Native Ads: JSON
For native ads the adm parameter should contain a JSON encoded string like this:
{
"native": {
"link": { "url": "https://mysite.com/landingpages/mypage" },
"eventtrackers": [
{
"event": 1,
"method": 1,
"url": "https://myEventTracker1.com"
}
],
"assets": [
{ "id": 1, "title": { "text": "Ad Title" } },
{ "id": 2, "data": { "value": "Ad description" } },
{
"id": 3,
"img": {
"url": "https://mysite.com/images/myad.jpg",
"w": 300,
“h”: 300,
}
}
]
}
}
Push Notification Ads: JSON
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.
{\"native\":{\"link\":{\"url\":\"http:\/\/mysite.com\/landingpages\/mypage\"},\"assets\":[{\"id\":1,\"required\":1,\"img\":{\"url\":\"http:\/\/mysite.com\/images\/myad.jpg\",\"w\":720,\"h\":480}},{\"id\":2,\"title\":{\"text\":\"Ad Title\"}},{\"id\":3,\"data\":{\"type\":2,\"value\":\"Ad description\"}}]}}
Which is based on the following JSON object:
{
"native": {
"link": {
"url": "http://mysite.com/landingpages/mypage"
},
"assets": [
{
"id": 1,
"required": 1,
"img": {

"w": 720,
"h": 480

"title": {
"text": "Ad Title"
}
},
{
"id": 3,
"data": {
"type": 2,
"value": "Ad description"
}
}
]
}
}

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