Fetch everything the embedded widget needs to render: its style and the reviews to show. Called by the embed code when the page loads. Without feed_data (or with 0) you get the widget's settings only, inside data; with feed_data=1 you get a page of reviews from the widget's locations (newest first, limited to the review site in the widget's options), the average rating and the settings, with data as the review array.

Prerequisites: a bearer token, and the widget's unique_id (from the embed code or List review widgets). The widget's location needs an active widget add-on, otherwise 400.

Authentication: Partner or Account token. Any valid token works; the widget doesn't have to be in your account tree, because it's shown on public pages.

Rate limit: none.
