you can create your own custom drivers if it doesn't exist in the list, read the Create custom drivers section.

Install

Via Composer

composer require shetabit/multipay

Configure

a. Copy config/payment.php into somewhere in your project. (you can also find it in vendor/shetabit/multipay/config/payment.php path).

b. In the config file you can set the default driver to be used for all your payments and you can also change the driver at runtime.

Choose what gateway you would like to use in your application. Then make that as default driver so that you don't have to specify that everywhere. But, you can also use multiple gateways in a project.

// Eg. if you want to use zarinpal.
'default' => 'zarinpal',

Then fill the credentials for that gateway in the drivers array.

'drivers' => [
    'zarinpal' => [
        // Fill in the credentials here.
        'apiPurchaseUrl' => 'https://www.zarinpal.com/pg/rest/WebGate/PaymentRequest.json',
        'apiPaymentUrl' => 'https://www.zarinpal.com/pg/StartPay/',
        'apiVerificationUrl' => 'https://www.zarinpal.com/pg/rest/WebGate/PaymentVerification.json',
        'merchantId' => '',
        'callbackUrl' => 'http://yoursite.com/path/to',
        'description' => 'payment in '.config('app.name'),
    ],
    ...
]

c. Instantiate the Payment class and pass configs to it like the below:

    use Shetabit\Multipay\Payment;

    // load the config file from your project
    $paymentConfig = require('path/to/payment.php');

    $payment = new Payment($paymentConfig);

How to use

your Invoice holds your payment details, so initially we'll talk about Invoice class.

Working with invoices

before doing any thing you need to use Invoice class to create an invoice.

In your code, use it like the below:

// At the top of the file.
use Shetabit\Multipay\Invoice;
...

// Create new invoice.
$invoice = new Invoice;

// Set invoice amount.
$invoice->amount(1000);

// Add invoice details: There are 4 syntax available for this.
// 1
$invoice->detail(['detailName' => 'your detail goes here']);
// 2 
$invoice->detail('detailName','your detail goes here');
// 3
$invoice->detail(['name1' => 'detail1','name2' => 'detail2']);
// 4
$invoice->detail('detailName1','your detail1 goes here')
        ->detail('detailName2','your detail2 goes here');

Available methods:

uuid: set the invoice unique id
getUuid: retrieve the invoice current unique id
detail: attach some custom details into invoice
getDetails: retrieve all custom details
amount: set the invoice amount
getAmount: retrieve invoice amount
transactionId: set invoice payment transaction id
getTransactionId: retrieve payment transaction id
via: set a driver we use to pay the invoice
getDriver: retrieve the driver

Purchase invoice

In order to pay the invoice, we need the payment transactionId. We purchase the invoice to retrieve transaction id:

// At the top of the file.
use Shetabit\Multipay\Invoice;
use Shetabit\Multipay\Payment;
...

// load the config file from your project
$paymentConfig = require('path/to/payment.php');

$payment = new Payment($paymentConfig);


// Create new invoice.
$invoice = (new Invoice)->amount(1000);

// Purchase the given invoice.
$payment->purchase($invoice,function($driver, $transactionId) {
	// We can store $transactionId in database.
});

// Purchase method accepts a callback function.
$payment->purchase($invoice, function($driver, $transactionId) {
    // We can store $transactionId in database.
});

// You can specify callbackUrl
$payment->callbackUrl('http://yoursite.com/verify')->purchase(
    $invoice,
    function($driver, $transactionId) {
    	// We can store $transactionId in database.
	}
);

Pay invoice

After purchasing the invoice, we can redirect the user to the bank payment page:

// At the top of the file.
use Shetabit\Multipay\Invoice;
use Shetabit\Multipay\Payment;
...

// load the config file from your project
$paymentConfig = require('path/to/payment.php');

$payment = new Payment($paymentConfig);


// Create new invoice.
$invoice = (new Invoice)->amount(1000);

// Purchase and pay the given invoice.
// You should use return statement to redirect user to the bank page.
return $payment->purchase($invoice, function($driver, $transactionId) {
    // Store transactionId in database as we need it to verify payment in the future.
})->pay()->render();

// Do all things together in a single line.
return $payment->purchase(
    (new Invoice)->amount(1000), 
    function($driver, $transactionId) {
    	// Store transactionId in database.
        // We need the transactionId to verify payment in the future.
	}
)->pay()->render();

// Retrieve json format of Redirection (in this case you can handle redirection to bank gateway)
return $payment->purchase(
    (new Invoice)->amount(1000), 
    function($driver, $transactionId) {
    	// Store transactionId in database.
        // We need the transactionId to verify payment in the future.
	}
)->pay()->toJson();

Verify payment

When user has completed the payment, the bank redirects them to your website, then you need to verify your payment in order to ensure the invoice has been paid.

