Installation

Install package

You can install the package via composer:

composer require vrajroham/laravel-bitpay

Publish config file

Publish config file with:

php artisan vendor:publish --provider="Vrajroham\LaravelBitpay\LaravelBitpayServiceProvider"

Add configuration values

Add following keys to .env file and updated the details (view more about configuration):

BITPAY_PRIVATE_KEY_PATH=/tmp/bitpay.pri
BITPAY_PUBLIC_KEY_PATH=/tmp/bitpay.pub
BITPAY_NETWORK=testnet
BITPAY_KEY_STORAGE_PASSWORD=SomeRandomePasswordForKeypairEncryption
BITPAY_TOKEN=

Add webhook event listener

By default package is capable of handling of webhook requests. Bitpay payment status updates are completely based on webhooks. Whenever webhook is received from server, BitpayWebhookReceived event is dispatched. You just need to provide a listener for this event.

You can add your listener as below,

<?php

namespace App\Listeners;

use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
use Vrajroham\LaravelBitpay\Events\BitpayWebhookReceived;

class ProcessBitpayWebhook
{
    /**
     * Create the event listener.
     */
    public function __construct()
    {
    }

    /**
     * Handle the event.
     *
     * @param object $event
     */
    public function handle(BitpayWebhookReceived $event)
    {
        $orderId = $event->payload['orderId'];
        $status = $event->payload['status'];
        // Other payload properties
        // You will receive 3 webhooks for single payment with different status.
        // 1. status = paid
        // 2. status = confirmed
        // 3. status = completed
    }
}

Next, add listener to EventServiceProvider's $listen array as below,

<?php

class EventServiceProvider extends ServiceProvider{
    protected $listen = [
        // Other events and listeners
        BitpayWebhookReceived::class => [
            ProcessBitpayWebhook::class,
        ],
    ];

    public function boot()
    {
        parent::boot();
    }
}

Connect to server and authenticate the client

Create keypairs and pair your client(application) with BitPay server.
```
php artisan laravel-bitpay:createkeypair
```

What exactly above command do?
- Above command will create Private and Public key, encrypt your private key using bitpay secure storage class using your provided password.
- SIN (Service Identification Number) for your client will be created to uniquely identify requests from your server.
- By using SIN new Token and Pairing Code will be created for your client on bitpay server and will be shown on your console output.
- Token will be used for all future request to bitpay and will automatically be copied to your .env file.
- Based on environment you set TEST/LIVE, command will provide URL to approve your client and you need to copy and search Pairing Code on bitpay server & approve it.
You are all set. ⛳

Examples

Create Invoice and checkout

Let's go step by step.

Create your internal system order and then initiate the workflow by creating bitpay invoice as below,

use Illuminate\Support\Facades\Redirect;
use Vrajroham\LaravelBitpay\LaravelBitpay;

public function createInvoice()
{
    // Create instance of invoice
    $invoice = LaravelBitpay::Invoice();

    // Set item details (Only 1 item)
    $invoice->setItemDesc('Photo');
    $invoice->setItemCode('sku-1');
    $invoice->setPrice(1);

    // Please make sure you provide unique orderid for each invoice
    $invoice->setOrderId(12345); // E.g. Your order number

    // Create Buyer Instance
    $buyer = LaravelBitpay::Buyer();
    $buyer->setName('Vaibhavraj Roham');
    $buyer->setEmail('test@example.me');
    $buyer->setAddress1('Kopargaon');
    $buyer->setNotify(true);

    // Add buyer to invoice
    $invoice->setBuyer($buyer);

    // Set currency
    $invoice->setCurrency('USD');

    // Set redirect url to get back after completing the payment. GET Request
    $invoice->setRedirectURL(route('bitpay-redirect-back'));

    // Optional config. setNotificationUrl()
    // By default, package handles webhooks and dispatches BitpayWebhookReceived event as described above.
    // If you want to handle webhooks your way, you can provide url below. 
    // If handled manually, BitpayWebhookReceived event will not be dispatched.    
    $invoice->setNotificationUrl('Your custom POST route to handle webhooks');

    // Create invoice on bitpay server.
    $invoice = LaravelBitpay::createInvoice($invoice);

    // You can save invoice ID from server, for your your reference
    $invoiceId = $invoice->getId();

    $paymentUrl = $invoice->getUrl();
    // Redirect user to following URL for payment approval.
    return Redirect::to($paymentUrl);
}

Once you get the invoice url for payment, redirect user to that particular url. Use will see something like below on browser.

Next, open your bitpay wallet, scan the code and make a payment. Something like below,

Once payment is done, success screen will be displayed and user needs to click on Return to Shop Name.

Payment done! Now you need to wait for webhook to get notification regarding status of payment.
