I have read other posts on this forum and none of which I read are solving my problem.
Whenever I do: http://www.example.com/wp-json/wp/v2/posts?filter[posts_per_page]=-1
Or even: http://www.example.com/wp-json/wp/v2/posts?filter[posts_per_page]=99
It still returns 10 posts. The same is happening when I try to get the Categories, or the Tags.
I have a request to pull ALL categories, tags, and posts from the REST API as a single list.
