用于发送付款的 Coinbase API 不起作用

Question

你好，我尝试制作一个 coinbase 钱包 api，它将用于自动发送付款作为 URL 从我的应用程序获取请求 仅使用 PHP，此代码中没有使用外部库 但是代码显示错误 404 即使我的 API 已启用并且我都尝试过 V2 V3

<?php
// Get the request parameters
$type = $_GET['type'];
$amount = $_GET['amount'];
$to = $_GET['to'];
$currency = $_GET['currency'];

// Check if the request is     valid
if ($type !== 'send' ||             !is_numeric($amount) ||     !filter_var($to,     FILTER_VALIDATE_EMAIL) ||     !in_array($currency, ['BTC',     'ETH', 'USDC'])) {
echo 'Invalid request';
exit;
}

// Create a Coinbase API     client
$client =     curl_init('https://api.coinbase.com/v3/');
curl_setopt($client,     CURLOPT_HTTPHEADER, [
    'Authorization: Bearer g3akagfskMRm0P5PE',
    'Content-Type: application/json',
    'X-Coinbase-API-Secret: o5FBZUPDvaJVnVXJmCKja-----+#WHHI',
]);

// Send the payment
$body = [
'amount' => $amount,
'currency' => $currency,
'recipient' => $to,
];
curl_setopt($client,     CURLOPT_POSTFIELDS,     json_encode($body));

// Get the response
$response = curl_exec($client);

// Check the response code
$code = curl_getinfo($client, CURLINFO_HTTP_CODE);
if ($code !== 200) {
echo 'Error: ' . $code;
exit;
}

// Decode the response body
$data = json_decode($response, true);

// Check if the payment was successful
if ($data['status'] === 'success') {
    echo 'Payment sent     successfully';
} else {
    echo 'Error: ' .     $data['error'];
}

// Close the connection
curl_close($client);
?>

试图自动发送付款但不起作用
