How can I get a list of posts for a category with WP-API?

Question

Should be easy, but didnt find it in the WP-API docs.

Answer 1

This question is a duplicate from this other question here from the forum

http://example.com/wp-json/wp/v2/posts?categories=20,30

The above will return posts from category 20 OR category 30

I've tested with custom post types and it also works perfectly

This code is working for me

Add to your function.php

function rest_filter_by_custom_taxonomy( $args, $request ) {

if ( isset($request['category_slug']) )
{
    $category_slug = sanitize_text_field($request['category_slug']);
    $args['tax_query'] = [
        [
            'taxonomy' => 'category',
            'field'    => 'slug',
            'terms'    => $category_slug,
        ]
    ];
}

return $args;

 }
 add_filter('rest_post_query', 'rest_filter_by_custom_taxonomy', 10, 3);

EX: /wp-json/wp/v2/posts?category_slug=news
