Coinbase Commerce

To integrate Coinbase Commerce as a payment method in a Laravel app, you can follow these steps:

Create a Coinbase Commerce account and generate an API key.
Install the Coinbase Commerce PHP SDK in your Laravel application using Composer.

bash
composer require coinbase/coinbase-commerce

Add the Coinbase Commerce API key to your Laravel app's .env file as COINBASE_COMMERCE_API_KEY.
Create a new controller to handle Coinbase Commerce payments. For example, you could create a CoinbaseController with methods for creating and handling payments.
In the CoinbaseController, use the Coinbase Commerce SDK to create a new payment:

use CoinbaseCommerce\ApiClient;
use CoinbaseCommerce\Resources\Charge;

class CoinbaseController extends Controller
{
    public function createPayment(Request $request)
    {
        $apiClient = new ApiClient();
        $apiClient->setApiKey(env('COINBASE_COMMERCE_API_KEY'));

        $chargeData = [
            'name' => 'My Product',
            'description' => 'My Product Description',
            'local_price' => [
                'amount' => '10.00',
                'currency' => 'USD',
            ],
            'pricing_type' => 'fixed_price',
            'metadata' => [
                'customer_id' => '123',
            ],
        ];

        $charge = Charge::create($chargeData, $apiClient);
        return view('payments.coinbase', ['charge' => $charge]);
    }
}


This code creates a new Charge object using the Coinbase Commerce API, sets the name, description, local_price, pricing_type, and metadata fields, and returns the Charge object to a view.

Create a new view for the payment form. In this example, we'll create a coinbase.blade.php view:

<!DOCTYPE html>
<html>
    <head>
        <title>Pay with Coinbase Commerce</title>
    </head>
    <body>
        <h1>Pay with Coinbase Commerce</h1>
        <form action="{{ route('coinbase.pay') }}" method="POST">
            @csrf
            <script src="https://commerce.coinbase.com/v1/checkout.js?c={{ $charge->code }}"></script>
            <button type="submit">Pay with Coinbase Commerce</button>
        </form>
    </body>
</html>


This code includes the Coinbase Commerce checkout script and a form to submit the payment.

Create a new route in your Laravel app to handle the payment form submission:

css
Route::post('/coinbase/pay', [CoinbaseController::class, 'handlePayment'])->name('coinbase.pay');


In the CoinbaseController, create a new method to handle the payment submission:

php
class CoinbaseController extends Controller
{
    public function handlePayment(Request $request)
    {
        $chargeCode = $request->input('code');

        $apiClient = new ApiClient();
        $apiClient->setApiKey(env('COINBASE_COMMERCE_API_KEY'));

        $charge = Charge::retrieve($chargeCode, $apiClient);

        if ($charge->timeline[0]->status === 'COMPLETED') {
            return view('payments.success', ['charge' => $charge]);
        } else {
            return view('payments.failure', ['charge' => $charge]);
        }
    }
}

This code retrieves the Charge object using the Coinbase Commerce API and checks if the payment was completed successfully. If the payment was successful, it returns a success view; otherwise, it returns a failure view.
