WARNING
Barion Pixel will launch very soon.

Barion Pixel

The Barion Pixel is JavaScript code that allows you to track visitor activity on your website. It works by loading a JavaScript function which you can use whenever a site visitor takes an action that you want to track (this action is called an event).

In order to implement the Pixel, you will need:

  • access to your website's HTML code base
  • your Barion Pixel ID that you can access from your Barion Wallet

By default, the Pixel will track pages visited, and the devices your visitors use. In addition, you can use the Pixel's JavaScript function to track other events that are associated with webshop usage and e-commerce. Without collecting the consent of the website visitor you must still use the Barion Pixel on your website for fraud management purposes. (Tracking visitor behavior for the purposes of preventing fraud is considered a legitimate interest of Barion and the merchant in contract with Barion). The implementation of the base code is considered mandatory for using the Barion Smart Gateway.

Implementing the base code

Implementing the base code is not only required for you to be considered for special offers relating to the Barion Pixel, but also for using the Barion Smart Gateway at all. This is based on the fact that both Barion and you as the website owner have a legitimate interest in fraud management, and the data provided by the Barion Pixel greatly helps these efforts. This, as a legitimate interest case, is fully compliant with the GDPR, and must be implemented independently of any consent management software that your site may use.


Init (init)

  • User intent: View pages on your site
  • To be implemented at: Every page load, in the document head tag
  • Why do we need this: This provides very basic information on user sessions, and can be implemented very easily

To use the Pixel, you need to add the following code (referred to as the base code) between the opening and closing <head> tags on every page of your site. Most developers add it to their website's persistent header, so that it appears automatically on all loaded pages. Be sure to insert your unique Barion Pixel ID at both locations in the provided code example.

Placing the code within your <head> tags reduces the chances of browsers or third-party code blocking the Pixel's execution. It also executes the code sooner, increasing the chance that your visitors are tracked before they leave your page. Sending the data happens asynchronously in the client's browser so that it does not affect user experience.


Implementation of the base code 

   
        <script>
            (function(i,s,o,g,r,a,m){i['BarionAnalyticsObject']=r;i[r]=i[r]||function(){
            (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
            m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
            })(window, document, 'script', 'https://pixel.barion.com/bp.js', 'bp');

            // send page view event
            bp('init', 'addBarionPixelId', '[YOUR BARION PIXEL ID GOES HERE]');
        </script>

        <noscript>
            <img height="1" width="1" style="display:none" src="https://pixel.barion.com/a.gif?__ba_pixel_id=[YOUR BARION PIXEL ID GOES HERE]&ev=contentView&noscript=1"/>
        </noscript>


Heartbeat (heartbeat)

  • User intent: Browse your site
  • To be implemented at: No further implementation needed beyond the init event
  • Why do we need this: This provides information on time spent on your various pages

Heartbeat events are sent each minute from each page that the init event is implemented at, as long as the user does not navigate away from the page or the session is not considered timed out. It can provide information about time spent viewing each site by users.


Full Implementation

This is the list of all events that are supported by the Barion Pixel. You have to implement the following events on your site in every location applicable. The more accurately you implement these, the better service quality we can provide for you, especially in connection to your market and your users, as we will receive more and better data about them. Events may require parameters that must be included in the bp function call as a JS object. These contain additional information about an event, for example product IDs, categories, and the number of products purchased. If any properties are not required and are not applicable in your case, you can simply skip them. When the implementation is finished, all events must be checked by watching browser console messages throughout a test purchase.