// At the top of the file.
use Shetabit\Multipay\Payment;
use Shetabit\Multipay\Exceptions\InvalidPaymentException;
...

// load the config file from your project
$paymentConfig = require('path/to/payment.php');

$payment = new Payment($paymentConfig);


// You need to verify the payment to ensure the invoice has been paid successfully.
// We use transaction id to verify payments
// It is a good practice to add invoice amount as well.
try {
	$receipt = $payment->amount(1000)->transactionId($transaction_id)->verify();

    // You can show payment referenceId to the user.
    echo $receipt->getReferenceId();

    ...
} catch (InvalidPaymentException $exception) {
    /**
    	when payment is not verified, it will throw an exception.
    	We can catch the exception to handle invalid payments.
    	getMessage method, returns a suitable message that can be used in user interface.
    **/
    echo $exception->getMessage();
}

Useful methods

`callbackUrl`: can be used to change callbackUrl on the runtime.

// At the top of the file.
use Shetabit\Multipay\Invoice;
use Shetabit\Multipay\Payment;
...

// load the config file from your project
$paymentConfig = require('path/to/payment.php');

$payment = new Payment($paymentConfig);


// Create new invoice.
$invoice = (new Invoice)->amount(1000);

// Purchase the given invoice.
$payment->callbackUrl($url)->purchase(
    $invoice, 
    function($driver, $transactionId) {
    // We can store $transactionId in database.
	}
);

`amount`: you can set the invoice amount directly

// At the top of the file.
use Shetabit\Multipay\Invoice;
use Shetabit\Multipay\Payment;
...

// load the config file from your project
$paymentConfig = require('path/to/payment.php');

$payment = new Payment($paymentConfig);


// Purchase (we set invoice to null).
$payment->callbackUrl($url)->amount(1000)->purchase(
    null,
    function($driver, $transactionId) {
    // We can store $transactionId in database.
	}
);

`via`: change driver on the fly

// At the top of the file.
use Shetabit\Multipay\Invoice;
use Shetabit\Multipay\Payment;
...

// load the config file from your project
$paymentConfig = require('path/to/payment.php');

$payment = new Payment($paymentConfig);


// Create new invoice.
$invoice = (new Invoice)->amount(1000);

// Purchase the given invoice.
$payment->via('driverName')->purchase(
    $invoice, 
    function($driver, $transactionId) {
    // We can store $transactionId in database.
	}
);

`config`: set driver configs on the fly

// At the top of the file.
use Shetabit\Multipay\Invoice;
use Shetabit\Multipay\Payment;
...

// load the config file from your project
$paymentConfig = require('path/to/payment.php');

$payment = new Payment($paymentConfig);


// Create new invoice.
$invoice = (new Invoice)->amount(1000);

// Purchase the given invoice with custom driver configs.
$payment->config('mechandId', 'your mechand id')->purchase(
    $invoice,
    function($driver, $transactionId) {
    // We can store $transactionId in database.
	}
);

// Also we can change multiple configs at the same time.
$payment->config(['key1' => 'value1', 'key2' => 'value2'])->purchase(
    $invoice,
    function($driver, $transactionId) {
    // We can store $transactionId in database.
	}
);

custom fileds: Use custom fields of gateway (Not all gateways support this feature) SEP gateway support up to 4 custom fields and you can set the value to a string up to 50 characters. These custom fields are shown only when viewing reports in the user's panel.

// At the top of the file.
use Shetabit\Multipay\Invoice;
...


// Create new invoice.
$invoice = (new Invoice)->amount(1000);

// Use invoice bag to store custom field values.
$invoice->detail([
            'ResNum1' => $order->orderId,
            'ResNum2' => $customer->verifiedCode,
            'ResNum3' => $someValue,
            'ResNum4' => $someOtherValue,
            ]);

Create custom drivers:

First you have to add the name of your driver, in the drivers array and also you can specify any config parameters you want.

'drivers' => [
    'zarinpal' => [...],
    'my_driver' => [
        ... // Your Config Params here.
    ]
]

Now you have to create a Driver Map Class that will be used to pay invoices. In your driver, You just have to extend Shetabit\Multipay\Abstracts\Driver.

Eg. You created a class: App\Packages\Multipay\Driver\MyDriver.

namespace App\Packages\Multipay\Driver;

use Shetabit\Multipay\Abstracts\Driver;
use Shetabit\Multipay\Exceptions\InvalidPaymentException;
use Shetabit\Multipay\{Contracts\ReceiptInterface, Invoice, RedirectionForm, Receipt};

class MyDriver extends Driver
{
    protected $invoice; // Invoice.

    protected $settings; // Driver settings.

    public function __construct(Invoice $invoice, $settings)
    {
        $this->invoice($invoice); // Set the invoice.
        $this->settings = (object) $settings; // Set settings.
    }

    // Purchase the invoice, save its transactionId and finaly return it.
    public function purchase() {
        // Request for a payment transaction id.
        ...

