The available segments in your DMP are made available by Piwik Pro Audiences via a REST-API. In your Kameleoon account, click Admin > Projects.

​
Global custom script

To insert the global custom script:
  • Click Configuration > General.
The Global custom script insert will link Kameleoon to Matomo. Any JavaScript code you add in this insert will be executed every time the page loads. This feature is usually used to add complex tracking code or integration to other solutions.
Copy and paste the code below into the Global script section: 
const getPiwikProSegments = (visitorID) => {
        const clientID = 'Replace this with your client_id from generated credentials';
        const websiteID = 'Replace this with your project_id';
        const xhr = new XMLHttpRequest();
        xhr.onload = function run() {
            if (this.status === 200) {
                Kameleoon.API.Data.setCustomData(
                    'Piwik Pro segments',
                    JSON.parse(xhr.response)
                );
            }
        };
        xhr.open('GET', https://customers.kameleoon.com/kameleoon/piwik/user/${visitorID}?id=${clientID}&website_id=${websiteID}, true);
        xhr.send();
    };

    Kameleoon.API.Core.runWhenConditionTrue(() => typeof _paq !== 'undefined', () => {
        _paq.push([function init() {
            getPiwikProSegments(this.getVisitorId());
        }]);
    });
Click Validate to apply the changes to your configuration.

Custom data

You then must create a new custom data. You will need:
  • your client_id & client_secret for generating Bearer Token (get Credentials).
  • your website_id.
Use the Activation API Method acquisition method. This code should be placed in the Save the values for the targeting condition associated with the custom data point section of the custom data (don’t forget to add your client_id and website_id). 
  let segmentPW = [];
     const clientID = 'Replace this with your client_id from generated credentials';
     const websiteID = 'Replace this with you website_id';
 

     const xhr = new XMLHttpRequest();
     xhr.onreadystatechange = function check() {
         if (this.readyState === 4) segmentPW = JSON.parse(xhr.response);
     };
     xhr.open('GET', [https://customers.kameleoon.com/kameleoon/piwik/segments/?id=${clientID}&website_id=${websiteID}](https://customers.kameleoon.com/kameleoon/piwik/segments/?id=$%7BclientID%7D&website_id=$%7BwebsiteID%7D), false);
     xhr.send();
     return segmentPW;
You will notice that in this code we call a Kameleoon Webservice (https://customers.kameleoon.com/kameleoon/piwik/), which uses the Piwik Pro API to get all segments. This call is needed to go through CORS policy issues. The custom data should be set to the list of and strings types; the scope is Page.

External Segment Sync for Server-side

If you would like to use Matomo segment data with one of our SDKs, you will need to follow the guidelines provided in each SDK documentation and use the method getRemoteData().
