### Answer When setting up tools with Vapi, your assistant can perform various actions by invoking functions defined by you. The server URL you've set for the tools should handle these function calls. However, the function calls are made using HTTP POST requests, not GET requests [(1)]() [(2)]() [(3)]() . Here's an example of a tool configuration that fetches the weather for a given location:

json
{
  "type": "function",
  "messages": [
    {
      "type": "request-start",
      "content": "Checking the weather forecast. Please wait..."
    },
    {
      "type": "request-complete",
      "content": "The weather in location is"
    },
    {
      "type": "request-failed",
      "content": "I couldn't get the weather information right now."
    },
    {
      "type": "request-response-delayed",
      "content": "It appears there is some delay in communication with the weather API."
    }
  ],
  "function": {
    "name": "get_weather",
    "parameters": {
      "type": "object",
      "properties": {
        "location": {
          "type": "string"
        }
      }
    },
    "description": "Retrieves the current weather for a specified location."
  },
  "async": false,
  "server": {
    "url": "https://your-weather-api.com/weather"
  }
}

In this configuration: 1. **Function Name and Parameters**: Define the function name and parameters it accepts. 2. **Messages**: Customize the messages for different stages of the function call. 3. **Server URL**: Set the server URL where the POST request will be sent. Make sure your server at

webhook.site

is set up to handle POST requests and not GET requests.
