Lists sitemap pages for a given item type with optional pagination.
item_type only covers dynamic, repeater-generated items (Stores products, Blog posts,
Bookings services, etc. - see ItemType). It does NOT cover a site's static/main pages
(e.g. classic Editor "Home", "About", "Contact" pages) - those aren't represented by any
ItemType value and are never returned here, even for a fully published site. An empty or
partial pages result for a given itemType is not a signal that the site's static pages
are missing or unpublished.
This method is intended for headless sites, which fetch these entries to build and serve
their own sitemap.xml. Classic Editor/Studio sites don't need it - Wix generates and serves
their sitemap.xml for them. Note that the method does not detect or reject a site's editor
type; it reads the site's live Site Structure either way. So it is not a way to distinguish
headless from classic sites, and it is not the right tool for diagnosing a classic site's
auto-generated sitemap - inspect the sitemap XML served on that site's own domain instead.
Returns NOT_FOUND when the site is not indexable or is not published.
This method doesn't return any custom errors, but may return standard errors. Learn more about standard Wix errors.
