REST APIs
Resource-oriented endpoints, JSON everywhere and consistent error codes.
DevelopersAPI-first platform
Built by engineers,
for engineers
Predictable REST APIs, signed webhooks and SDKs for the stacks you already use. Build and test in a full sandbox, then flip one key to go live.
Webhooks
Signed, retried events for payments, refunds, settlements and KYC.
Idempotency
Safely retry any request without creating duplicate charges.
SDKs & plugins
PHP, Node.js, Python, Java, Android, iOS and major e-commerce platforms.
WebhooksVerify every event
Listen for events, verify the signature, ship.
Every webhook is signed with your secret so you can trust what arrives. Failed deliveries retry with exponential back-off.
- payment.captured · payment.failed
- refund.processed · settlement.completed
- merchant.kyc.approved · payout.sent
$payload = file_get_contents('php://input');
$signature = $_SERVER['HTTP_X_PAYZAZA_SIGNATURE'] ?? '';
$expected = hash_hmac('sha256', $payload, $secret);
if (!hash_equals($expected, $signature)) {
http_response_code(401); exit;
}
$event = json_decode($payload, true);
match ($event['type']) {
'payment.captured' => fulfilOrder($event['data']),
'refund.processed' => markRefunded($event['data']),
default => null,
