If I rename or remove any parameter, then authentication is failed. So I hope that, I'm passing some wrong value. But I couldn't find out which one is..
I tried to change almost every field values which I'm passing, but every time getting same error
ERROR 101 - Request parameters are invalid or missing

Answer 1

Finally I found sample code (php) from Cyber Source, we just have to configure as per the credential. Here is the link
Source Code
You have to define you Secret key in security.php file
define ('SECRET_KEY', '7f15d699ff14461b9a84*****');
And,
access_key and profile_id in signeddatafields.php file
<input type="hidden" name="access_key" value="5e00e27842d73******">
<input type="hidden" name="profile_id" value="43C533AC-****-****-****-*********">
That's it.

Answer 2

I only did the SOAP as well, but after a look at their rest v1 example, it looks like the api key and secret key are passed to create a paytoken in the Apiclient. An authorization payment should be something like this(after u install the sdk):
<?php
use \CyberSource\Authorizations as Authorizations;
use \CyberSource\Configuration as Configuration;
class CyberSource {
private $config;
function __construct($apiKey, $secretKey) {
// pass apikey and secretkey to configuration
$this->config = new Configuration($apiKey, $secretKey);
}
private function runAuth($this->config) {
$api = new Authorizations($this->config);
$jsonPayload = // ur json request payload
try{
// pass the request json payload object
$response = $api->createAuthorization($jsonPayload);
} catch (\E $e) {
//throw error here
}
}
}
if you have to use v2 then u need to read this pdf there are several things you need to add to the header for account authentication.
