str
A unique ID of a web page view.
This should be kept the same for all user events triggered
from the same pageview. For example, an item detail page
view could trigger multiple events as the user is browsing
the page. The pageview_id property should be kept the
same for all these events so that they can be grouped
together properly.
When using the client side event reporting with JavaScript
pixel and Google Tag Manager, this value is filled in
automatically.
page_category
str
The most specific category associated with a category page.
To represent full path of category, use '>' sign to separate
different hierarchies. If '>' is part of the category name,
replace it with other character(s).
Category pages include special pages such as sales or
promotions. For instance, a special sale page may have the
category hierarchy:
"pageCategory" : "Sales > 2017 Black Friday Deals".
Required for view-category-page events. Other event
types should not set this field. Otherwise, an
INVALID_ARGUMENT error is returned.
uri
str
Complete URL (window.location.href) of the
user's current page.
When using the client side event reporting with
JavaScript pixel and Google Tag Manager, this
value is filled in automatically. Maximum length
5,000 characters.
referrer_uri
str
The referrer URL of the current page.
When using the client side event reporting with
JavaScript pixel and Google Tag Manager, this
value is filled in automatically. However, some
browser privacy restrictions may cause this
field to be empty.
