It's a basic configuration of the SDK

require_once __DIR__ . '/vendor/autoload.php';
use NpsSDK\Configuration;
use NpsSDK\Constants;
Configuration::environment(Constants::STAGING_ENV);
Configuration::secretKey(“yourSecretKeyHere”);

Here is an simple example request:

require_once __DIR__ . '/vendor/autoload.php';

use NpsSDK\Sdk;
use NpsSDK\ApiException;
use NpsSDK\Configuration;
use NpsSDK\Constants;

Configuration::environment(Constants::SANDBOX_ENV);
Configuration::secretKey("YourKeyhere");

$sdk = new Sdk();

$params = array(
    'psp_Version'          => '2.2',
    'psp_MerchantId'       => 'psp_test',
    'psp_TxSource'         => 'WEB',
    'psp_MerchTxRef'       => 'ORDER56666-3',
    'psp_MerchOrderId'     => 'ORDER56666',
    'psp_Amount'           => '1000',
    'psp_NumPayments'      => '1',
    'psp_Currency'         => '032', 
    'psp_Country'          => 'ARG', 
    'psp_Product'          => '14',
    'psp_CustomerMail'     => 'john.doe@example.com',
    'psp_CardNumber'       => '4507990000000010', 
    'psp_CardExpDate'      => '1903', 
    'psp_CardSecurityCode' => '306',
    'psp_SoftDescriptor'   => 'Sol Tropical E',
    'psp_PosDateTime'      => '2016-12-01 12:00:00'
    
);
try{
    $resp = $sdk->payOnline2p($params);
}catch(ApiException $e){
    echo 'Code to handle error';
}

Environments

require_once __DIR__ . '/vendor/autoload.php';

use NpsSDK\Configuration;
use NpsSDK\Constants;
Configuration::environment(Constants::STAGING_ENV);
Configuration::environment(Constants::SANDBOX_ENV);
Configuration::environment(Constants::PRODUCTION_ENV);

Error handling

ApiException: This exception is raised when a ReadTimeout or a ConnectTimeout occurs.

Note: The rest of the exceptions that can occur will be detailed inside of the response provided by NPS or will be provided by the php SoapClient class.

}catch(ApiException $e){
    //Code to handle error
}

Advanced configurations

Logging

Nps SDK allows you to log what’s happening with you request inside of our SDK, it logs by default to stout. The SDK uses the custom logger that you use for your project.

An example for monolog Logger.

use Monolog\Logger;
$logger = new Logger(“NpsSdk”);

use NpsSDK\Configuration;

Configuration::secretKey(“your key here”);
Configuration::logger($logger);

LogLevel

Note: The logger needs to be PSR-3 compliant to work properly inside of the SDK, some examples are (Monolog, Analog).

The "INFO" level will write concise information of the request and will mask sensitive data of the request. The "DEBUG" level will write information about the request to let developers debug it in a more detailed way.

use NpsSDK\Configuration;

Configuration::secretKey(“your key here”);
Configuration::loglevel(“DEBUG”);

Sanitize

Sanitize allows the SDK to truncate to a fixed size some fields that could make request fail, like extremely long name.

use NpsSDK\Configuration;

Configuration::secretKey(“your key here”);
Configuration::sanitize(true);

Timeout

You can change the timeout of the request.

ExecutionTimeout(Default=60 seconds): you can change the execution timeout of the request.

ConnectionTimeout(Default=10 seconds): you can change the connection timeout of the request.

use NpsSDK\Configuration;

Configuration::secretKey(“your key here”);
Configuration::executionTimeout(60);
Configuration::connectionTimeout(10);

Proxy configuration

use NpsSDK\Configuration;

Configuration::secretKey(“your key here”);
Configuration::proxyUrl("http://yourproxy");
Configuration::proxyPort(6854);
Configuration::proxyUser("proxyUsername");
Configuration::proxyPass("proxyPassword");

Cache

use NpsSDK\Configuration;

Configuration::secretKey(“your key here”);
Configuration::useCache(True);
Configuration::cacheTTL(86400);
Configuration::cacheLocation("/tmp");
