they can investigate, summarize, and report back to Slack, but they cannot change settings or create additional scheduled tasks.

​

Managing Your Integration

​

Disconnecting

To disconnect your Slack integration:

1. Navigate to Settings > Integrations
2. Find your Slack integration and click Uninstall
3. Confirm the uninstallation
4. Optionally, remove the Corelayer app from your Slack workspace settings

​

Troubleshooting

​

Integration Not Working?

• Verify the Corelayer app is installed in your Slack workspace
• Ensure the bot has been invited to the channels you’ve configured
• Check that your Slack workspace permissions allow third-party app installations
• If an issue notification is missing, check that its environment and severity match the routing criteria for the channel
• Try reinstalling the integration if notifications are not appearing
