In WordPress 4.7 the filter
argument for any post endpoint was removed, The filter
argument allows the posts to be
filtered using WP_Query
public query vars. This plugin restores the filter
parameter for sites that were
previously using it.
Use the filter
parameter on any post endpoint such as /wp/v2/posts
or /wp/v2/pages
as an array of WP_Query
argument.
