use TarlanPayments\Gateway\Gateway;

$gw = new Gateway();

// Setup gateway authorization credentials
$gw->auth()
    ->setAccountGUID("3383e58e-9cde-4ffa-85cf-81cd25b2423e")
    ->setSecretKey('super-secret-key');

// Create transaction object
$sms = $gw->createSms();

// Set required fields
$sms->money()
    ->setAmount(100)
    ->setCurrency('USD');

$sms->customer()
    ->setEmail("email@domain.com")
    ->setPhone("2445224657");

$sms->order()
    ->setMerchantTransactionID('A-345S')
    ->setDescription('Order #A-345S payment');

// Process payment via gateway inside form
$sms->insideForm();

// Build transaction object to request
$smsRequest = $sms->build();

// Process transaction to gateway
$response = $gw->process($smsRequest);

Server to server

Hold card input form on merchant side and process via API., _(*4)

<?php

use TarlanPayments\Gateway\Gateway;

$gw = new Gateway();

// Setup gatewayl authorization credentials
$gw->auth()

Documentation

This README provide introduction to the library usage., _(*5)

Operations

Operations are available via $gw->create<operation name>() method., _(*6)

Available operations: - Transactions - CANCEL - DMS CHARGE - DMS HOLD - MOTO DMS - MOTO SMS - INIT RECURRENT DMS - RECURRENT DMS - INIT RECURRENT SMS - RECURRENT SMS - REFUND - REVERSAL - SMS - Credit - P2P - B2P - Information - HISTORY - RECURRENTS - REFUNDS - RESULT - STATUS - Verification - 3-D Secure enrollment - Complete card verification - Tokenization - Create payment data token, _(*7)

Pattern to work with the library can be described as follows:, _(*8)

<?php

use TarlanPayments\Gateway\Gateway;

$gw = new Gateway();

// first, you need to setup authorization.
// you can change authorization data in runtime.
// Thus, following operations will work under
// new authorization.
$gw->auth()
    ->setAccountGUID("3383e58e-9cde-4ffa-85cf-81cd25b2423e")
    ->setSecretKey('super-secret-key');

$operation = $gw->createOPERATION();

// here you setup your request through public methods
// that expose you blocks of information, that you can fill for the
// operation of your choice.

// build() will prepare `Request` object that `$gw` will use
// for the request.
$operationRequest = $operation->build();

// process() will perform provided request to the gateway
// `$response` will have response data (headers, body).
$response = $gw->process($operationRequest);

Card verification

<?php

use TarlanPayments\Gateway\DataSets\Command;

// create a payment to init card verification process
$message->command()->setCardVerificationMode(Command::CARD_VERIFICATION_MODE_INIT);

// complete card verification
$operation = $gw->createCardVerification();
$operation->data()->setGatewayTransactionID($initialResponseGatewayTransactionId);
$operationRequest = $operation->build();
$response = $gw->process($request);

// send a payment with flag to accept only verified cards
$message->command()->setCardVerificationMode(Command::CARD_VERIFICATION_MODE_VERIFY);

Payment data tokenization

<?php

use TarlanPayments\Gateway\DataSets\Command;

// option 1: create a payment with flag to save payment data
$message->command()->setPaymentMethodDataSource(Command::DATA_SOURCE_SAVE_TO_GATEWAY);

// option 2: send "create token" request with payment data
$operation = $gw->createToken();
$operation->paymentMethod()
    ->setPAN('<card number>')
    ->setExpire('<card expiry>')
    ->setCardHolderName('<cardholder name>');
$operation->money()
    ->setCurrency('<desired currency>');
$operationRequest = $operation->build();
$response = $gw->process($request);

// send a payment in "token usage" mode with flag to load payment data by token
$message->useToken();
$message->command()
    ->setPaymentMethodDataSource(Command::DATA_SOURCE_USE_GATEWAY_SAVED_CARDHOLDER_INITIATED)
    ->setPaymentMethodDataToken('<initial gateway-transaction-id>');

Customization

If you need to access different API URL you can set through Gateway constructor as follows:, _(*9)

<?php

use TarlanPayments\Gateway\Gateway;

$gw = new Gateway('https://customurl.com');

Also, you can customize client for your needs. By default Http\Client\Client class is used. It use cURL under the hood. It implements HttpClientInterface. You can create your own (or configure default) and set it to the gateway., _(*10)

<?php

use TarlanPayments\Gateway\Gateway;

$httpClient = new MyClient(); // implements HttpClientInterface

$gw = new Gateway();
$gw->setHttpClient($httpClient);

// use it!
// ...
