Set the Linear trigger as “Comment added”

Add the Linear trigger to initiate your playbook's actions each time a comment is added.

To do this, click "Add trigger" in your playbook. Select the "Comment added" trigger option from the dropdown menu under Linear. It will enable your playbook to automatically identify newly added comments and trigger necessary actions.

If you still need to connect your Linear account to Relay.app, a prompt will guide you through the connection process.

Add the “Send message” step in Slack

Integrate Slack automation into your playbook to ensure that you receive timely updates each time a comment is added in Linear.

Select "Add Step" and then find the "Send message" automation for Slack. Enter all the required details, including the sender's name, the Slack channel for updates, and the message body containing detailed information.

If you still need to connect your Slack account to Relay.app, you will be prompted to complete that connection. Ensure that you allow the necessary permissions for Relay.app to send messages through your Slack account.

Activate your playbook

Activating your playbook is the last step in the process. Once you turn it on, it will automatically send Slack messages to a channel each time a comment is added in Linear without requiring manual intervention.

To activate your playbook, click the toggle button at the header. Before activating, we recommend performing a test run of your playbook to ensure all the steps work seamlessly together.
