capture and emulate internet data

I have seen a technique that involves API modification. If you know which API it uses to connect to the server and retrieve the information and know exactly what and how the data is returned, you can first use VirtualProtect to make the API readable and writable, patch it to call your own custom code, feed in the correct return values, and then restore the original code to the API in case it is used for another function in the program.
