Scenario

When a payment is completed, ECPay can also return and redirect the payment result to the OrderResultURL, which is a webpage set by merchants when creating order (sending API request to /GetTokenbyTrade.)
- Step1. ECPay: redirect the payment result to OrderResultURL.
- Step2. Merchant’s webpage (OrderResultURL): receives the notification.
Special note:
- Be sure to check and determine which page to be displayed based on the status in notifications.
- Since the authorization time varies from banks, if you does not receive the notifications, please call the API (searching order API) to query the order state.
- Please use HTTPS, otherwise some browsers may pop up alert message.
