Custom parameters
To identify visitors via custom parameters, follow these steps:
This is useful for websites with membership systems. When users log in, you can specify their identifier (ex: email, user_id, name) with our tracking code.
This helps you understand user behavior and identify any issues they encounter.
Add data-custom-parameters='{JSON_PARAMETERS_HERE}'
as shown in the example:
<script defer src="https://2.1lr.de/en/pixel/12345678910111213" data-custom-parameters='{"name": "John Doe", "email": "john@example.com"}'></script>
If this parameter is provided, you will see the icon next to the visitor on the Visitors page, indicating they have been identified with custom parameters.
