By default, to verify click-through links for Meta Redirect-type integrations, we use a clickworker, a special page on the Kaminari Click domain, which checks the user and then redirects good users to the target link, and bots to traffic-back URL, if the corresponding option is enabled. This approach is as simple and convenient as possible, but has a number of disadvantages.

If suddenly a technical problem occurs on our server, the redirect breaks down and your traffic will be lost.
Redirects between different sites are slower than within one site, so a redirect through our clickworker can increase the percentage of non-revenue to the target link.
You may feel uncomfortable that a third party is included in the redirect chain.

To solve these problems, we suggest downloading the clickworker and hosting it on your server. It needs to be updated once a day because we regularly make changes to the scripts.

Please note that this option is only available for Meta Redirect-type integrations.

Option Activation

Request the activation of the Download Clickworker option from your manager for your integration. Once enabled, a download link will appear in the integration for you to retrieve the clickworker.

Templates

The curly brackets in the link contain templates, and they will be passed into the code as they are.

https://kaminari.space/v1/click?kmnrKey=XXXXXXXXX&kmnrId={kmnrId}&sub1={sub1}&sub2={sub2}&sub3={sub3}&sub4={sub4}&sub5={sub5}&sub6={sub6}&sub7={sub7}&u={clickUrl}&download

When delivering the clickworker to the user, you can dynamically replace the templates with current data.

Templates description

kmnrId	kmnrId, generated during the ping at https://kaminari.systems/v2/ping. Needed for linking clicks if the S2S ping option is enabled.	Required if the option S2S ping is enabled

Headers

For the clickworker to function correctly, it must send the following headers to the user's browser:

access-control-allow-origin: *
access-control-allow-methods: GET, POST, OPTIONS
access-control-allow-headers: X-Requested-With, Cache-Control, Content-Type
accept-ch: Width, Viewport-Width, DPR, Device-Memory, Downlink, RTT, ECT, Save-Data, Sec-CH-UA-Arch, Sec-CH-UA-Bitness, Sec-CH-UA-Mobile, Sec-CH-UA-Model, Sec-CH-UA-Platform, Sec-CH-UA-Platform-Version, Sec-CH-UA, Sec-CH-UA-Full-Version

Example implementation

Below is an example of the simplest implementation of a clickworker on your side using PHP.

Let's say that you own a website my-site.com and people come to you through links like this:

https://my-site.com/click.php?utm_source=1&utm_campaign=123&utm_click_id=93652664834&target=https%3A%2F%2Fgoogle.com

And you want Kaminari Click to check the user for fraud and redirect to the target link (in this case, google).

Making a link

You decided that you will take the data directly from the GET parameters and that utm_source will be written in sub1, utm_campaign in sub2 and utm_click_id in sub3.

Next, in your integration settings you need to copy the link for clickworker downloading and replace the templates you need, that is, {sub1}, {sub2}, {sub3}, {clickUrl}, the rest can be deleted.

As a result, you will get a link like this:

https://kaminari.space/v1/click?kmnrKey=XXXXXXXXX&sub1=<?=$_GET['utm_source']?>&sub2=<?=$_GET['utm_campaign']?>&sub3=<?=$_GET['utm_source_id']?>&u=<?=$_GET['target']?>&download

Downloading a clickworker

Using the resulting link, download the clickworker and save it to the file clickworker.php

Then you need to create a click.php file, put the headers in it and include clickworker.php

<?php

    header('Access-Control-Allow-Origin: *');
    header('access-control-allow-methods: GET, POST, OPTIONS');
    header('access-control-allow-headers: X-Requested-With, Cache-Control, Content-Type');
    header('accept-ch: Width, Viewport-Width, DPR, Device-Memory, Downlink, RTT, ECT, Save-Data, Sec-CH-UA-Arch, Sec-CH-UA-Bitness, Sec-CH-UA-Mobile, Sec-CH-UA-Model, Sec-CH-UA-Platform, Sec-CH-UA-Platform-Version, Sec-CH-UA, Sec-CH-UA-Full-Version');
    
    include_once('clickworker.php');

The both files must be uploaded on the website.

Testing

To check, go to the link in your browser:

https://my-site.com/click.php?utm_source=1&utm_campaign=123&utm_click_id=93652664834&target=https%3A%2F%2Fgoogle.com

Great job! The redirect worked and you ended up on Google’s website.

Time to check the statistics. Excellent result. The click was counted, the tags were placed correctly.
