It sounds like you might be looking at a placeholder or default value in your Vapi Dashboard. The server URL should be a web address where Vapi can send HTTP requests. If the fields for the Server URL and Server URL secret are empty, you will need to provide the URL of the server where your voice application is hosted.
If you have a web application that's designed to work with Vapi, the server URL will be the endpoint in your application that's set up to receive and respond to webhooks from Vapi. This URL is something you or your development team would have created as part of your application's backend.
If you do not have this URL, you will need to set up a server endpoint that can handle requests from Vapi. This typically involves writing server-side code to process the webhooks and configuring your server to be accessible over the internet.
Once you have your server set up and you know the URL, you should enter it into the Server URL field in your Vapi Dashboard. The Server URL secret is a security measure to ensure that the requests to your server are coming from Vapi; you can generate a secret and provide it in both Vapi and your server configuration for validation.
If you're still unsure about how to proceed or if you need technical assistance with setting up your server, please ask support for more info on this.
