Data Layer

How it works

To set global data layer values once instead of setting them in every tracking call, use the AddToDataLayer() method. Data layer values added with this method are included in every tracked event, including lifecycle events. Set the expiry parameter to the length of time to persist the value.

Usage

To set data layer values, call AddToDataLayer() with a data dictionary and an expiration parameter.

To learn more, see AddToDataLayer() and Expiry.

tealium.AddToDataLayer(new Dictionary<string, object>(1) {
    {"user_language", "en-EN"}
  },
  Expiry.Forever
);

To get a data layer value, call GetFromDataLayer() with the name of the value to retrieve.

string myString = (string)tealium.GetFromDataLayer("user_language");
