Hi,
First of all I am charging you more because I have used payumoney payment gateway.
I am familiar with instructions payment gateway. I think that your source code is missing something.
Thus I, ll have to look all the procedure.
I will not charge you untill your job completely satisfy you. I will help you parsing the detail you want and help you display it whereever you want.
Thanks!.
If out of budget then.... Minimum 1500.
