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.
