Documentation and Examples

You can find the latest SDK documentation along with code examples and test cards on the GlobalPayments and GlobalPayments Developer Hubs.

In addition you can find working examples in the our example code repository.

Quick Tip: The included test suite can be a great source of code samples for using the SDK!

Process a Payment Example

$card = new CreditCardData();
$card->number = "4111111111111111";
$card->expMonth = "12";
$card->expYear = "2025";
$card->cvn = "123";

try {
    $response = $card->charge(129.99)
        ->withCurrency("EUR")
        ->execute();

    $result = $response->responseCode; // 00 == Success
    $message = $response->responseMessage; // [ test system ] AUTHORISED
} catch (ApiException $e) {
    // handle errors
}

GP-API Access Token

The SDK supports creating GP-API access tokens with full control over token configuration and complete response field mapping.

Generate an Access Token

use GlobalPayments\Api\Entities\Enums\Channel;
use GlobalPayments\Api\Entities\Enums\Environment;
use GlobalPayments\Api\Entities\Enums\IntervalToExpire;
use GlobalPayments\Api\ServiceConfigs\Gateways\GpApiConfig;
use GlobalPayments\Api\Services\GpApiService;

$config = new GpApiConfig();
$config->appId = 'your-app-id';
$config->appKey = 'your-app-key';
$config->environment = Environment::TEST;
$config->channel = Channel::CardNotPresent;

// Optional: control token expiration
$config->secondsToExpire = 3600;
$config->intervalToExpire = IntervalToExpire::ONE_HOUR;

// Optional: scope the token to specific permissions
$config->permissions = ['TRN_POST_Authorize', 'TRN_POST_Capture'];

// Optional: create a restricted token for Drop-in UI / Hosted Fields
$config->restrictedToken = true;

$accessTokenInfo = GpApiService::generateTransactionKey($config);

Available Request Fields

Field	Type	Description
appId	string	Application identifier (required)
appKey	string	Application key (required)
secondsToExpire	int	Token TTL in seconds (60–604800)
intervalToExpire	string	Token TTL as interval (WEEK, DAY, 1_HOUR, etc.)
permissions	array	Permission strings to scope the token
restrictedToken	bool	When true, masks account info in the response

Available Response Fields

$accessTokenInfo->accessToken;       // Bearer token string
$accessTokenInfo->tokenType;         // "Bearer"
$accessTokenInfo->appId;             // Application ID
$accessTokenInfo->appName;           // Application name
$accessTokenInfo->merchantId;        // Merchant ID (MER_...)
$accessTokenInfo->merchantName;      // Merchant name
$accessTokenInfo->email;             // Associated email
$accessTokenInfo->timeCreated;       // ISO-8601 creation timestamp
$accessTokenInfo->secondsToExpire;   // TTL in seconds
$accessTokenInfo->intervalToExpire;  // TTL interval enum

Testing Exceptions

During your integration you will want to test for specific issuer responses such as 'Card Declined'. Because our sandbox environments do not actually reach out to issuing banks for authorizations, there are specific transaction amounts and/or card numbers that will trigger gateway and issuing bank responses. Please contact your support representative for a complete listing of values used to simulate transaction AVS/CVV results, declines, errors, and other responses that can be caught in your code. Example error handling code:

try {
    $response = $card->charge(129.99)
        ->withCurrency("EUR")
        ->execute();
} catch (BuilderException $e) {
    // handle builder errors
} catch (ConfigurationException $e) {
    // handle errors related to your services configuration
} catch (GatewayException $e) {
    // handle gateway errors/exceptions
} catch (UnsupportedTransactionException $e) {
    // handle errors when the configured gateway doesn't support
    // desired transaction
} catch (ApiException $e) {
    // handle all other errors
}
