i'm trying to have it be able to communicate well but just using my system prompt for the voice call isnt cutting it. even things like {{name}} arnet working, not sure how i configure this, cant find docs other than in call text stuff.. TIY

To make your agent use variables like

{{name}}

in text chat, you need to pass them in your chat request using the

assistantOverrides.variableValues

field. Here’s a concrete example:

json
{
  "assistantId": "your-assistant-id",
  "input": "I need help with my account",
  "assistantOverrides": {
    "variableValues": {
      "name": "Alex"
    }
  }
}

Make sure your system prompt references

{{name}}

exactly, and pass the value as shown above for it to work in chat responses ([see docs](https://docs.vapi.ai/chat/quickstart#pass-variables-in-your-chat-request)). Source: - [Chat quickstart](https://docs.vapi.ai/chat/quickstart)

If you would like to use dynamic variables in your calls, please refer to the documentation:
