README

This is a wrapper for Native Checkout V2 API of Viva Wallet: https://developer.vivawallet.com/native-checkout-v2/

How to use

This library is installed via Composer. You will need to require atdev/viva-php:

composer require atdev/viva-php:~1.0

Prerequisites

Complete prerequisite steps from https://developer.vivawallet.com/native-checkout-v2/ and obtain your Client ID and Client Secret. You'll need to set up a payment source with Native Checkout V2 as the integration method and get a Source Code.

Get card charge token

Create payment form and Charge Token at front end as described here: https://developer.vivawallet.com/native-checkout-v2/ You'll need to have Access Token and Base URL at front end and you can get them as follows:

$baseUrl = \ATDev\Viva\Transaction\Url::getUrl("[Test Mode]"); // Test mode, default is false

$accessToken = (new \ATDev\Viva\Account\Authorization())
	->setClientId("[Client ID]") // Client ID, Provided by wallet
	->setClientSecret("[Client Secret]") // Client Secret, Provided by wallet
	->setTestMode("[Test Mode]") // Test mode, default is false, can be skipped
	->getAccessToken();

Now, when you have Charge Token you can make actual transactions.

Transactions

CHARGE

$customer = (new \ATDev\Viva\Transaction\Customer())
	->setEmail("[Customer Email]")
	->setPhone("[Customer Phone]")
	->setFullName("[Customer Full Name]");

$transaction = (new ATDev\Viva\Transaction\Charge())
	->setClientId("[Client ID]") // Client ID, Provided by wallet
	->setClientSecret("[Client Secret]") // Client Secret, Provided by wallet
	->setTestMode("[Test Mode]") // Test mode, default is false, can be skipped
	->setSourceCode("[Source Code]") // Source code, provided by wallet
	->setAmount((int) "[Amount]") // The amount to charge in currency's smallest denomination (e.g amount in pounds x 100)
	->setInstallments((int) "[Installments]") // Installments, can be skipped if not used
	->setChargeToken("[Charge Token]") // Charge token obtained at front end
	->setCustomer($customer);

$result = $transaction->send();

if (!empty($transaction->getError())) {

	// Log the error message
	// $error = $transaction->getError();

} else {

	// Save transaction id
	// $transactionId = $result->transactionId;
}

AUTHORIZATION

$customer = (new \ATDev\Viva\Transaction\Customer())
	->setEmail("[Customer Email]")
	->setPhone("[Customer Phone]")
	->setFullName("[Customer Full Name]");

$transaction = (new ATDev\Viva\Transaction\Authorization())
	->setClientId("[Client ID]") // Client ID, Provided by wallet
	->setClientSecret("[Client Secret]") // Client Secret, Provided by wallet
	->setTestMode("[Test Mode]") // Test mode, default is false, can be skipped
	->setSourceCode("[Source Code]") // Source code, provided by wallet
	->setAmount((int) "[Amount]") // The amount to pre-auth in currency's smallest denomination (e.g amount in pounds x 100)
	->setInstallments((int) "[Installments]") // Installments, can be skipped if not used
	->setChargeToken("[Charge Token]") // Charge token obtained at front end
	->setCustomer($customer);

$result = $transaction->send();

if (!empty($transaction->getError())) {

	// Log the error message
	// $error = $transaction->getError();

} else {

	// Save transaction id
	// $transactionId = $result->transactionId;
}

CAPTURE

Make sure you have recurring payments enabled in your account.

$transaction = (new \ATDev\Viva\Transaction\Capture())
	->setClientId("[Client ID]") // Client ID, Provided by wallet
	->setClientSecret("[Client Secret]") // Client Secret, Provided by wallet
	->setTestMode("[Test Mode]") // Test mode, default is false, can be skipped
	->setTransactionId("[Transaction ID]") // Transaction id of authorization transaction
	->setAmount((int) "[Amount]"); // The amount to capture in currency's smallest denomination (e.g amount in pounds x 100)

$result = $transaction->send();

if (!empty($transaction->getError())) {

	// Log the error message
	// $error = $transaction->getError();
} else {

	// Save transaction id
	// $transactionId = $result->transactionId;
}

CANCEL

Make sure you have refunds enabled in your account.

$transaction = (new \ATDev\Viva\Transaction\Cancel())
	->setClientId("[Client ID]") // Client ID, Provided by wallet
	->setClientSecret("[Client Secret]") // Client Secret, Provided by wallet
	->setTestMode("[Test Mode]") // Test mode, default is false, can be skipped
	->setSourceCode("[Source Code]") // Source code, provided by wallet
	->setTransactionId("[Transaction ID]") // Transaction id of charge, authorization or capture transaction
	->setAmount((int) "[Amount]"); // The amount to refund in currency's smallest denomination (e.g amount in pounds x 100)

$result = $transaction->send();

if (!empty($transaction->getError())) {

	// Log the error message
	// $error = $transaction->getError();
} else {

	// Save transaction id
	// $transactionId = $result->transactionId;
}

Get charge token at backend

It's possible to get charge token at backend. It may be required in custom integration, more details can be found here: https://developer.vivawallet.com/native-checkout-v2/

$transaction = (new \ATDev\Viva\Transaction\ChargeToken())
	->setClientId("[Client ID]") // Client ID, Provided by wallet
	->setClientSecret("[Client Secret]") // Client Secret, Provided by wallet
	->setTestMode("[Test Mode]") // Test mode, default is false, can be skipped
	->setAmount((int) "[Amount]"); // The amount in currency's smallest denomination (e.g amount in pounds x 100)
	->setCvc("[Cvc code]") // Card cvc code
	->setNumber("[Card number]") // Card number
	->setHolderName("[Holder name]") // Card holder name
	->setExpirationYear((int) "[Expiration Year]") // Card expiration year
	->setExpirationMonth((int) "[Expiration Month]") // Card expiration month
	->setSessionRedirectUrl("[Session redirect url]"); // Url to redirect when authentication session finished

$result = $transaction->send();

if (!empty($transaction->getError())) {

	// Log the error message
	// $error = $transaction->getError();
} else {

	// Get charge token
	// $chargeToken = $result->chargeToken;
	// $redirectToACSForm = $result->redirectToACSForm;
}

Check for installments

Retrieve the maximum number of installments allowed on a card.

$transaction = (new \ATDev\Viva\Transaction\Installments())
	->setClientId("[Client ID]") // Client ID, Provided by wallet
	->setClientSecret("[Client Secret]") // Client Secret, Provided by wallet
	->setTestMode("[Test Mode]") // Test mode, default is false, can be skipped
	->setNumber("[Card number]"); // Card number

$result = $transaction->send();

if (!empty($transaction->getError())) {

	// Log the error message
	// $error = $transaction->getError();
} else {

	// Get number of installments
	// $installments = $result->maxInstallments;
}

Unit tests

Tests are run by ./vendor/bin/phpunit tests. Although the library code is designed to be compatible with php 5.6, testing requires php 7.3 as minimum because of phpunit version 9.
