List every site across your locations that has no review URL or no landing page URL yet. This is a report; it changes nothing. Use this after setting up new locations to see what still needs a URL, or as a regular check that collection is running everywhere it should. It covers every location you can reach; narrow it with account_id or review_site_id. Returns the sites missing either URL, one page at a time. Fill them in with Set a site's URLs and credentials.

Prerequisites: a bearer token.

Authentication: Partner or Account token. Only locations inside your own account tree are listed (a Partner token sees every location under the partner, an Account token only its own account's locations); an account_id outside your tree returns an empty page.

Rate limit: none.
