### Answer To include custom fields such as names in your Vapi assistant's prompts, you can use dynamic variables. These variables allow you to personalize the assistant’s messages dynamically. You can format these variables within double curly braces, like

{{variableName}}

, and set their values when initiating the call. Here’s an example on how to set the assistant’s first message using a dynamic variable for a name:

json
{
  "variableValues": {
    "name": "John"
  }
}

This configuration will replace

{{name}}

in any of your assistant's messages with "John" [(1)]() . For more information on how to utilize dynamic variables in your Vapi assistant, refer to the section on dynamic variables in the documentation .
