It allows you to set or remove cookies via data layer pushes. See the recipe description for details of the information to include in the data layer push.

Set a cookie by pushing an event to the Data Layer with the following syntax:

dataLayer.push({
 'event': 'setCookie',
 'attributes': {
 'cookieName': 'my_cookie_name',
 'cookieValue': 'my_cookie_value',
 'cookieDomain': 'www.myhostname.com',
 'cookiePath': '/',
 'cookieExpires': 1 // Number of days - provide a fraction for periods less than 24 hours
 }
});

dataLayer.push({

'event': 'setCookie',

'attributes': {

'cookieName': 'my_cookie_name',

'cookieValue': 'my_cookie_value',

'cookieDomain': 'www.myhostname.com',

'cookiePath': '/',

'cookieExpires': 1 // Number of days - provide a fraction for periods less than 24 hours

}

});

To remove the same cookie, use the following syntax:

dataLayer.push({
 'event': 'removeCookie',
 'attributes': {
 'cookieName': 'my_cookie_name',
 'cookieDomain': 'www.myhostname.com',
 'cookiePath': '/',
 }
});

dataLayer.push({

'event': 'removeCookie',

'attributes': {

'cookieName': 'my_cookie_name',

'cookieDomain': 'www.myhostname.com',

'cookiePath': '/',

}

});
