Required parameter missing or invalid while create draft orders REST API in shopify APP

[vinodk]

I am working on public custom shopify app where i am creating draft order with custom price of items. I am facing the issue "Required parameter missing or invalid", below is my REST API Curl code.

$postorderarray = [
"draft_order" => [
"line_items" => [
[
"title" => "Custom Tee",
"price" => "20.00",
"quantity" => 2
]
],
"customer" => [
"id" => 6453791457508
],
"use_customer_default_address" => true
]
];

$url = 'https://shopurl/admin/api/2022-10/draft_orders.json;
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_MAXREDIRS, 3);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($curl, CURLOPT_TIMEOUT, 30);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, POST);

$headers[] = "X-Shopify-Access-Token: " . $access_token;
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
if (is_array($postorderarray)) $postorderarray = http_build_query($postorderarray);
curl_setopt($curl, CURLOPT_POSTFIELDS, $postorderarray);
$response = curl_exec($curl);
$error = curl_errno($curl);
$error_msg = curl_error($curl);
curl_close($curl);

Hey @vinodk, your code looks correct, very odd. One thing that could cause this would be an invalid customer ID, although the error message would appear differently. Can you share an X-Request-ID from the Shopify response to an example call where you saw the "Required parameter missing or invalid" error message. Happy to dig into this with you.
