If you want to take control of handling fraudulent impressions yourself, for example, redirecting them to different URLs based on the traffic source, the onResponse option will assist you.

Please note that this option is only available in JS check type integrations.

Option Activation

Request the activation of the onResponse option from your manager for your integration. Once enabled, implement its logic after activation.

After implementing the function, it will appear in the window.kmnr.onResponse field in the generated script code, which you can copy using the Copy button and place on your page within the <head> tag.

Signature

The function takes as argument object { fraud, block }, where fraud can have a value of 0 (legitimate impression) or 1 (bot impression), and block can have a value of 0 (legitimate impression) or 1 (click was blocked according to the integration settings)

function(response) {
    if (response.block == 1) {
        // blocked click
        window.location = 'some.url';
    } else if (response.fraud == 1) {
        // bot
        window.location = 'some.url';
    } else {
        // not a bot
        showAd();
    }
}

Interaction with Traffic-back URL

If you have an integration with both the onResponse and Traffic-back URL options enabled, keep in mind that onResponse takes precedence. In this case, the Traffic-back URL will be ignored.
