JS Tag

This library allows mediarithmics customers to track user events on web sites and applications.

It loads a Javascript object in the page that can be used to send the proper events to the mediarithmics platform.

Please refer to the Web apps real time user tracking guide for details on how to use it.

When added to the page, the tag does 3 things :

• Adding the mediarithmics cookie

• If set up, start cookie-matching with partners

• Register events

Cookies used by the tag are considered ad-serving cookies. You must get the user consent before using it.

mics.init(token)

Init the script with your token. This call is mandatory and must be used before any mics.push() or mics.pushDefault().

Arguments

name	type	description
token	string	Your site token given by Mediarithmics.

Returns : nothing.Throws : an error if the token is invalid.

mics.init("MY_TOKEN");

mics.init({mode, site_token, domain_name})

Advanced way of initializing the TAG. Init the script with the mode of interaction, your site token and optionaly the custom domain name.

This call is mandatory and must be used before any mics.push() or mics.pushDefault().

Arguments

name	type	description
mode	string	The mode of interaction (in most cases it's a "VISIT"). In case of any doubt, please contact your mediarithmics account manager.
site_token	string	Your site token given by mediarithmics.
domain_name	object	(optional) The custom domain_name used to store the cookie on your domain, you should only use it when you use a custom DMP domain Ex: analytics.mydomain.com

Returns : nothing.Throws : an error if the token is invalid.

mics.init({
    mode: "VISIT", 
    site_token: "SITE TOKEN", 
    domain_name: "analytics.mydomain.com"
    });

mics.pushDefault()

Push the default event $page_view to mediarithmics..

Arguments : none. Returns : nothing. Throws : an error if mics.init has not been called.

mics.init("SITE TOKEN");
mics.pushDefault();

mics.push(event, properties)

Push a custom event with custom properties.

Arguments

name	type	description
event	string	the name of the event.
properties	object	the object containing the custom properties to push. Only string/boolean/number values are supported.

Returns : nothing. Throws : an error if mics.init has not been called.

mics.init("<SITE_TOKEN>");
mics.push("my_event", {
  my_prop1 : "value1",
  my_prop2 : 42
});

mics.addProperty(name, value)

Add a single property to be used for each mics push or pushDefault. You can call this method multiple times, the effects are cumulative.

See mics.addProperties(properties) to send multiple properties at once.

Arguments

name	type	description
name	string	the name of the property to add.
value	object	the value of the property to add.

Returns : nothing. Throws : nothing.

mics.addProperty("$user_account_id", <your unique user account id> );

mics.addProperties(properties)

Add properties to be used for each mics.push or mics.pushDefault. You can call this method multiple times, the effects are cumulative.

See mics.addProperty(name, value) to send only one property at once.

Arguments

name	type	description
properties	object	the object containing the custom properties to push. Only string/boolean/number values are supported.

Returns : nothing Throws : nothing

mics.addProperties({
  prop1 : "val1",
  prop2 : "val2"
});

It can be used to declare global properties to push :

mics.addProperties({
  prop1 : "val1",
  prop2 : "val2"
});

// will push prop1, prop2 and prop3
mics.push("my_event", {
  prop3 : "val3"
});

// will push prop1, prop2 and prop4
mics.push("my_event", {
  prop4 : "val4"
});

mics.addIdentifier(type,identifier)

Add an identifier to be used for each mics.push or mics.pushDefault. You can call this method multiple times with different identifier to add multiple identifiers. The effect of this method is idempotent: you can call it multiple times with the same input, the identifier will be registered only once.

Arguments

name	type	description
type	string	The type of identifier. Accepted values: "USER_ACCOUNT", "USER_EMAIL", and "USER_AGENT"
identifier	object	The object containing the identifier. Accepted values : - if type is "USER_ACCOUNT", identifier must be { $user_account_id: "account id"} or { $user_account_id: "account id", $compartment_token: "token" } - if type is "USER_EMAIL", identifier must be { $email_hash: "hash" } or { $email_hash: "hash", $email: "email" } - if type is "USER_AGENT", identifier must be { $user_agent_id: "user_agent_id" }. See UserAgentId. Agent type accepted are mobile advertising id, mobile vendor id, tv advertising id, and custom id.

