The hosted payment pages can use the Google Analytics Measurement Protocol to send information on customer progress through the payment pages. You will need to provide your tracker ID, the customers Client ID, and details of the domain you want to record the events under.

Field	Description	Notes
tid	Tracker ID	Your Google Analytics tracker ID
cid	Client ID	The customer's client ID
dh	Your hostname	No protocol (such as http: etc), just the domain (e.g. www.site.com)
dp	Document path	This will be used as a prefix to the path sent at each stage. It must start with '/'
ds	Data source	Optional. If not set, then 'web' will be used.
cn	Campaign name	Optional fields to allow you to specify any required campaign tracking values.
cs	Campaign source	Optional fields to allow you to specify any required campaign tracking values.
cm	Campaign medium	Optional fields to allow you to specify any required campaign tracking values.
ck	Campaign keyword	Optional fields to allow you to specify any required campaign tracking values.
cc	Campaign content	Optional fields to allow you to specify any required campaign tracking values.
ci	Campaign ID	Optional fields to allow you to specify any required campaign tracking values.
gclid	AdWords ID
dclid	Display Ads ID

The URL sent for each payment stage is constructed by adding the following to the value in ’dp’

URL	Description
/<<company_name_lower_case>>/data_entry.html	Initial Data Entry
/<<company_name_lower_case>>/service_out.html	Redirect to service provider
/<<company_name_lower_case>>/service_back.html	Return from service provider
/<<company_name_lower_case>>/mpi_check.html	3D-Secure Enrolment Check
/<<company_name_lower_case>>/acs_out.html	Redirect to card issuer (3D Secure)
/<<company_name_lower_case>>/acs_back.html	Return from card issuer (3D Secure)
/<<company_name_lower_case>>/card_auth.html	Card authorisation request
/<<company_name_lower_case>>/authorised.html	Transaction authorised
/<<company_name_lower_case>>/declined.html	Transaction declined
/<<company_name_lower_case>>/cancelled.html	Transaction cancelled

If you have set ‘ga_dp’ to a value such as ‘/payments’ then the URLs sent to the analytics system would be ‘/payments/<<company_name_lower_case>>/data_entry.html’, ‘/payments/<<company_name_lower_case>>/mpi_check.html’ and so on.

    "cartid": "1234",
    "test": "1",

  "ga": {

		"ck": "xxx",
		"cc": "xxx",
		"ci": "xxx",

		"dclid": "xxx"
	}
}

Obtaining the client ID

You will need to get the client ID from the Google Analytics code you are operating on your site prior to sending the transaction request. If you are using the analytics.js method, then you can use the following code on your page to retrieve the client ID:

ga(function(tracker) {  
  var clientId = tracker.get('clientId');  
});

See https://developers.google.com/analytics/devguides/collection/analyticsjs/domains#getClientId for more details.
