BigCommerce API - Get Order Product By ID - php

Question

I am trying to get all Order Products of a given product_id within a collection of Orders using the following BigCommerce API call in PHP cURL:
Get an Order Product
$pid = $_POST['product_id'];
$filter = array("status_id"=>11);
$orders = Bigcommerce::getOrders($filter);
foreach($orders as $order) {
$oid = $order->id;
$URL = $store_url . "/api/v2/orders/$oid/products/$pid.json";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $URL);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0 );
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0 );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); //Get status code
$response = curl_exec($ch);
curl_close($ch);
$result = json_decode($response);
echo "OID: " . $oid . " PID: " . $pid . " var_dump: ";
print_r(var_dump($result) . "<br/>");
}
Output:
OID: 113948 PID: 4860 var_dump: array(1) { [0]=> object(stdClass)#3 (2) { ["status"]=> int(404) ["message"]=> string(37) "The requested resource was not found." } }
OID: 113949 PID: 4860 var_dump: array(1) { [0]=> object(stdClass)#220 (2) { ["status"]=> int(404) ["message"]=> string(37) "The requested resource was not found." } }
OID: 113954 PID: 4860 var_dump: array(1) { [0]=> object(stdClass)#3 (2) { ["status"]=> int(404) ["message"]=> string(37) "The requested resource was not found." } }
OID: 113957 PID: 4860 var_dump: array(1) { [0]=> object(stdClass)#220 (2) { ["status"]=> int(404) ["message"]=> string(37) "The requested resource was not found." } }
At first, I thought maybe the Orders did not contain the product_id I was looking for so I added this code to the top of the loop:
//Set $pid equal to the product_id of the first Order Product in the Order.
$pid = $order->products[0]->product_id;
New output:
OID: 113948 PID: 3703 var_dump: array(1) { [0]=> object(stdClass)#3 (2) { ["status"]=> int(404) ["message"]=> string(37) "The requested resource was not found." } }
OID: 113949 PID: 3627 var_dump: array(1) { [0]=> object(stdClass)#220 (2) { ["status"]=> int(404) ["message"]=> string(37) "The requested resource was not found." } }
OID: 113954 PID: 3816 var_dump: array(1) { [0]=> object(stdClass)#225 (2) { ["status"]=> int(404) ["message"]=> string(37) "The requested resource was not found." } }
OID: 113957 PID: 3646 var_dump: array(1) { [0]=> object(stdClass)#222 (2) { ["status"]=> int(404) ["message"]=> string(37) "The requested resource was not found." } }
Is what I'm trying to accomplish possible with the BigCommerce API, or do I have to iterate through all Order Products within the collection of Orders?
