Trigger outbound Vapi AI voice calls from new Jotform submissions

This workflow connects JotForm submissions to Vapi AI, triggering a personalized outbound call via an AI voice assistant immediately after a user submits your form.

Requirements

JotForm

• A JotForm account
• JotForm API credentials enabled in n8n
• A published JotForm form with a phone number field

Vapi

• A Vapi account with credit
• A connected phone number for making calls
• An assistant created and ready for outbound calls
• Your Vapi API key

Workflow Steps

1. JotForm Trigger

• Starts the workflow when a new form submission is received.

2. Information Extractor

• Formats the phone number with a +, country code, and full number (e.g., +391234567890) for compatibility with Vapi.

4. Set Fields for Vapi

• Configure these fields:
  • phone_number_id: ID of the Vapi number used for the call
  • assistant_id: ID of the Vapi assistant
  • api_key: Your Vapi API key

5. Start Outbound Vapi Call

• Sends a POST request to https://api.vapi.ai/call with:
  • The formatted phone number
  • All required Vapi fields
  • Any additional info mapped from the form, for personalization

Customization

• Add more form fields: Include extra data (such as name, appointment time) and add to the Vapi payload.
• Conditional logic: Use n8n filter nodes to control if/when calls are made.
• Dynamic assistant selection: Route submissions to different assistants or numbers based on user responses.

Notes

• Ensure phone numbers are formatted correctly in the extractor node to prevent call errors.
• Any field from your form can be passed in the API payload and used in the assistant's script.
