How to connect Circle and Vapi
Create a New Scenario to Connect Circle and Vapi
In the workspace, click the “Create New Scenario” button.

Add the First Step

Save and Activate the Scenario
After configuring Circle, Vapi, 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 Circle and Vapi integration works as expected. Depending on your setup, data should flow between Circle and Vapi (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
