Auto-Call New Typeform Submissions with Vapi Voice Assistant

This n8n workflow seamlessly connects Typeform form submissions to Vapi's AI voice platform, triggering an immediate personalized phone call to respondents as soon as they submit their details. Ideal for businesses seeking real-time engagement, it captures phone numbers from forms and dials them using a custom Vapi assistant, delivering scripted messages, answering questions, or qualifying leads on the spot.

The workflow starts with a Typeform trigger on new submissions, followed by a 2-minute wait for data sync. It then sets essential Vapi parameters (phone ID, assistant ID, API key) before sending a POST request to Vapi's API to initiate the outbound call with the respondent's number. This ensures reliable, hands-free follow-up without manual intervention.

Benefits include boosted response rates, higher conversion from leads, and scalable personalization via AI voices. Use cases span sales outreach (post-demo interest), customer support (survey feedback calls), appointment booking confirmations, or event registrations—perfect for marketing teams, sales reps, and service providers aiming to stand out with proactive voice interactions.

Setup requires Typeform credentials, a published form with phone field, Vapi account with credits, connected phone, assistant, and API key. Customize easily for different assistants or delays.
