The VAPI URL you need to add to the VAPI module in Make.com (formerly Integromat) would typically be the URL of the server where your VAPI application is hosted. If you're using VAPI, you should have a publicly accessible URL pointing to your HTTP endpoint where VAPI can send events.
If you're developing locally, you'll need to use a service like ngrok to expose your local server to the internet. Once you have set up your local server and made it publicly accessible, you will receive a URL from the service you're using, which you can then use in the VAPI module in Make.com.
If you need further assistance with setting up your server URL or have specific questions about integrating with Make.com, please let me know, and I'll be happy to help!
