["analytics", "affiliates", "personalization"]

`utag.gdpr.getCategoryLanguage()`

Returns an Object with the category name and description in the active language. The language of the category is the language returned by the getLanguage() function.

For more information on categories, see Manage consent preferences.

utag.gdpr.getCategoryLanguage(category)

Parameter	Type	Description

`utag.gdpr.getConsentState()`

Returns one of two data types, as follows:

A numeric value indicating the consent state (full, declined, or no consent).
For partial consent, an Array of Objects specifying consent by category.

When full, declined, or no consent is given, one of the following consent state values is returned:

Consent State	Consent Value	Description
Full	`1`	Full consent was given (`consent:true` on the cookie).
Decline	`-1`	Consent was declined (`consent:false` on the cookie).
None Given	`0`	No consent is given (no cookie present).

When partial consent is given, an Array of Objects is returned. Each Object represents a consent category. For each Object in the Array, the "ct" key represents the consent value (1/0), and the "name" key specifies the consent category.

utag.gdpr.getConsentState()

The following example shows an Array of Objects returned for partial consent:

[{"ct":"1","name":"analytics"},
{"ct":"0","name":"affiliates"},
{"ct":"0","name":"display_ads"},
{"ct":"0","name":"search"},
{"ct":"0","name":"email"},
{"ct":"0","name":"personalization"},
{"ct":"0","name":"social"},
{"ct":"0","name":"big_data"},
{"ct":"0","name":"misc"},
{"ct":"0","name":"cookiematch"},
{"ct":"0","name":"cdp"},
{"ct":"0","name":"mobile"},
{"ct":"0","name":"engagement"},
{"ct":"0","name":"monitoring"},
{"ct":"0","name":"crm"}]

`utag.gdpr.getCookieValues()`

Instead of using this function directly, it is recommended that you use a function such as utag.gdpr.getConsentState(), which calls the getCookieValues() function to read the cookie.

Returns an Object representing the consent cookie as key-value pairs. This function uses the default cookie namespace (CONSENTMGR) or the value provided in window.utag_cfg_ovrd.cmcookiens. The reverse function (writing into the cookie) is utag.gdpr.setCookie().

utag.gdpr.getCookieValues()

The following example shows the Array returned by utag.gdpr.getCookieValues() for partial consent:

{
    "c1":"1",
    "c2":"0",
    "c3":"0",
    "c4":"0",
    "c5":"0",
    "c6":"0",
    "c7":"0",
    "c8":"0",
    "C9":"0",
    "c10":"0",
    "c11":"0",
    "c12":"0",
    "c13":"0",
    "c14":"0",
    "c15":"0",
    "ts":"1586965568213",
    "consent":"true"
}

The following example shows the Array returned by utag.gdpr.getCookieValues() for full consent:

utag.gdpr.getCategories(true)

{"consent":"true","ts":"1587026030058"}

`utag.gdpr.getLanguage()`

Returns a String with the language used for displaying the consent manager content. Ordered by precedence of the language as set up in the data layer, the language from the browser, or the default language.

utag.gdpr.getLanguage()

The following example shows the String returned when the language is English (United Kingdom):

"en-gb"

`utag.gdpr.getSelectedCategories()`

Returns an Array that contains the categories selected by the customer.

utag.gdpr.getSelectedCategories()

The following example shows an Array returned by utag.gdpr.getSelectedCategories():

["analytics", "personalization"]

`utag.gdpr.setAllCategories()`

Sets all categories to the same consent state of either consented or declined, and (optionally) calls the Collect API to track the consent.

utag.gdpr.setAllCategories(state, noCollect)

Parameter	Type	Description
`state`	`Boolean`	Set to `true` to allow consent to all categories, set to `false` to decline consent.
`noCollect`	`Boolean`	(Optional) Set to `true` to not call the Collect API to track the consent.

The following example specifies consent for all categories, with no call to the Collect API:

utag.gdpr.setAllCategories(true,true)

The following example declines consent for all categories, and calls the Collect API to track the consent:

utag.gdpr.setAllCategories(false)

`utag.gdpr.setConsentValue()`

Sets the consent cookie value to enabled or disabled. The function also updates the timestamp of consent, and generates a tracking call to the Collect API, and replays tags that are kept in the queue utag.gdpr.queue.

utag.gdpr.setConsentValue() doesn’t change the consent value of individual categories. The consent value needs to be disabled via the relevant API call (setPreferencesFromList() or setPreferencesValues()).

utag.gdpr.setConsentValue(_response)

Parameter	Type	Description
`_response`	`Boolean`	Set to `true` enable consent, or `false` to disable consent.

