When capturing events, sometimes you may want to directly send identifying visitor information to Personalization such as the website visitor’s email address, social media username, or an identifier from another system (such as a subscriber ID).
Note for Drupal users
You can install and use the Drupal modules on your website to send identifying information to Personalization, including registration and login events and the corresponding email address of a website visitor.
Although you can use functions in the JavaScript API to capture these items, Personalization includes a special identity method which collects this information into a single array of values.
Note
To capture visitor identity with Google Tag Manager, see Capture visitor identity with Google Tag Manager.
To send a website visitor’s identity information directly to Personalization, use the following JavaScript code:
<script>
_tcaq.push(['captureIdentity', '<value>', '<identity-type>']);
</script>
Change the example based on your website’s needs by replacing the following variables:
<value> - The value you want to assign to a sub-parameter
<identity-type> - An information type that you can populate with a
visitor-specific value
Select from the following identity types for your use:
| Identity type | Description |
|---|---|
email |
Email address |
account |
Account ID, possibly an identifier from another tracking system |
facebook |
Facebook username |
twitter |
Twitter username |
name |
Name, including first, middle, last, or any combination of these |
| custom identifier | Customized visitor-specific information that you want
Personalization to treat as an identifier, such as
subscriber ID |
The captureIdentity method can send additional information as parameters,
like other Personalization Web capture methods. Send your parameters
based on the following example:
_tcaq.push(['captureIdentity', '<value-identity>', '<identity-type>', {'<parameter>':'<value-param>'}]);
Since the captureIdentity method supports sending only a single
identity sub-parameter, you can also add identity as a special type
parameter to your captureIdentity method, allowing you to send
one or more identity values to Personalization.
_tcaq.push(['captureIdentity', '<value-identity>', '<identity-type>', {'<parameter>':'<value-param>'}, {'identity':{'<value-identity-2>':'<identity-type-2>'}}]);
Note
If you are not sending any parameters with a capture event, but are
using identity as a parameter, be sure to include {} for the
empty list of regular parameters.
The following example sends a website visitor’s name and email address using a single JavaScript capture instruction:
_tcaq.push(['captureIdentity', '[email protected]', 'email', {}, {'identity':{'John':'name'}}]);
If you want to send website visitor identity information associated with a
website event (such as a registration event), you can use the identity
method as a parameter in the JavaScript event capture code. The following
example captures a page view with an event category of Technology along with
the website visitor’s email address:
_tcaq.push(['capture', 'Technology', {}, {'identity':{'[email protected]':'email'}}]);
