Start Tracking
How Our Tracking Works
If the snippet is loaded on webpage, it will start tracking users immediately
Each incomming user has assigned unique ID called njuser
After njuser is assigned, snippet will continue tracking actions completed by user called events
Each unique event has its unique ID called event_id
In order to fully integrate with MyDataNinja we recommend you to save njuser and event_id on your side as well, So you can comminicate with us afterwards.
How To Get Data From Snippet
After snippet is loaded, the global scope variable is created called nj , you can use that variable to call some snippet methods.
If you look at the snippet, we call init method using following syntax nj.push(['init', {}]);. The reason why we use nj.push is because if script is not loaded yet, any call on nj method will result an error , but using push method everything will be called after loading
Always make sure that the method you are calling on nj does exist
How To Retreive User ID (njuser)?
After njuser has assigned to current visitor, you can call nj.getUserId() to retreive that njuser
const njuser = nj.getUserId();
console.log(njuser); // 1234567
How To Retreive Event ID?
After every event tracked by ninja, you can call nj.getLastEventId() to get latest event id occured on webpage.
When user snippet is loaded pageview event is called by default. If you call nj.getLastEventId() without throwing any other event, this will return an ID if that pageview event.
const event_id = nj.getUserId();
console.log(event_id); // 1234567
In order to get an event_id of event you have fired on your own, please see next section
