Save and Activate the Scenario

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

Most powerful ways to connect Formstack and Vapi

Formstack + Vapi + Slack: When a new form submission is received in Formstack, Vapi analyzes the text for sentiment. If the sentiment is negative, a message is posted to a specified Slack channel.

Vapi + Formstack + Google Sheets: When a phone call is transcribed by Vapi, the call details are logged into Formstack using form fields. Subsequently, the Formstack submission data is added as a new row in Google Sheets.
