Internal Server Error on VPP API

[virsymcoin]

Hello Visa developer team!

I'm going to use VPP API on my site.

I have encrypted payload body and send request.

But I'm getting internal server error.

Below is php script to call api and send request.

Please Help Me.

Best Regards.

$pub_key = openssl_pkey_get_public(file_get_contents(APPPATH . 'third_party/visa/server_cert.pem'));
$keyData = openssl_pkey_get_details($pub_key);
$publicKey = $keyData['key'];
$ivlen = openssl_cipher_iv_length($cipher="AES-128-GCM");
$iv = openssl_random_pseudo_bytes($ivlen);
$tag = "";
$encrypted = openssl_encrypt ($requestBodyString, $cipher, $publicKey, $options=OPENSSL_RAW_DATA, $iv,$tag);
$hmac = hash_hmac('sha256', $encrypted, $publicKey, $as_binary=true);
$encrypted = base64_encode($encrypted);
$curl = curl_init ();
$headers = (array("Accept: application/json", "Authorization: ".base64_encode("user_id:user_password")));
$absUrl = "https://sandbox.api.visa.com/acs/v1/payments/authorizations";
array_push($headers, "Content-Type: application/json");
$this->timeout = 80;
$this->connectTimeout = 30;
$method = "post";

$userId = "--user_id--";
$password = "user password";

$authString = $userId.":".$password;$authStringBytes = utf8_encode($authString);
$authloginString = base64_encode($authStringBytes);
$authHeader= "Authorization:Basic ".$authloginString;
$header = (array("Accept: application/json", "Content-Type: application/json", $authHeader));
$ch = curl_init();
$opts [CURLOPT_POST] = 1;
$opts [CURLOPT_POSTFIELDS] = $encrypted;
$opts [CURLOPT_URL] = $absUrl;
$opts [CURLOPT_RETURNTRANSFER] = true;
$opts [CURLOPT_CONNECTTIMEOUT] = $this->connectTimeout;
$opts [CURLOPT_TIMEOUT] = $this->timeout;
$opts [CURLOPT_HTTPHEADER] = $headers;
$opts [CURLOPT_HEADER] = 1;
curl_setopt($curl, CURLOPT_FAILONERROR, true);
curl_setopt_array ( $curl, $opts );

$response = curl_exec ( $curl );
$statusCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);
curl_close($curl);

@virsymcoin  - can you also share the correlation ID from the error? We are also trying to view it in our logs to see what happened.
