Scenario
Server-side notifications(ReturnURL)
When a consumer makes a payment, merchant’s server (i.e. ReturnURL) will receive a notification sent by ECPay’s. When your server receives ECPay’s notification, please respond a string 1|OK.
- Step1. ECPay’s server:send payment notification to ReturnURL.
- Step2. Merchant’s server: respond a string 1|OK.
Special note:
- Barcode payment notification will be sent 2 days later since the payment completes (D+2).
- For non-instant payment (i.e. ATM, CVS or BARCODE), merchants can test if ReturnURL can receive ECPay’s notification on ECPay’s dashboard. ECPay’s dashboard has a function of a mock payment button to test it.
- For common errors of not receiving notifications please see the FAQ.
- The string 1|OK is merely a message in response to tell ECPay’s server that the ReturnURL already successfully received the notification request; the 1|OK will not change the payment state.
