i already have Nigeria interswitch webpay payment module installed on my opencart shopping website but its not working well because they have changed their connection parameters. all i need is someone who can go through the payment module and modify accordingly to make it work.
You must have done a similar web payment integration in nigeria.
Send a link to similar integration you have done to me.
Just the payment module integration
If you are not a payment gateway expert with proof, dont bid.
if your billing is high, dont bid.
if you do not understand the opencart website programming, dont bid
if estimated day of completion is more than 3 days, dont bid.
if you already have done webpay interswitch for any nigerian shopping cart before, its a plus.
