Examples

Account Info

$res = $client->accountInfo("cashpay");
print_r($res);

Create Order

$res = $client->createOrder([
    "payment_name"=>"cashpay",
    "currency_id"=>"USD",
    "payerPhone"=>"967770000000",
    "payerEmail"=>"buyer@example.com",
    "beneficiaryList"=>[
        ["amount"=>100,"itemName"=>"ساعة","quantity"=>2]
    ],
    "des"=>"شراء ساعة"
]);
print_r($res);

Check Order

$res = $client->checkOrder([
    "payment_name"=>"cashpay",
    "payerPhone"=>"967770000000",
    "payerEmail"=>"buyer@example.com",
    "requestIdRes"=>"66ae540d9736d",
    "orderID"=>"order.pay-379-5825"
]);
print_r($res);

Invoice List

$res = $client->invoiceList("cashpay","buyer@example.com");
print_r($res);

Payload Validation & Proxy Handler

Internal Order Validation (OrderValidator) You can use OrderValidator to check payload integrity before sending requests:

use OnePay\Validation\OrderValidator;

$payload = [ ... ]; // order payload

if (!OrderValidator::validateCreateOrder($payload, $errors)) {
    print_r($errors); // Array of validation errors
}

Proxy Router Example (proxy_router.php)

The SDK includes a ready-to-run REST Proxy located in examples/proxy_router.php. It automatically maps incoming HTTP requests to ApiHandler and handles validation out of the box.
