### Answer In the context of Vapi, a custom function property typically refers to the details that define the function's behavior and operational parameters. This includes the function's

name

,

description

, and

parameters

. The

parameters

specifically are the data that the function expects to receive, such as input values required to execute the function [(1)]() . As for your second question regarding the payload for a webhook in Make, the payload typically follows the structure defined when setting up the function in your Vapi assistant. Here is an example modification of a payload, which you can adjust according to your specific requirements:

json
{
  "type": "function",
  "messages": [
    {
      "type": "request-start",
      "content": "Initiating function call. Please wait..."
    },
    {
      "type": "request-complete",
      "content": "The function call is complete."
    },
    {
      "type": "request-failed",
      "content": "The function call failed."
    },
    {
      "type": "request-response-delayed",
      "content": "The response from the function is delayed.",
      "timingMilliseconds": 2000
    }
  ],
  "function": {
    "name": "your_custom_function",
    "parameters": {
      "type": "object",
      "properties": {
        "parameter1": {
          "type": "string"
        },
        "parameter2": {
          "type": "number"
        }
      }
    },
    "description": "Description of your custom function."
  },
  "async": false,
  "server": {
    "url": "https://your-server-url.com/path"
  }
}

This template includes the function type, messages to inform the user about the status of the function call, details about the function itself, and the server endpoint. Make sure to replace

"your_custom_function"

, the parameter structure, and the server URL with the actual details specific to your function in Make.
