The Manual trigger fires when you click **Run manually** inside the workflow in the Composer. Use it to test your workflow before connecting a live trigger, or to run a one-off operation that doesn't need to be automated. ## Configuration No setup required. Open the workflow in the Composer and click **Run manually** in the toolbar. ## Available variables Manual runs do not inject contact or call data automatically. If your workflow actions use variables like `{phone_number}` or `{name}`, provide test values using custom variables before running. See [Variables](/workflows/variables) for how to define custom variables. ## Use case You've built a workflow that sends a Slack notification and creates a HubSpot deal. Before connecting it to a live End of Call trigger, run it manually to confirm both actions execute and the variable values resolve correctly. ## Next steps Choose what Wave Runner does after the trigger fires.
