We (meaning myself and my computer tech) cannot figure out the USPS API codes. He does not know where to put the API codes into the OpenCart coding. Can anyone help with this? Here is what he said to me in the last email about this issue:
I am using OpenCart version 1.3.4 and using the supplied United States Postal Service Shipping Module.As far as USPS/OpenCart, I need the location of where to put the API codes in the OpenCart code. I have the API codes, but no idea where they are supposed to go.
Please advise and help in anyway possible, thank you