The following example sets the cookie to the value "consent:true" and updates the timestamp:

utag.gdpr.setConsentValue(true)

The following example sets the cookie to the value "consent:false" and updates the timestamp:

utag.gdpr.setConsentValue(0)

`utag.gdpr.setCookie()`

We do not recommend calling this function directly.

Internal function that writes directly to the cookie Object. It uses an Object to represent the consent state, the timestamp, and the various categories for partial consent. It automatically uses the correct cookie name and expiry period.

utag.gdpr.setCookie(onlyEnabledCats)

Parameter	Type	Description
`cookieData`	`Object`	List of key-values representing the data stored in the consent cookie.

Example:

var object = {"c6":"1","c1":"0","c2":"0","ts":1587133550264,"consent":"false","c3":"0","c4":"0","c5":"0","c7":"0","c8":"0","c9":"0","c10":"0","c11":"0","c12":"0","c13":"0","c14":"0","c15":"0"}

utag.gdpr.setCookie(object)

`utag.gdpr.setCookieValue()`

Sets an individual value in the consent cookie.

This function is used by other higher level functions such as setConsentValue(). Use this method cautiously and only if higher level functions do not fulfill the initial needs.

utag.gdpr.setCookieValue(key, value);

Parameter	Type	Description
`key`	`String`	Key used in the cookie that is set to either `consent`, `ts` or any of the categories specified by the `c` value representation, such as `c1` for Analytics or `c2` for Affiliates.
`value`	`String`	The value to set in the cookie key.

The following example sets the consent cookie to "consent:false":

utag.gdpr.setCookieValue("consent", false);

The following example sets consent cookie to "c1:0":

utag.gdpr.setCookieValue("c1", 0);

`utag.gdpr.setPreferencesFromList()`

Sets the consent state to allowed for the list of categories passed in the parameter. The consent state of the categories that are not in the list is set to declined. This is used for partial consent. This function relies on the setPreferencesValues() function and provides the reverse functionality of getSelectedCategories().

utag.gdpr.setPreferencesFromList(list)

Parameter	Type	Description
`List`	`Array`	`Array` of valid categories.

The following example sets the consent state for the "analytics" category in the consent cookie:

utag.gdpr.setPreferencesFromList(["analytics"])

`utag.gdpr.setPreferencesValues()`

Sets the cookie preferences values from an Object of categories and their consent state. This function is mainly called by the setPreferencesFromList() function. This function replays the tags that are kept in the queue utag.gdpr.queue.

utag.gdpr.setPreferencesValues(state, noCollect)

Parameter	Type	Description
`state`	`Object`	Key-value pairs in the format `category:consentState`.
`noCollect`	`Boolean`	(Optional) Set to `true` to not call the Collect API to track the consent.

The following example sets the cookie value for the "analytics", "affiliates", and "personalization" categories:

Var cats = {"analytics":"1","affiliates":"0","personalization":"0"}
utag.gdpr.setPreferencesValues(cats)

`utag.gdpr.showConsentPreferences()`

Displays the consent preferences pop-up. This function injects the CSS, the HTML and the Javascript defined in the customizations in the page. It is called by the explicit consent javascript listener or from any point in the page where the user wants to modify their preferences.

utag.gdpr.showConsentPreferences(_lang)

Parameter	Type	Description
`_lang`	`String`	(Optional) Language specified in ISO format, such as `en` or `en-gb`.

The following example displays consent in the default language or the language set up in the data layer:

utag.gdpr.showConsentPreferences()

The following example displays consent in French:

utag.gdpr.showConsentPreferences("fr-fr")

`utag.gdpr.showDoNotSellBanner()`

Displays the CCPA banner. By default, this function is called when the enforcement rule evaluates to true.

utag.gdpr.showDoNotSellBanner(_lang)

Parameter	Type	Description
`_lang`	`String`	(Optional) Language specified in ISO format, such as `en` or `en-gb`.

The following example displays the CCPA banner in the default language or the language set up in the data layer:
