Set the Trello trigger as “New list added”

Add the Trello trigger to initiate your playbook's actions every time a new list is added to a board.

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

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

Add the “Send DM” step in Slack

Integrate Slack automation into your playbook to ensure that you receive timely updates every time a new list is added to a Trello board.

Select "Add Step" and then find the "Send DM" automation for Slack. Enter all the required details, including the receiver's name, 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 direct messages through your Slack account.

3

Activate your playbook

Activating your playbook is the last step in the process. Once you turn it on, it will automatically send Slack direct messages every time a new list is added to a Trello board 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.
