Save and Activate the Scenario
After configuring Harvest, Sendgrid, and any additional nodes, don’t forget to save the scenario and click "Deploy." Activating the scenario ensures it will run automatically whenever the trigger node receives input or a condition is met. By default, all newly created scenarios are deactivated.
Test the Scenario
Run the scenario by clicking “Run once” and triggering an event to check if the Harvest and Sendgrid integration works as expected. Depending on your setup, data should flow between Harvest and Sendgrid (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
