I keep on getting HTTP/1.1 400 Invalid Request Connection: close Content-Length: 28 content-type: text/plain; charset=utf-8 x-served-by: cache-lon420138 broken content-length header when calling from PHP the cURL, and I do not know why, it is highly annoying,
Here is my Javascript call:
// Call your server to finalize the transaction
onApprove: function(data, actions) {
console.log('Order ID:', data.orderID);
console.log('Data:', data);
return fetch('../captureOrder.php?orderID=' + data.orderID, {
method: 'post'
})
.then(response => {
if (!response.ok) {
return response.text().then(text => {
throw new Error('Failed to capture order: ' + text);
});
}
return response.json();
})
.then(orderData => {
if (orderData.error || orderData.http_status >= 400) {
let errorMessage = orderData.error_description || "An unknown error occurred.";
console.error('Error:', orderData.error, errorMessage);
alert('Error: ' + errorMessage);
} else if (orderData.success && orderData.data && orderData.data.status === 'COMPLETED') {
console.log('Capture result', orderData.data);
alert('Transaction ' + orderData.data.id + ': ' + orderData.data.status + '\n\nSee console for all available details');
} else {
console.error('Transaction was not completed:', orderData);
alert('Transaction could not be completed. Please try again.');
}
})
.catch(error => {
console.error('Transaction failed:', error.message);
alert('There was a problem with your payment. Please try again. ' + error.message);
});
}
Here is my PHP script:
<?php
ini_set('display_errors', 1);

$orderID = isset($_GET['orderID']) ? $_GET['orderID'] : null;

http_response_code(400);
echo json_encode(['error' => 'Missing order ID']);
exit;
}
$accessToken = generateAccessToken();
if (empty($accessToken)) {
http_response_code(500);
echo json_encode(['error' => 'Failed to obtain access token']);
exit;
}
$url = "https://api-m.paypal.com/v2/checkout/orders/{$orderID}/capture";
$ch = curl_init($url);
$requestId = uniqid();
$uniqueOrderID = "YourUniqueOrderID"; // This should ideally come from your order system.
$paypalClientMetadataId = time() . "-" . $uniqueOrderID;
// Setting headers including Prefer and PayPal-Client-Metadata-Id
$headers = [
"Content-Type: application/json",
"Authorization: Bearer $accessToken",

];
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

curl_setopt($ch, CURLOPT_VERBOSE, true); // To get detailed info about the request/response
$response = curl_exec($ch);
/*echo $response;
exit;*/
$curlError = curl_error($ch);
if (!$response) {
curl_close($ch);
http_response_code(500);
echo json_encode(['error' => 'Failed to capture order.', 'curlError' => $curlError]);
exit;
}
list($headers, $body) = explode("\r\n\r\n", $response, 2);
curl_close($ch);
$responseData = json_decode($body, true);
if (!$responseData) {
http_response_code(500);
echo json_encode(['error' => 'Failed to capture order. No response data from PayPal.']);
exit;
