Run the scenario by clicking “Run once” and triggering an event to check if the Harvest and Google Calendar integration works as expected. Depending on your setup, data should flow between Harvest and Google Calendar (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
