### Native Ads: JSON <a href="#native-a-ds-json" id="native-a-ds-json"></a>

For native ads the **adm** parameter should contain a JSON encoded stsring like this:

```json
{
  "native": {
    "link": { "url": "https://s.ad-network.com/click.php?d=H4sIAAAAAAAAA1VQOW7DMBD8ihu3wh68VLpJ...qACaqb6E.TqO0AQAA" },
    "eventtrackers": [
      {
        "event": 1, 
        "method": 1, 
        "url": "https://s.ad-network.com/cimp.php?data=TVRjMk9UWXhPRGN3TVh4bFl6WTJaVFUyTURBek56WT...mM1Mjk5MWI4ZmM0YjQ-"
      }
    ],
    "assets": [
      { "id": 1, "title": { "text": "Ad Title" } },
      { "id": 2, "data": { "value": "Ad description" } },
      { "id": 3, "img": { "url": "https://static.ad-network.com/library/32167/image.jpg" } }
    ]
  }
}
```

### Push Notifications / In-Page Push Notifications: JSON <a href="#push-notifications--in-page-push-notifications-json" id="push-notifications--in-page-push-notifications-json"></a>

For Push Notification ads the adm parameter will contain a JSON encoded string like the following (note that we use the 'native' object to implement push notification ads). Width and height depend on the width and height coming from request. Currently supported dimensions are 192x192 and 720x480. One image asset per notification.

```json
{
  "native": {
    "link": {
      "url": "https://s.ad-network.com/click.php?d=H4sIAAAAAAAAA1VQOW7DMBD8ihu3wh68VLpJ...qACaqb6E.TqO0AQAA"
    },

        "required": 1,
        "img": {

## No Bid Response <a href="#no-bid-response" id="no-bid-response"></a>

To answer a bid request without making an actual bid, an HTTP response code 204 "No Content" will be sent.

## Win Notification <a href="#win-notification" id="win-notification"></a>

When the parameter **Bid Response Object -> Seat Bid Object -> Bid Object -> nurl** is in the bid response, a GET request must be performed to such URL.

## Billing Notification <a href="#billing-notification" id="billing-notification"></a>

When the parameter **Bid Response Object -> Seat Bid Object -> Bid Object -> burl** is in the bid response, a GET request is performed to that URL when the impression or click becomes billable (CPM or CPC, per the `btype` field). This allows the impression or click to be counted from the billable event rather than from pixel-based tracking.

If both `nurl` and `burl` are present, both should be called.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.exads.com/rtb/publishers/open-rtb/open-rtb-publishers-response-2p5.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