        $this->invoice->transactionId($transId);

        return $transId;
    }

    // Redirect into bank using transactionId, to complete the payment.
    public function pay() : RedirectionForm {
        // It is better to set bankApiUrl in config/payment.php and retrieve it here:
        $bankUrl = $this->settings->bankApiUrl; // bankApiUrl is the config name.

        // Prepare payment url.
        $payUrl = $bankUrl.$this->invoice->getTransactionId();

        // Redirect to the bank.
        $url = $payUrl;
        $inputs = [];
        $method = 'GET';

        return $this->redirectWithForm($url, $inputs, $method);
    }
  
    // Verify the payment (we must verify to ensure that user has paid the invoice).
    public function verify(): ReceiptInterface {
        $verifyPayment = $this->settings->verifyApiUrl;
  
        $verifyUrl = $verifyPayment.$this->invoice->getTransactionId();
  
        ...
  
        /**
			Then we send a request to $verifyUrl and if payment is not valid we throw an InvalidPaymentException with a suitable message.
        **/
        throw new InvalidPaymentException('a suitable message');
  
        /**
        	We create a receipt for this payment if everything goes normally.
        **/
        return new Receipt('driverName', 'payment_receipt_number');
    }
}

Once you create that class you have to specify it in the payment.php config file map section.

'map' => [
    ...
    'my_driver' => App\Packages\Multipay\Driver\MyDriver::class,
]

Note: You have to make sure that the key of the map array is identical to the key of the drivers array.

Events:

Notice 1: event listeners will be registered globaly for all payments.

Notice 2: if you want your listeners work correctly, you must subcribe them before the target event dispatches.

Its better to subcribe events in your app's entry point or main service provider, so events will be subcribed before any events dispatches.

You can listen for 3 events:

purchase
pay
verify.

purchase: Occurs when an invoice is purchased (after purchasing invoice is done successfully).

// add purchase event listener
Payment::addPurchaseListener(function($driver, $invoice) {
    echo $driver;
    echo $invoice;
});

pay: Occurs when an invoice is prepared to pay.

// add pay event listener
Payment::addPayListener(function($driver, $invoice) {
    echo 'first listener';
});

// we can add multiple listeners
Payment::addPayListener(function($driver, $invoice) {
    echo 'second listener';
});

verify: Occurs when an invoice is verified successfully.

// we can add multiple listeners and also remove them!!!

$firstListener = function($driver, $invoice) {
    echo 'first listener';
};

$secondListener = function($driver, $invoice) {
    echo 'second listener';
};

Payment::addVerifyListener($firstListener);
Payment::addVerifyListener($secondListener);

// remove first listener
Payment::removeVerifyListener($firstListener);

// if we call remove listener without any arguments, it will remove all listeners
Payment::removeVerifyListener(); // remove all verify listeners :D

Local driver

Local driver can simulate payment flow of a real gateway for development purpose.

Payment can be initiated like any other driver

$invoice = (new Invoice)->amount(10000);
$payment->via('local')->purchase($invoice, function($driver, $transactionId) {
    // a fake transaction ID is generated and returned.
})->pay()->render();

Calling render() method will render a HTML form with Accept and Cancel buttons, which simulate corresponding action of real payment gateway. and redirects to the specified callback url. transactionId parameter will allways be available in the returned query url.

Payment can be verified after receiving the callback request.

$receipt = $payment->via('local')->verify();

In case of succesful payment, $receipt will contains the following parameters

[
'orderId' => // fake order number 
'traceNo' => // fake trace number (this should be stored in databse)
'referenceNo' => // generated transaction ID in `purchase` method callback
'cardNo' => // fake last four digits of card 
]

In case of canceled payment, PurchaseFailedException will be thrown to simulate the failed verification of gateway.

Driver functionalities can be configured via Invoice detail bag.

available parameters

$invoice->detail([
    // setting this value will cause `purchase` method to throw an `PurchaseFailedException` 
    // to simulate when a gateway can not initialize the payment.
        'failedPurchase' => 'custom message to decribe the error',

    // Setting this parameter will be shown in payment form.
        'orderId' => 4444,
]);

appearance

Appearance of payment form can be customized via config parameter of local driver in payment.php file.

'local' => [
    // default callback url of the driver
    'callbackUrl' => '/callback',

    // main title of the form
    'title' => 'Test gateway',
  
    // a description to show under the title for more clarification
    'description' => 'This gateway is for using in development environments only.',
  
    // custom label to show as order No.
    'orderLabel' => 'Order No.',
  
    // custom label to show as payable amount
    'amountLabel' => 'Payable amount',
  
    // custom label of successful payment button
    'payButton' => 'Successful Payment',
  
    // custom label of cancel payment button
    'cancelButton' => 'Cancel Payment',
],
