Set the Todoist trigger as “Task completed”

Add the Todoist trigger to initiate your playbook's actions whenever tasks are completed.

To do this, click "Add trigger" in your playbook. Select the "Task completed" trigger option from the dropdown menu under Todoist. It will enable your playbook to automatically identify newly completed tasks and trigger necessary actions.

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

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