This n8n automation connects your Typeform forms with Vapi AI, allowing you to immediately call new form respondents with a personalized message from a Vapi AI assistant, as soon as a form submission is received. 🧾 Requirements Typeform A Typeform account Typeform personal access token and credentials enabled in n8n A Typeform form published that includes a phone number field Vapi A Vapi account with credit A connected phone number to make calls An assistant created and ready to make calls Your Vapi API key 🔗 Useful Links n8n Typeform Credentials Setup Vapi Docs 🔄 Workflow Breakdown 1. Trigger: Typeform Submission Triggered when a new response is submitted to your Typeform. The form must include a phone number field. 2. Wait 2 Minutes Adds a short delay before proceeding. Useful to ensure form data is fully synced or to give time for related automations. 3. Set Vapi Fields (Manual Step) Set the required fields for the Vapi API call: phone number id - connected in Vapi assistant id - the assistant enabled in the call Vapi API key - your secure API key 4. Start Outbound Vapi Call Sends a POST request to https://api.vapi.ai/call Payload includes: Respondent’s phone number (from Typeform) Vapi assistant id Vapi phone number id to initiate the call ✏️ Template Customization Guidance How to Adapt for Your Specific Needs Personalize the Call Content:** Include additional fields in your Typeform (e.g., first name, interest, location). In n8n, map these form fields into the payload sent to Vapi. Update your Vapi assistant’s prompt/script to reference these variables for a highly personalized experience. Conditional Call Logic:** Use n8n's logic nodes (e.g., IF, Switch) to, for example: Only trigger calls if a respondent checks a checkbox (e.g., consent or interest). Use a different Vapi assistant or phone number based on responses (e.g., language preference or location). Advanced Routing:** Configure the workflow to choose different assistants, phone numbers, or call scripts based on the respondent’s answers. Store assistant IDs or numbers as environment variables or reference them from a lookup table for dynamic selection. 📞 Examples: Using Form Data to Personalize Calls Greeting by Name:** If your Typeform collects first_name, map it into the Vapi payload. Your assistant script can begin, "Hi {{first_name}}, thanks for your interest in XYZ!" Custom Message Based on Product Interest:** Add a product_interest field in Typeform. Pass its value to Vapi and have the assistant mention the product, e.g., “I see you’re interested in our Premium Plan…” Reference Appointment Times or Locations:** Collect appointment_time and/or city fields, and tailor the call to reconfirm booking details using these inputs. 🛠️ Troubleshooting & Tips Call Not Triggering:** Ensure your Typeform webhook connection and credentials are correctly set up in n8n. Check that your workflow is active and the trigger node is configured for the correct form. Invalid Phone Number Format:** Vapi requires numbers in full international format (e.g., +11234567890). Use n8n expressions to clean or verify the incoming number if needed. Missing Data in the Call:** Confirm that additional fields (e.g., first_name) exist in the Typeform response and that your mapping in n8n matches the exact field names. Failed API Call:** Double-check your Vapi phone number id, assistant id, and API key. Use n8n’s execution logs to inspect the payload sent to Vapi for debugging. Duplicate Calls:** If your Typeform allows multiple submissions, add logic in n8n to check for and avoid duplicate calls, for example by maintaining a record of called numbers. 🙋♂️ Need Help?
