mixpanel.add_group

Add a new group for this user.

Usage:

 mixpanel.add_group('company', 'mixpanel')
ArgumentTypeDescription
group_keyStringrequiredGroup key
group_idanyrequiredA valid Mixpanel property type
callbackFunctionoptionalIf provided, the callback will be called after tracking the event.

mixpanel.alias

The alias method creates an alias which Mixpanel will use to remap one id to another. Multiple aliases can point to the same identifier.

The following is a valid use of alias:

mixpanel.alias('new_id', 'existing_id');
// You can add multiple id aliases to the existing ID
mixpanel.alias('newer_id', 'existing_id');
 

Aliases can also be chained - the following is a valid example:

mixpanel.alias('new_id', 'existing_id');
// chain newer_id - new_id - existing_id
mixpanel.alias('newer_id', 'new_id');
 

Aliases cannot point to multiple identifiers - the following example will not work:

mixpanel.alias('new_id', 'existing_id');
// this is invalid as 'new_id' already points to 'existing_id'
mixpanel.alias('new_id', 'newer_id');
 

Notes:

If your project does not have ID Merge enabled, the best practice is to call alias once when a unique ID is first created for a user (e.g., when a user first registers for an account). Do not use alias multiple times for a single user without ID Merge enabled.

ArgumentTypeDescription
aliasStringrequiredA unique identifier that you want to use for this user in the future.
originalStringoptionalThe current identifier being used for this user.

mixpanel.clear_opt_in_out_tracking

ArgumentTypeDescription
optionsObjectoptionalA dictionary of config options to override
options.enable_persistence=truebooleanoptionalIf true, will re-enable sdk persistence
options.persistence_type=localStoragestringoptionalPersistence mechanism used - cookie or localStorage - falls back to cookie if localStorage is unavailable

options.secure_cookiebooleanoptionalWhether the opt-in cookie is set as secure or not (overrides value specified in this Mixpanel instance's config)

mixpanel.disable

Disable events on the Mixpanel object. If passed no arguments, this function disables tracking of any event. If passed an array of event names, those events will be disabled, but other events will continue to be tracked.

Note: this function does not stop other mixpanel functions from firing, such as register() or people.set().

ArgumentTypeDescription
eventsArrayoptionalAn array of event names to disable

mixpanel.get_config

returns the current config object for the library.


mixpanel.get_distinct_id

Returns the current distinct id of the user. This is either the id automatically generated by the library or the id that has been passed by a call to identify().

Notes:

get_distinct_id() can only be called after the Mixpanel library has finished loading. init() has a loaded function available to handle this automatically. For example:

// set distinct_id after the mixpanel library has loaded
mixpanel.init('YOUR PROJECT TOKEN', {
    loaded: function(mixpanel) {
        distinct_id = mixpanel.get_distinct_id();
    }
});

mixpanel.get_group

Look up reference to a Mixpanel group

Usage:

  mixpanel.get_group(group_key, group_id)
ArgumentTypeDescription
group_keyStringrequiredGroup key
group_idObjectrequiredA valid Mixpanel property type

Returns:

TypeDescription
ObjectA MixpanelGroup identifier

mixpanel.get_property

Returns the value of the super property named property_name. If no such property is set, get_property() will return the undefined value.

Notes:

get_property() can only be called after the Mixpanel library has finished loading. init() has a loaded function available to handle this automatically. For example:

// grab value for 'user_id' after the mixpanel library has loaded
mixpanel.init('YOUR PROJECT TOKEN', {
    loaded: function(mixpanel) {
        user_id = mixpanel.get_property('user_id');
    }
});
ArgumentTypeDescription
property_nameStringrequiredThe name of the super property you want to retrieve

mixpanel.has_opted_in_tracking

Returns:

TypeDescription
booleancurrent opt-out status

mixpanel.identify

Identify a user with a unique ID to track user activity across devices, tie a user to their events, and create a user profile. If you never call this method, unique visitors are tracked using a UUID generated the first time they visit the site.

Call identify when you know the identity of the current user, typically after login or signup. We recommend against using identify for anonymous visitors to your site.

Notes:

If your project has ID Merge enabled, the identify method will connect pre- and post-authentication events when appropriate.

If your project does not have ID Merge enabled, identify will change the user's local distinct_id to the unique ID you pass. Events tracked prior to authentication will not be connected to the same user identity. If ID Merge is disabled, alias can be used to connect pre- and post-registration events.

ArgumentTypeDescription
unique_idStringoptionalA string that uniquely identifies a user. If not provided, the distinct_id currently in the persistent store (cookie or localStorage) will be used.

mixpanel.init

This function initializes a new instance of the Mixpanel tracking object. All new instances are added to the main mixpanel object as sub properties (such as mixpanel.library_name) and also returned by this function. To define a second instance on the page, you would call:

mixpanel.init('new token', { your: 'config' }, 'library_name');
 

and use it like so:

mixpanel.library_name.track(...);
ArgumentTypeDescription

  // properties from it, then the old cookie is deleted
  // The upgrade config option only works in the initialization,
  // so make sure you set it when you create the library.
  upgrade: false
 
  // extra HTTP request headers to set for each API request, in
