Send MetaData via api about featured-image-by-url HOT 1 OPEN

I was able to update "image-by_url" meta data from WC api, the structure is something like this:

msg.payload= {
"name": $product_name,
"type": "simple",
"sku": $product_sku,
"regular_price": $product_price,
"manage_stock": true,
(...)
"meta_data": [{ "key": "_knawatfibu_url", "value": $image_url1 },
{ "key": "_knawatfibu_wcgallary", "value": [$image_url2, $image_url3, $image_url4]}]
};

"_knawatfibu_url" is the metadata key for featured image, and "_knawatfibu_wcgallary" must be an array of url strings.

from featured-image-by-url.
