Quick start

use OxaPay\Laravel\Support\Facades\OxaPay;

// via facade
$res = OxaPay::payment()->generateInvoice([
    'amount' => 10.5,
    'currency' => 'USDT'
]);

// via helper
$res = oxapay()->payment()->generateInvoice([ 
    'amount' => 10.5,
    'currency' => 'USDT'
]);

// key is optional and use default key from config if no passed
$res = OxaPay::payment('key_2')->generateInvoice([
    'amount' => 10.5,
    'currency' => 'USDT'
]);

// or use raw key
$res = OxaPay::payment("XXXXXX-XXXXXX-XXXXXX-XXXXXX")->generateInvoice([
    'amount' => 10.5,
    'currency' => 'USDT'
]);

Handling Webhooks (Payments & Payouts)

use OxaPay\Laravel\Support\Facades\OxaPay;

try{
    $res = OxaPay::webhook()->getData();
    // ...
}catch (WebhookSignatureException $e) {
    // ...
}

// or you can get data without verify HMAC
$res = OxaPay::webhook()->getData(false);
