trest or trestclient for using put with nested fields

[JeroenL]

Hi,

I received this example from a WooCommerce plugin.

<?php

function sc_curl_post_req($url,$data){

  $curl = curl_init();

  curl_setopt($curl,CURLOPT_URL,$url);

  curl_setopt($curl,CURLOPT_POST,true);

  curl_setopt($curl,CURLOPT_POSTFIELDS,http_build_query($data));

  curl_setopt($curl,CURLOPT_RETURNTRANSFER,true);

  $result = curl_exec($curl);

  curl_close($curl);

  return json_decode($result,true);

}

$data = array(

  'order-id'=>1009,

  'tracking_url'=>'https://tracking-site.com/track/', // Tracking URL

  'tracking_num'=>'ABCXYZ134545', // Tracking Number

  'items'=>array( // Shipped items in current shipment

    array(

      'sku'=>'SK01', // Shipped item SKU

      'qty'=>1,    // Shipped item Qty

    ),

    array(

      'sku'=>'SK02',

      'qty'=>1,

    ),

  )

);

$url = 'https://your-site.com/wp-json/wxp-shipment-data/wxp-data/?key=44a298073f287782f48c6bd01bdcb5dd&actio...';

//action=update if action parameter passed in URL, it will create new shipment on every request

//if "action=update" removed from URL then it will return all existing shipment array and won't create any new shipment

$json = sc_curl_post_req($url,$data);

echo '<pre>'; print_r($json); echo '</pre>';

die;

Right now i have the needed fields shown above in a map component including the needed loop for the SKU's and the amount send.

How can i use either Trest or Trestclient to achieve what curl is doing in the example.

Thanks in advance
