Pixel/JS integration¶

To start setting the integration - go to "Add Integration" tab:

Then, you see the Integration wizard:

• Step 1: Select what you are going to score - for example, Impressions

• Step 2: Select "Pixel/Javascript" to set the integration

• Step 3: Give the name to your integration. The name will be used in your FraudScore report to help you find it among other integrations, if you have it:

• Step 4: Review all the settings and click "Create Integration". Note - if you want to make changes - click the needed step in the integration wizard:

To Send Only Impressions:

Insert the pixel into the target page code:

<img src="https://check.fraudscore.ai/px/<YOUR_KEY>.png">

You may send us additional parameters to group your data in the FraudScore report, e.g. partner, offer, affsub, etc.

<img src="https://check.fraudscore.ai/px/<YOUR_KEY>.png?affiliate_id=123&offer_id=456">

To Receive Request Results (fraud reasons) to use in code:

Insert the JS call into the target page code:

<script src="https://check.fraudscore.ai/js/<YOUR_KEY>.js"></script>

You may send us additional parameters to group your data in the FraudScore report, e.g. partner, offer, affsub, etc.

<script src="https://check.fraudscore.ai/js/<YOUR_KEY>.js?affiliate_id=123&offer_id=456"></script>

Аfter loading the script, the result will be available in the window.fraudscore variable.

<script>
  if (window.fraudscore && window.fraudscore.reasons && window.fraudscore.reasons.length){" "}
  {
    // some code that will be run if fraudulent requests are detected
  }
</script>

Also you can use the async option to get the result asynchronously:

<script async src="https://check.fraudscore.ai/js/<YOUR_KEY>.js"></script>

For professional/custom integrations using Beacon API for requests:

The request will be sent even if a tab is closed.

<script>
  (function (a) {
    var u = 'https://check.fraudscore.ai?';
    for (var k in a) u = u + k + '=' + encodeURIComponent(a[k]) + '&';
    navigator.sendBeacon(u);
  })({
    key: 'YOUR_KEY',
    // other params e.g. partner, offer, affsub and so on.
  })
</script>
