laravel-nowpayments

A Laravel Package for working with NOWPayments seamlessly

This package comes now with a default dashboard that show the list of all payments and also shows a log of endpoints that have been accessed from your application, fluent methods to handle payments easily and removes the bulk of the heavy work from you.

Installation

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

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

composer require prevailexcel/laravel-nowpayments

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

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

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

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

'providers' => [
    ...
    PrevailExcel\Nowpayments\NowpaymentsServiceProvider::class,
    ...
]

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

• PrevailExcel\Nowpayments\NowpaymentsServiceProvider::class

Also, register the Facade like so:

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

Configuration

You can publish the configuration file using this command:

php artisan vendor:publish --provider="PrevailExcel\Nowpayments\NowpaymentsServiceProvider"

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

<?php


return [

    /**
     * API Key From NOWPayments Dashboard
     *
     */
    'apiKey' => env('NOWPAYMENTS_API_KEY'),
    
    /**
     * IPN Secret from NOWPayments Dashboard
     */
    'ipnSecret' => env('NOWPAYMENTS_IPN_SECRET'),
    
    /**
     * You enviroment can either be live or sandbox.
     * Make sure to add the appropriate API key after changing the enviroment in .env
     *
     */
    'env' => env('NOWPAYMENTS_ENV', 'sandbox'),

    /**
     * NOWPayments Live URL
     *
     */
    'liveUrl' => env('NOWPAYMENTS_LIVE_URL', "https://api.nowpayments.io/v1"),

    /**
     * NOWPayments Sandbox URL
     *
     */
    'sandboxUrl' => env('NOWPAYMENTS_SANDBOX_URL', "https://api-sandbox.nowpayments.io/v1"),

    /**
     * Your callback URL
     *
     */
    'callbackUrl' => env('NOWPAYMENTS_CALLBACK_URL'),

    /**
     * Your URL Path
     *
     */
    'path' => 'laravel-nowpayments',

    /**
     * You can add your custom middleware to access the dashboard here
     *
     */
    'middleware' => null, // "Authorise::class",

    /**
     * Your Nowpayment email here
     *
     */
    'email' => env('NOWPAYMENTS_EMAIL'),
    
    /**
     * Your Nowpayment password here
     *
     */
    'password' =>  env('NOWPAYMENTS_PASSWORD'),
];

Remeber to run your migration to add one table to the database for logging with this command

php artisan migrate

You can test the dashboard to see if your set up is ready by serving your application and going to /laravel-nowpayments

127.0.0.1:8000/laravel-nowpayments

You can change this default path/url by changing the 'path' from the config file at nowpayments.php in your config folder

<?php

return [
    ...
    // 'path' => 'laravel-nowpayments',
    'path' => 'new-endpoint',
];

General E-commerce Payment Flow

1 UI - Ask a customer to select item/items for purchase to determine the total sum

2 UI - Ask a customer to select payment currency

3 API - Call Nowpayments::createPayment() method;

Pass the data from the User as an array. This method does the magic. First it gets the minimum payment amount for the currency pair, then it gets the estimate of the total amount in crypto and checks that it is larger than the minimum payment amount.

If it's true, it sends the payload and gets the payment data that inclues the generated wallet address for the user.

4 UI - Ask a customer to send the payment to the generated deposit address.

5 UI - A customer sends coins, NOWPayments processes and exchanges them (if required), and settles the payment to your Outcome Wallet.

6 API - Check the payment status

You can get the payment status either via NOWPayments IPN callbacks or manually using "nowpayments()->getPaymentStatus()" and display it to a customer so that they know when their payment has been processed.

7 Check the dashboard for a list of all your payments

This package comes with a default Dashboard that show a list of all payments and also shows a log of endpoints thta have been accessed from your application. Additionally, you can see all of this information in your Account on NOWPayments website.

Usage

Open your .env file and add your api key, env, callback url like so:

NOWPAYMENTS_ENV="live"
NOWPAYMENTS_API_KEY="*******-*******-*******-*******"
NOWPAYMENTS_CALLBACK_URL="https://yourcallback.com"
NOWPAYMENTS_EMAIL="[email protected]"
NOWPAYMENTS_PASSWORD="your password"

If you are using a hosting service like heroku, ensure to add the above details to your configuration variables.

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

OR

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

OR

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

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Redirect;
use PrevailExcel\Nowpayments\Facades\Nowpayments;

class PaymentController extends Controller
{

    /**
     * Collect Order data and create Payment
     * @return Url
     */
    public function createCryptoPayment()
    {
        try{
            $data = [
                'price_amount' => request()->price_amount ?? 100,
                'price_currency' => request()->price_currency ?? 'usd',
                'order_id' => request()->order_id ?? uniqid(), // you can generate your order id as you wish
                'pay_currency' => request()->pay_currency ?? 'btc',
                'payout_currency' => request()->payout_currency ?? 'btc',
            ];

           $paymentDetails = Nowpayments::createPayment($data);
            
            dd($paymentDetails);
            // Now you have the payment details,
            // you can then redirect or do whatever you want

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