pageCategories property
The categories 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: "pageCategories" : ["Sales > 2017 Black Friday Deals"].
Required for category-page-view events. At least one of search_query or
page_categories is required for search events. Other event types should
not set this field. Otherwise, an INVALID_ARGUMENT error is returned.
Implementation
core.List<core.String>? pageCategories;
