A Laravel Package for working with Paystack seamlessly
PHP 5.4+ or HHVM 3.3+, and Composer are required.
To get the latest version of Laravel Paystack, simply require it
composer require unicodeveloper/laravel-paystack:2.0.0Or add the following line to the require block of your composer.json file.
"unicodeveloper/laravel-paystack": "2.0.*"
You'll then need to run composer install or composer update to download it and have the autoloader updated.
Once Laravel Paystack is installed, you need to register the service provider. Open up config/app.php and add the following to the providers key.
'providers' => [
...
Unicodeveloper\Paystack\PaystackServiceProvider::class,
...
]If you use Laravel >= 5.5 you can skip this step and go to
configuration
Unicodeveloper\Paystack\PaystackServiceProvider::class
Also, register the Facade like so:
'aliases' => [
...
'Paystack' => Unicodeveloper\Paystack\Facades\Paystack::class,
...
]You can publish the configuration file using this command:
php artisan vendor:publish --provider="Unicodeveloper\Paystack\PaystackServiceProvider"A configuration-file named paystack.php with some sensible defaults will be placed in your config directory:
<?php
return [
/**
* Public Key From Paystack Dashboard
*
*/
'publicKey' => env('PAYSTACK_PUBLIC_KEY'),
/**
* Secret Key From Paystack Dashboard
*
*/
'secretKey' => env('PAYSTACK_SECRET_KEY'),
/**
* Paystack Payment URL
*
*/
'paymentUrl' => env('PAYSTACK_PAYMENT_URL'),
/**
* Optional email address of the merchant
*
*/
'merchantEmail' => env('MERCHANT_EMAIL'),
// Maximum retry attempts for HTTP client (default: 3)
'retry_attempts' => env('PAYSTACK_RETRY_ATTEMPTS', 3),
// Delay (ms) between retry attempts (default: 150)
'retry_delay' => env('PAYSTACK_RETRY_DELAY', 150),
/*

];Though there are multiple ways to pay an order, most payment gateways expect you to follow the following flow in your checkout process:
After the customer has gone through the checkout process and is ready to pay, the customer must be redirected to the site of the payment provider.
The redirection is accomplished by submitting a form with some hidden fields. The form must send a POST request to the site of the payment provider. The hidden fields minimally specify the amount that must be paid, the order id and a hash.
The hash is calculated using the hidden form fields and a non-public secret. The hash used by the payment provider to verify if the request is valid.
The customer arrives on the site of the payment provider and gets to choose a payment method. All steps necessary to pay the order are taken care of by the payment provider.
After having paid the order the customer is redirected back. In the redirection request to the shop-site some values are returned. The values are usually the order id, a payment result and a hash.
The hash is calculated out of some of the fields returned and a secret non-public value. This hash is used to verify if the request is valid and comes from the payment provider. It is paramount that this hash is thoroughly checked.
Open your .env file and add your public key, secret key, merchant email and payment url like so:
PAYSTACK_PUBLIC_KEY=xxxxxxxxxxxxx
PAYSTACK_SECRET_KEY=xxxxxxxxxxxxx
PAYSTACK_PAYMENT_URL=https://api.paystack.co
MERCHANT_EMAIL=unicodeveloper@gmail.comIf you are using a hosting service like heroku, ensure to add the above details to your configuration variables.
Set up routes and controller methods like so:
Note: Make sure you have /payment/callback registered in Paystack Dashboard https://dashboard.paystack.co/#/settings/developer like so:
Route::get('/payment', [App\Http\Controllers\PaymentController::class, 'index'])->name('payment.form');
Route::post('/checkout', [App\Http\Controllers\PaymentController::class, 'redirectToGateway'])->name('checkout.process');
Route::get('/payment/callback', [App\Http\Controllers\PaymentController::class, 'handleGatewayCallback'])->name('payment.callback');
<?php

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Log;

Paystack::transRef();When clicking the submit button the customer gets redirected to the Paystack site.
So now we've redirected the customer to Paystack. The customer did some actions there (hopefully he or she paid the order) and now gets redirected back to our shop site.
Paystack will redirect the customer to the url of the route that is specified in the Callback URL of the Web Hooks section on Paystack dashboard.
