Optional. Indicates if the request is made directly from the end user
in which case the user_agent and ip_address fields can be populated
from the HTTP request. This should not be set when using the javascript
pixel. This flag should be set only if the API request is made directly
from the end user such as a mobile app (and not if a gateway or a server is
processing and pushing the user events).
Optional. IP address of the user. This could be either IPv4 (e.g. 104.133.9.80) or
IPv6 (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334). This should not be
set when using the javascript pixel or if direct_user_request is set.
Used to extract location information for personalization.
Required. A unique identifier for tracking visitors with a length limit of
128 bytes.
For example, this could be implemented with a http cookie, which should be
able to uniquely identify a visitor on a single device. This unique
identifier should not change if the visitor log in/out of the website.
Maximum length 128 bytes. Cannot be empty.
