Cookie Functions

Reference guide for cookie functions provided by Tealium for JavaScript.

utag.loader.SC()

This function sets and deletes multi-value cookies inside the namespace utag_. It is commonly used to set utag_main subcookies to avoid adding extra cookies.

To minimize the number of cookies on your domain, we recommended setting a multi-value cookie object. A multi-value cookie stores several values, as key-value pairs, within one cookie namespace. The function is commonly used to set utag_main

This is the same function used by the Persist Data Value extension.

The following format demonstrates how to set a cookie by identifying the cookie’s namespace, name, value, optional expiration time, and optional flag for specifying additional functionality:

utag.loader.SC(namespace, {"name": "value;exp-expiry"}, flag);
Parameter Type Description Example
namespace String The namespace of the cookie, which must start with utag_. "utag_multi"
name:value Object An object of key-value pairs representing a multi-value cookie. {"uid": "012345689", "aff": "SiteAff1;exp-7d"}
expiry String (Optional) The expiration of the cookie, which must start with exp-. exp-12h
flag String (Optional) A flag to delete one or more cookies. "d"

Expiry Options
The following cookie expiry options are available:

Expiry unit Description Example
#d Expiry time in days (default unit, if none provided) exp-7d or exp-7 (7 days)
#h Expiry time in hours "exp-8h" (8 hours)
#u Expiry time at Unix timestamp "exp-1549271521u" (Midnight (GMT) on Dec 22, 2022)
session Expiry time at end of session (default session timeout: 30 minutes) "exp-session"

Timestamp-based expiration, such as "exp-1549271521u", has a trailing u indicates Unix timestamp. Do not confuse it with the value set in the cookie itself such as "exp-1549271521"

If no expiry option is set, then the default behavior is based on the version of utag.js:

  • 4.27+ - default expiry is 1 year after the creation of the cookie.
  • 4.26 or older - default expiry is the year 2099.

Set a Cookie
To set a multi-value cookie, pass an object of key-value pairs of to the value parameter.

The following example creates a multi-value cookie named utag_multi:

utag.loader.SC("utag_multi", {
    "uid"      : "012345689",      // default expiry
    "test_seg" : "groupA;exp-12h", // 12 hour expiry
    "aff"      : "SiteAff1;exp-7d" // 7 day expiry
});

Delete a Cookie
To delete one or more cookie values, use the optional flag parameter.

Delete one or more values from a multi-value cookie. Each key-value pair specified is deleted:

utag.loader.SC("utag_multicookie", {"test_seg":"", "aff":""}, "d");

Delete all values from a multi-value cookie:

utag.loader.SC("utag_multicookie", {}, "da");
