A Laravel Package for working with Coinremitter seamlessly

Installation

PHP 5.4+ or HHVM 3.3+, and Composer are required.

To get the latest version of Laravel Coinremitter, simply require it

composer require prevailexcel/laravel-coinremitter

Or add the following line to the require block of your composer.json file.

"prevailexcel/laravel-coinremitter": "1.0.*"

You'll then need to run composer install or composer update to download it and have the autoloader updated.

Once Laravel Coinremitter is installed, you need to register the service provider. Open up config/app.php and add the following to the providers key.

If you use Laravel >= 5.5 you can skip this step and go to configuration

'providers' => [
    ...
    PrevailExcel\Coinremitter\CoinremitterServiceProvider::class,
    ...
]

• PrevailExcel\Coinremitter\CoinremitterServiceProvider::class

Also, register the Facade like so:

'aliases' => [
    ...
    'Coinremitter' => PrevailExcel\Coinremitter\Facades\Coinremitter::class,
    ...
]

Configuration

You can publish the configuration file using this command:

php artisan vendor:publish --provider="PrevailExcel\Coinremitter\CoinremitterServiceProvider"

A configuration-file named coinremitter.php with some sensible defaults will be placed in your config directory:

<?php

return [

    'coins' => [

        'BTC' => [
            'api_key' => 'API_KEY_FROM_WEBSITE',
            'password' => 'PASSWORD',
        ],

        'LTC' => [
            'api_key' => 'API_KEY_FROM_WEBSITE',
            'password' => 'PASSWORD',
        ],
    ],
];

General payment flow

Though there are multiple ways to pay an order, most payment gateways expect you to follow the following flow in your checkout process:

1. The customer is redirected to the payment provider

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.

2. The customer pays on the site of the payment provider

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.

3. The customer gets redirected back to your site

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.

Usage

When using Facade or Helper, request()->coin = 'COIN' must be used to pass the coin. If not, use

use PrevailExcel\Coinremitter\Coinremitter;

$coinremitter = new Coinremitter('COIN');
$coinremitter->balance();

1. Redirect User to GateWay

// Laravel 5.1.17 and above
Route::post('/pay', 'PaymentController@redirectToGateway')->name('pay');

OR

Route::post('/pay', [
    'uses' => 'PaymentController@redirectToGateway',
    'as' => 'pay'
]);

OR

// Laravel 8 & 9
Route::post('/pay', [App\Http\Controllers\PaymentController::class, 'redirectToGateway'])->name('pay');

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Redirect;
use PrevailExcel\Coinremitter\Facades\Coinremitter;

class PaymentController extends Controller
{
    
    public function __construct()
    {
        if(!request()->coin)
            request()->coin = 'BTC'; //set a default coin
    }

    /**
     * Collect Order data and Redirect user to Payment gateway
     */
    public function redirectToGateway()
    {
        try{
            //You should collect the details you need from a form

           return Coinremitter::redirectToGateway();

           // or alternatively use the helper
           return coinremitter()->redirectToGateway();
            
        }catch(\Exception $e) {
            return Redirect::back()->withMessage(['msg'=>"There's an error in the data", 'type'=>'error']);
        }        
    }
}

/**
 *  In the case where you need to pass the data from your 
 *  controller instead of a form
 *  Make sure to send:
 *  required: amount, currency
 *  optionally: name, expire_time, notify_url, suceess_url, description, custom_data1,custom_data2'
 *  e.g:
 *  
 */
$data = array(
            'amount' => 500, //required
            'name' => 'random-name', //Name accepts only numbers, letters, hyphens.
            'currency' => 'usd',
            'expire_time' => '20', //optional, invoice will expire in 20 minutes. 
            'notify_url'=>'https://yourdomain.com/notify-url', //optional,url on which you wants to receive notification
            'fail_url' => 'https://yourdomain.com/fail-url', //optional,url on which user will be redirect if user cancel invoice,
            'suceess_url' => 'https://yourdomain.com/success-url', //optional,url on which user will be redirect when invoice paid,    
            'description' => '',
            'custom_data1' => '',
            'custom_data2' => '',
        );

return Coinremitter::redirectToGateway($data);

// or alternatively use the helper
return coinremitter()->redirectToGateway($data);

2. If you want to use your own UI

Without redirecting User to Coinremitter Payment page, you use Coinremitter::createInvoice()like shown below.

// Laravel 5.1.17 and above
Route::post('/get-invoice', 'PaymentController@createCryptoPayment')->name('get.invoice');

OR

Route::post('/get-invoice', [
    'uses' => 'PaymentController@createCryptoPayment',
    'as' => 'get.invoice'
]);

OR

// Laravel 8 & 9
Route::post('/get-invoice', [App\Http\Controllers\PaymentController::class, 'createCryptoPayment'])->name('get.invoice');

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Redirect;
use PrevailExcel\Coinremitter\Facades\Coinremitter;

class PaymentController extends Controller
{
    
    public function __construct()
    {
        if(!request()->coin)
            request()->coin = 'BTC'; //set a default coin
    }

    /**
     * Collect Order data and Redirect user to Payment gateway
     */
    public function createCryptoPayment()
    {
        try{
            //You should collect the details you need from a form

            $invoiceDetails = Coinremitter::createInvoice();

            // or alternatively use the helper
            $invoiceDetails = coinremitter()->createInvoice();


            dd($invoiceDetails);
            // Now you have the payment details,
            // you can store the authorization_code in your db to allow for recurrent subscriptions
            // you can then redirect or do whatever you want

            
        }catch(\Exception $e) {
            return Redirect::back()->withMessage(['msg'=>"There's an error in the data", 'type'=>'error']);
        }        
    }
}

/**
 *  In the case where you need to pass the data from your 
 *  controller instead of a form

 *  optionally: name, expire_time, notify_url, suceess_url, description, custom_data1,custom_data2'
 *  e.g:
 *  
 */
$data = array(
            'amount' => 500, //required
            'name' => 'random-name', //Name accepts only numbers, letters, hyphens.
            'currency' => 'usd',
            'expire_time' => '20', //optional, invoice will expire in 20 minutes. 
            'notify_url'=>'https://yourdomain.com/notify-url', //optional,url on which you wants to receive notification
            'fail_url' => 'https://yourdomain.com/fail-url', //optional,url on which user will be redirect if user cancel invoice,
            'suceess_url' => 'https://yourdomain.com/success-url', //optional,url on which user will be redirect when invoice paid,    
            'description' => '',
            'custom_data1' => '',
            'custom_data2' => '',
        );

$invoiceDetails = Coinremitter::createInvoice($data);

// or alternatively use the helper
$invoiceDetails = coinremitter()->createInvoice($data);


dd($invoiceDetails);
// Now you have the payment details,
// you can store the authorization_code in your db to allow for recurrent subscriptions
// you can then redirect or do whatever you want
