Hi all. I am wondering if anyone can help me resolve this issue.
Basically I am trying to integrate a payment gateway (Toyyibpay from MY). I have followed their documentation to send “userSecretKey” as one of the parameter, but the API returned below error.
Here is my setup
What could be the cause here? I have followed their documentation here : https://toyyibpay.com/apireference
Can anyone point me to the right direction?
