Accept crypto payments in PHP

Add non-custodial crypto checkout to your PHP app: create an invoice, send the buyer to the hosted checkout, and fulfill on a signed webhook. Funds settle straight to your own wallet, $0 platform fees.

Install

composer require shieldz/shieldz

Create an invoice and redirect to checkout

use Shieldz\Shieldz;
$shieldz = new Shieldz(getenv('SHIELDZ_API_KEY'));
$invoice = $shieldz->invoices->create(['amount_usd_cents' => 5000, 'memo' => 'Order']);
header('Location: ' . $invoice['pay_url']);

Verify the webhook

use Shieldz\Webhooks;
$event = Webhooks::constructEvent(
    file_get_contents('php://input'),
    $_SERVER['HTTP_X_SHIELDZ_SIGNATURE'] ?? '',
    getenv('SHIELDZ_WEBHOOK_SECRET')
);
if ($event['type'] === 'invoice.paid') { /* fulfill the order */ }
