• Setup your merchant information at admin/config/services/unionpay.

• You may call unionpay_submit_form_submit($form, $form_state) with order information: $form_state['values']['amount']: Order amount, in Yuan. $form_state['values']['orderno']: Order Number in your order processing module. $form_state['values']['ordertitle']: Order title, will be shown in Unionpay system. $form_state['values']['ordertime']: Order generation time. The function will produce plain HTML code which will redirect the browser into Unionpay interface website. So there must be an exit() in your caller.

• Your module will need to implement hook_gatewayreponse(array $callback), which will be called when the payment is successful and the result is given to this module. Where $callback looks like: array( 'unionpay' => array( 'orderno' => $_POST['orderNumber'], 'amount' => $_POST['settleAmount']/100, 'transactionno' => $_POST['qid'], 'settledate' => $_POST['settleDate'], 'is_backend' => arg(2)=='response_back', ), );

  For the meaning of qid and settleDate, pelease refer to the manual of unionpay. Please note that result is reliable only if is_backend==TRUE, where the status of the order should be updated in your order process module. when is_backend==FALSE, which means the result should be displayed to the user via frontend.

• The module also provides a query function unionpay_querystatus().
