Problem using wp_remote_post to parse JSON response from external API - wordpress

Question

I am using wp_remote_post() to post products to a third party site. First I get these products via API from a site called Mercado Libre. But when I carry out the mass publication, the products are published without a name, without a price, and without respecting the parameters provided. They only have the name "Product".
function publish_products_in_woocommerce()
{
$respuesta = wp_remote_get('https://api.mercadolibre.com/sites/MLA/search?q=Motorola%20G6', array(
'headers' => array(
'Authorization' => 'Bearer APP_USR-2778915669536100-052221-0f3a39361bdcea9bc3de0df8ab619f66-370993848'
)
));
$respuesta = json_decode($respuesta['body'], true);
print_r($respuesta);
foreach ($respuesta['results'] as $value) {
$product_data = array(
'name' => $value['title'],
'status' => 'draft',
'type' => 'simple',
'regular_price' => $value['price'],
'description' => $value['title'],
'short_description' => $value['title'],
'categories' => [
[
'id' => $value['category_id'],
]
],
'images' => [
[
'src' => $value['thumbnail']
]
]
);
$woocommerce_api_ck = 'ck_b2a0f58d07590e8283302eca04fbc1b66a9ff653';
$woocommerce_api_cs = 'cs_b4d91662590be47416f663fc9f0d1c49f600e394';
$url = 'http://nuevo.labisbal.com.ar/wp-json/wc/v3/products';
wp_remote_post('http://nuevo.labisbal.com.ar/wp-json/wc/v3/products', array(
'headers' => array(
'Authorization ' => 'Basic ' . base64_encode($woocommerce_api_ck . ':' . $woocommerce_api_cs),
),
'body' => $ProductToWooCommerce = json_encode($product_data),
'method' => 'POST',
'timeout' => 145,
'blocking' => false,
'sslverify' => false,
'stream' => true,
'data_format' => 'json'
));
print_r($ProductToWooCommerce);
if (wp_remote_retrieve_response_message($respuesta) === 'Created') {
echo 'The product has been created';
}
}
}
publish_products_in_woocommerce();
?>
It's strange because when I display the json already converted (using json_encode) the data is displayed correctly... (using print_r)

I take a look at this and the issue is on how you sent the data to the API, when you use wp_remote_post you need to send the body as an array, and the method handles that information for you, so you don't need to convert it to JSON.
Below is a small test plugin that saves products using the WC REST API, the plugin adds a new endpoint to your site to trigger the scrapper https://yoursite.com/wp-json/wpapi/v1/fetch, I hope that helps.
Note: Please double check the code, is not fully tested.
