The following should be a valid request to create a charge and return the hosted URL:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.commerce.coinbase.com/charges/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$post = array(
"name" => "E currency exchange",
"description" => "Exchange for Whatever",
"local_price" => array(
'amount' => 'AMOUNT',
'currency' => 'USD'
),
"pricing_type" => "fixed_price",
"metadata" => array(
'customer_id' => 'customerID',
'name' => 'ANY NAME'
)
);
$post = json_encode($post);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_POST, 1);
$headers = array();
$headers[] = "Content-Type: application/json";
$headers[] = "X-Cc-Api-Key: YOUR-API-KEY";
$headers[] = "X-Cc-Version: 2018-03-22";
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
curl_close ($ch);
$response = json_decode($result);
return $response->data->hosted_url;

You can try this way. It's work for me
$curl = curl_init();
$postFilds=array(
'pricing_type'=>'no_price',
'metadata'=>array('customer_id'=>10)
);
$postFilds=urldecode(http_build_query($postFilds));
curl_setopt_array($curl,
array(
CURLOPT_URL => "https://api.commerce.coinbase.com/charges",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => $postFilds,
CURLOPT_HTTPHEADER => array(
"X-CC-Api-Key: APIKEY",
"X-CC-Version: 2018-03-22",
"content-type: multipart/form-data"
),
)
);
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);

Hello you can use php sdk for coinbase commerce.
https://github.com/coinbase/coinbase-commerce-php
composer require coinbase/coinbase-commerce
use CoinbaseCommerce\Resources\Charge;
use CoinbaseCommerce\ApiClient;
ApiClient::init('PUT_YOUR_API_KEY');
$chargeData = [
'name' => 'The Sovereign Individual',
'description' => 'Mastering the Transition to the Information Age',
'local_price' => [
'amount' => '100.00',
'currency' => 'USD'
],
'pricing_type' => 'fixed_price'
];
$chargeObj = Charge::create($chargeData);
var_dump($chargeObj);
var_dump($chargeObj->hosted_url);
