Cookie management

Tracking cookie 🍪

The JavaScript SDK creates a unique first-party cookie, which is used to measure the performance of advertising campaigns.

With each call to the Veasybl platform, the collected information (from the first-party cookie and the browsing context) is used to deliver relevant ads, while preserving the user experience.

In server-side implementations, the retailer’s site can allow Veasybl to access the browser's tracking cookie by acting as a cookie proxy.

When the user’s browser requests a page from the retailer's site, the retailer’s server reads the cookie value and then passes it to Veasybl via the API.

The first-party cookie created by the JavaScript library is named _vzbl_uid.

The lifetime of this cookie is configurable, ranging from 30 days to 12 months, depending on the retailer's preferences.

First-party cookies are created by the host domain – the domain the user is visiting. These types of cookies are generally considered good; they help provide a better user experience and keep the session open. This basically means the browser is able to remember key pieces of information, such as which items you add to shopping carts, your username and passwords, and language preferences.
