Submit user feedback (like/dislike rating and optional text comments) for a specific message. This endpoint supports both registered users (Auth0 JWT) and guest users (device-based authentication), making it accessible during free trial flows.

​
Authentication Methods

Unlike other conversation endpoints, this route accepts two authentication methods:
  1. Auth0 JWT (Registered users)
    • Header: Authorization: Bearer <token>
    • Standard authenticated flow
  2. Device-based (Guest users)
    • Headers: x-device-id, x-user-id, x-platform
    • Same authentication as /api/v1/ai/chat
    • Enables feedback during trial/guest sessions

​
Use Cases

  • Thumbs up/down on AI responses
  • Report inaccuracies with text feedback
  • Track user satisfaction for model improvements
  • A/B testing different prompts or models

    "code": "UNAUTHORIZED"
  }
}

​

  • rating must be exactly 1 or -1 (no other values accepted)
  • feedback is optional but limited to 1000 characters
  • messageId must be a valid 24-character MongoDB ObjectId
  • User must own the conversation containing the message

​
Notes
