Dear Tech Support!

I am creating a demo php Laravel Shop with ECPay integration.

My Project were testing on local computer.

Everything was OK, but I couldn’t test futher because ECPay banned out.

I used this test ECPAYdata from here:

Test Information: https://developers.ecpay.com.tw/?p=16447

MerchantTradeNO !:

This is because you have been using the same MerchantTradeNO. Every time, when creating a new order, please use a new MerchantTradeNO, not a repeated one.
