[](#usage)

### Create unified order

[](#create-unified-order)

```
use Omnipay\Omnipay;

$gateway = Omnipay::create( 'WechatPay' );
$gateway->setAppId( 'Your appid here.' );
$gateway->setMchId( 'Your mch_id here.' );
$gateway->setKey( 'Your key for WeChat payment here.' );
$gateway->setTradeType( 'JSAPI' );
$gateway->setAttach( 'test' );
$gateway->setBody( 'test' );
$gateway->setGoodsTag( 'test' );
$gateway->setOutTradeNo( 'Unique order id in your site.' );
$gateway->setTotalFee( 1 );
$gateway->setSpbillCreateIP( Request::ip() );
$gateway->setNotifyUrl( 'http://test.com/pay/notify' );

$response = $gateway->createUnifiedOrder()->send(); // Get prepay_id, code_url etc.

$package = $response->createWebPaymentPackage(); // Get payment parameters for web
```

### Validate notification parameters

[](#validate-notification-parameters)

You can validate parameters as follow:

```
use Omnipay\Omnipay;

$request_content = file_get_contents('php://input');
$gateway = Omnipay::create( 'WechatPay' );
$gateway->setKey( 'Your key for WeChat payment here.' );

$complete_request = $gateway->completeOrder( $request_content );  // Auto convert xml string to array

$complete_response = $complete_request->send();
$complete_response->isResultSuccessful();
$complete_response->isResponseSuccessful();

/**
 * Would get xml string followed while function 'isResultSuccessful' return Boolean true:
 *
 * Or string followed while false
 *
 */
$complete_response->getResponseText();
```

Or use it as follow. But example above is recommended.

```
use Omnipay\Omnipay;

$request_content = file_get_contents('php://input');
$request_params = json_decode(json_encode(simplexml_load_string($request->getContent(), 'SimpleXMLElement', LIBXML_NOCDATA)), true);

$gateway = Omnipay::create( 'WechatPay' );
$gateway->setKey( 'Your key for WeChat payment here.' );

$complete_request = $gateway->completeOrder(array(
  'request_params' => $request_params
));

$complete_response = $complete_request->send();
$complete_response->isResultSuccessful();
$complete_response->isResponseSuccessful();
$complete_response->getResponseText();
```

$gateway = Omnipay::create( 'WechatPay' );
$gateway->setAppId( 'Your appid here.' );
$gateway->setMchId( 'Your mch_id here.' );
$gateway->setKey( 'Your key for WeChat payment here.' );
$request = $gateway->queryOrder([
    'transaction_id'   => 'Transaction id created by wechat'
]);