You can pass an optional $expiration_ts property (Unix Epoch Time in milliseconds) with the identifier to specify an expiration

You should not add network device id here as they are managed from the UI. If the desired network device id is not available please contact support.

Returns : nothing (if arguments are invalid, call to this method will have no effect)

mics.addIdentifier(
    "USER_ACCOUNT", 
    { $user_account_id: "account id", $compartment_token: "token" }
);
mics.addIdentifier(
    "USER_ACCOUNT", 
    { $user_account_id: "account id", $compartment_token: "token", $expiration_ts: 1743580225000 }
);
mics.addIdentifier(
    "USER_EMAIL",
    { $email_hash: "hash", $email: "email" }
);
mics.addIdentifier(
    "USER_AGENT",
    { $user_agent_id: "dev:my-custom-registry:1234", $expiration_ts: 1743580225000 }
);

mics.onFinish(callback, timeout)

Register ONE callback to fire when the tag has finished sending events. Only the last registered callback will be fired.

Arguments

name	type	description
callback	function	function taking a boolean. True if everything was OK.
timeout	int	The timeout in milliseconds to start triggering events. Will call callback after event replies.

Returns : nothing.

mics.init("<SITE_TOKEN>");
mics.push("my_event", {
  my_prop1 : "value1",
  my_prop2 : 42
});
var start = new Date().getTime();
mics.onFinish(function(success) {
  var end = new Date().getTime();
  // end - start will be > 1000, but close to.
  console.log("done with success : ", success, " in ", end - start, "ms");
},1000);

mics.onStart(callback)

Returns : nothing

mics.init("<SITE_TOKEN>");
mics.push("my_event", {
  my_prop1 : "value1",
  my_prop2 : 42
});
var start = new Date().getTime();
mics.onStart(function() {
  var end = new Date().getTime();
  console.log("started in ", end - start, "ms");
});

mics.call(methodName, args)

Helper function to call a method without a snippet declaring it. Acts like a proxy function.

Arguments

name	type	description
methodName	string	the name of the method : (init, push, pushDefault, ...)
arguments	object...	the parameters of the method

Returns : underlying method result

mics.call("init", "<SITE_TOKEN>");
mics.call("push", "<EVENT_NAME>", {
  my_prop1 : "value1",
  my_prop2 : 42
});

mics.call("syncFeeds")

The syncFeeds method should be called after mics.init() to enable client-side feeds. It allows the tag to query mediarithmics servers to know if the user is in a segment synchronized with a client-side feed.

Arguments

name	type	description
methodName	string	syncFeeds
arguments	object...	none

Returns : Client-side feeds are now enabled

Session storage

For caching and integration purposes, the tag stores identifiers it retrieves in the browser session storage under the key mcssids.

The value is a stringified object with keys corresponding to the site token and the value an array of identifiers like the following :

{
  "<site_token>": [
    {
      "$type":"USER_ACCOUNT",
      "$compartment_token":"<compartment_token>"
      "$user_account_id":"account_1234"
      "$expiration_ts": 1234567890000 //ms
    },
    {
      "$type":"USER_EMAIL",
      "$email_hash":"oqlsdfhjiezkqdrufhiesqhfgr",
      "$expiration_ts": 1234567890000 //ms
    },
    {
      "$type":"USER_AGENT",
      "$user_agent_id":"<user_agent_id-non_authenticated_format>"
      "$expiration_ts": 1234567890000 //ms
    }
}

See user_agent_id for more details on $user_agent_id format

The session storage is specific to each browser tab and is erased when the tab is closed, making this storage temporary.
