Hi Vapi Support – I’m having an urgent issue: {{user_email}} and {{user_phone}} are not being replaced with real values in the system prompt, although {{user_name}} works fine in the first message. This is affecting our live call experience. Please help ASAP!

Check your server's response to ensure the variable names exactly match those used in your system prompt. For example, your server should return:

{
  "assistantId": "your-assistant-id",
  "assistantOverrides": {
    "variableValues": {
      "user_name": "John Doe",
      "user_email": "john@example.com",
      "user_phone": "+1234567890"
    }
  }
}

{
  "assistantId": "your-assistant-id",
  "assistantOverrides": {
    "variableValues": {
      "user_name": "John Doe",
      "user_email": "john@example.com",
      "user_phone": "+1234567890"
    }
  }
}

Make sure the keys (user_email, user_phone) are spelled exactly as in your prompt and that they are not missing or null. This should resolve most variable replacement issues in Vapi assistants.

Hey! To help track down this issue, could you share: - The call ID - When exactly this happened (the timestamp) - What response you expected to get - What response you actually got instead
This would really help us figure out what went wrong!