Consent (grantConsent, rejectConsent)

  • User intent: Give or reject Barion Pixel consent
  • To be implemented at: Inside your own consent management software
  • Why do we need this: Participation of webshop clients is entirely consent based complying with the GDPR

Consent events determine which of the sent data can be used by us for marketing purposes. Two consent events can be used to control user consent. The "grantConsent" event has to be sent when the visitor accepts the cookie policy that expressly allows Barion to use data for marketing purposes. Sending this event must be handled by your own consent management implementation that you are responsible for as outlined in our terms. The "rejectConsent" event should be sent when the customer rejects the cookie policy that includes Barion Pixel functionality. It should be noted that rejecting Barion marketing consent does not mean that no data should be sent towards Barion, as Barion has a legitimate interest using this data for fraud management. Rejecting Barion consent however means that the data from that session will not be used for marketing purposes at all, despite receiving it. All consent events are sent by calling the Pixel's consent function as shown below. Usage of a fully compliant consent management platform (CMP) is strongly recommended by Barion. You can find our recommendation here


Consent event implementation example 

   
        bp('consent', 'grantConsent');
        bp('consent', 'rejectConsent');


Content View (contentView)

  • Firing event: Page load of item pages minimally, preferably on all pages that refers to a single item, offer or promotion
  • User intent: View the page that shows a single offer described exclusively
  • Why do we need this: Offer descriptions help us know more about your offers

This event should be fired when one of your users enters a page that refers to one of your items that can be bought, and describes it in general terms, with an offer to buy. This can be something like an offer page on an e-commerce website or a product page on a retail site. It is important to not confuse this with a full product detail page where the product itself is described in greater detail, but there is no information on price, shipping and other details that are relevant to you offer, like in the case of a product manual.

Content view event implementation examples:


Add to Cart (addToCart)

  • Firing event: Button click that results in a product to be selected for purchase
  • User intent: Select product for purchase
  • Why do we need this: Users demonstrate strong interest in your items by selecting them for purchase

The add to cart event is, as its name suggests, connected to a user "adding a product to their cart". Usually this means that a user decide to purchase a product or service, and has added this item to their cart. Even if your website does not use carts in the literal sense, there is a point in a user session where the given user decides that they intend to purchase the product. This exact intent is what we want to capture here, so the button click which best matches the point of this intent, such as one labeled 'Buy' or 'Reserve' should be the one to attach this event to.

Add to cart event implementation examples:


Initiate Checkout (initiateCheckout)

  • Firing event: Button click that starts the checkout process
  • User intent: Purchase the items in the cart
  • Why do we need this: Users usually are put off by adverts of an item they already purchased, but can be receptive to related products

Usually on a webshop, there is a checkout process that starts with clicking a button with items in your cart. This button click is the one that this event should be attached to. After this click, typically the user has to provide other data, such as a shipping address and method, and confirm the purchase (which should fire the initiate purchase event).

Initiate checkout event implementation examples:


Initiate Purchase (initiatePurchase)

  • Firing event: Button click that completes the checkout process
  • User intent: Pay for the items in the cart
  • Why do we need this: Users usually are put off by adverts of an item they already purchased, but can be receptive to related products

This event should be fired at the same time as the user is redirected to a payment solution's own website, for example when the user is sent to the Barion Smart Gateway for payment. It should also be fired if the user chose a non-payment checkout option, for example payment on receipt, but the transaction is considered complete. This should be the last confirmation of the checkout process, after which the sale is considered to have taken place. Ideally after pressing this button the user should reach either a 'payment pending' then a 'thank you' page, or simply the 'thank you' page.

Set User Properties (setUserProperties)

  • Firing event: Button click when user properties are available
  • User intent: Provide personal details
  • Why do we need this: Information about users helps us give more relevant offers to them

This event should be attached to any browser event that when fired, can access user information. We handle all user information in accordance with the GDPR and as such, all personally identifying information is hashed directly on the client side, in the JS code, before being forwarded to us, which makes it impossible to read it on our side. This makes it very important to fill out the properties provided below correctly, so that all PII falls in the correct fields that will be hashed before sending. The pages that this event can be inserted into are mostly sign up or sign in pages, newsletter subscription pages, and any other page where the user can provide information about themselves. This event can also be sent during the checkout process.

Purchase event implementation example:


Remove from Cart (removeFromCart)

  • Firing event: Button click that results in a product to be removed from the items selected for purchase
  • User intent: Deselect product for purchase
  • Why do we need this: Users demonstrate interest in carted products, and this can be refined if we know when products are deselected

The remove from cart event is very similar to the add to cart event, and is mainly required to refine our data on selected items by informing us when products are taken out from the cart or deselected from purchase. It can also mean that a purchase process that first made a user select an item is simply cancelled.

