In this post, I am making WordPress rest api, with I am getting woocommerce product by category slug.Here is the code snippet and you need to add this into your theme’s functions.php file:

 add_action( 'rest_api_init', function () {
 register_rest_route( 'productfiltercat/v1', '/product/category/(?P<slug>[^/]+)', array(
    'methods' => 'GET',
    'callback' => 'therich_func',
  ) );
} );
function therich_func( $data ) {

  $p = wc_get_products(array('status' => 'publish', 'category' => $data['slug']));
     $products = array();

     foreach ($p as $product) {

    $products[] = $product->get_data();

     }

     return new WP_REST_Response($products, 200);
}

Here is my Rest API path:

http://localhost/wordpress/wp-json/productfiltercat/v1/product/category/category-1
