WooCommerce REST API - how to get product resized images url? - woocommerce-rest-api

Question

all images in wordpress will auto resize and save in uploads folder like this:
sample_product_image-100x100.png
sample_product_image-150x150.png
sample_product_image-180x113.png
sample_product_image-300x189.png
...
sample_product_image-555x349.png
sample_product_image-600x378.png
sample_product_image.png (original large file)
for faster loading I need smaller size of product image in rest api like this one:
sample_product_image-300x189.png
but woocommerce rest api just send me original largest file (sample_product_image.png):
"images": [
{
"id": 7291,
"date_created": "2018-06-12T03:17:03",
"date_created_gmt": "2018-06-11T13:47:03",
"date_modified": "2018-06-12T03:17:03",
"date_modified_gmt": "2018-06-11T13:47:03",
"src": "http://example.com/wp-content/uploads/2018/06/sample_product_image.png",
"name": "sample_product_image",
"alt": "",
"position": 0
},
how can I get smaller image urls in wc rest api?
btw I found this plugin for wordpress rest api that is not working for woocommerce.

found a solution here.
Just need to add this filter to your theme's function.php
function prepare_product_images($response, $post, $request) {
global $_wp_additional_image_sizes;
if (empty($response->data)) {
return $response;
}
foreach ($response->data['images'] as $key => $image) {
$image_urls = [];
foreach ($_wp_additional_image_sizes as $size => $value) {
$image_info = wp_get_attachment_image_src($image['id'], $size);
$response->data['images'][$key][$size] = $image_info[0];
}
}
return $response;
}
add_filter("woocommerce_rest_prepare_product_object", "prepare_product_images", 10, 3);
Also if you need only 1 special size you can remove second foreach and manually initialize $size to 'thumbnail' , 'medium' , 'medium_large' or 'large'
