​
Body

​
bid_id
string
required
The bidId from the original bid response. Identifies which impression the feedback is for. User, publisher, campaign, and product information is resolved server-side from the impression data.
​
feedback_type
string
required
User’s feedback signal. Must be "positive" or "negative".
​
feedback_text
string
Optional free-text feedback from the user (max 1000 characters). Useful for “tell us why” flows on negative feedback.

}

// No response body (HTTP 204 No Content)

​
Behavior

  • One feedback per impression — duplicate submissions for the same bid_id return 204 silently (no error, no overwrite).
  • Impression must exist — the bid_id must correspond to a tracked impression. If the impression has expired or was never recorded, the endpoint returns 404.
  • Server-side enrichment — user, publisher, campaign, and product information is resolved automatically from the impression. You only need to send the bid_id.
  • No authentication required — this endpoint is called from the client side (browser or mobile app) and does not require an API key.

Integration

Add a thumbs up / thumbs down UI next to each ad. When the user taps, fire a single POST request: 
// iOS (Swift)
func sendFeedback(bidId: String, type: String) {
    guard let url = URL(string: "https://ssp.thrads.ai/api/v1/tracking/feedback") else { return }
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    request.httpBody = try? JSONSerialization.data(withJSONObject: [
        "bid_id": bidId,
        "feedback_type": type
    ])
    URLSession.shared.dataTask(with: request).resume()
}

// Web (JavaScript)
async function sendFeedback(bidId, type) {
  await fetch("https://ssp.thrads.ai/api/v1/tracking/feedback", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({
      bid_id: bidId,
      feedback_type: type,
    }),
  });
}