In this case, searches are sent asynchronously for partial search terms, which should not in themselves send an event. If you have a product selection page where items can be filtered, then the same can apply, the search string in this case can be the query that the settings make that can be read in your browser address bar in HTTP properties (eg. 'goats' in this: 'https://www.google.com/search?ei=A3rRXNHmJY-nrgSJs5HgDQ&q=goats').

Implementation FAQ

When do I have to send an event?
Every event description contains the trigger that may be a page load or a button click (Firing event at the event description).


What should I do if an event is undefinable in my web shop?
If event is not applicable to any user intent either explicitly or implicitly then you do not need to implement it.


Should visitors to a product page who are coming from external ads be tracked with a clickPromo event? (for example those that are provided by third party services such as Google Ads)
No, as the click event didn’t happen on your page, this event should not be tracked on your page.


When do I have to send the setUserProperties event?
Only when users first provide personal data about themselves or they modify them, you do not need to send this event at every sign in.


What event should be sent when my user registers and signs up for a newsletter during the registration process and is afterwards automatically logged in when the registration process is completed?
In that case, you should send a setUserProperties with the personal data, one signUp event for the registration, and another signUp event for the newsletter, and finally a third signUp event for the login.


What should I send in the variant property?
Before adding it to cart, you may specify the exact type of your product, such as size or color on the product page. You have to send the value that describes the variant, not the altered quality of the item. E.g. If you specify the size and color for a T-shirt, send ’Red|XXL’ instead of ’Size|Color’


Most events have the list and contentType property, what are they?
Both of them predefined values. contentType: Page/ Product/ Article/ Promotion/ Banner/ Misc, list: HomePage/ SearchPage/ ProductPage/ Recommendation/ ComparisonPage/ BasketPage/ Checkout/ Misc. ContentType describes the type of the visited page’s content. It is ‘product’ on product page/category selection pages. If it is an article then ‘Article’ or e.g. Black Friday promotion then ‘promotion’, general pages are ‘Page’ e.g. contact or about us pages. The list describes the functionality of the page, product page (ProductPage), basket page (BasketPage) or a page in the checkout process (Checkout) etc.


What is the step property?
First of all, consider the start point of the checkout process in your case. Usually, personal data and a delivery address are given after this point but before the actual purchase. This start point will be your initiateCheckout event where the value of step is 1. And then, split your checkout process up to the purchase into different steps, and fill this property with the position of the page in the checkout sequence.


What should I do if click on basket icon does not add item into basket in all case?
In that case, you have to manage different cases in different ways. The addToCart event should only be sent in the case when an item is actually added to the cart, otherwise you should not send this event.


I have empty cart button, how do I manage click on it by removeFromCart?
Send a removeFromCart event about each item that is in the cart.


What are name and ID properties in the signUp event?
These properties do not describe the user, the name identifies user intent, e.g. ’registration’, ’login’, ’newsletter’. The ID identifies the form or the checkbox. If there is no ID, then the same value can be entered as ID as the name.


Where can I find the Barion Pixel ID?
In your Barion wallet in the shop details menu.


If no results are returned to a search initiated by a customer, should a search event be sent?
Yes, in the same way as if the search results were not empty.


If quantity added to cart by the customer exceeds the acceptable quantity of items added to cart, which one should be sent in quantity property in addToCart event?
The quantity that was finally added to the cart. If no items are added to cart then you do not need to send an addToCart event.


When do I send a purchase event?
When a purchase is completed and finished by successful payment. If the user chooses cash as the payment method, then the purchase event should be sent when the user hits the ’Thank you’ page. If the user chooses online payment, then the purchase event should be sent when the user hits a ’Successful payment’ page.


What should I do if payment is unsuccessful?
In that case you must send a purchase event when the user hits an ’Unsuccessful payment’ page, however set the step property to -1. This special step value indicates that the payment has failed.


The item name on the product page is different from the same item in checkout process, what do I do?
The only thing that’s important is that all items should be named consistently in all events, meaning that the same item should have the same name in all cases.
