InfusionSoft API development in PHP


I want to insert a simple sales order in InfusionSoft but I am unable to achieve such a simple task. I tried all the examples available at the Google, even I tried code available at Code Examples - Keap Developer Portal . Where can I find a simple working example code?

All the available example codes are working on creating new Contacts only.

Many Thanks.

So what have you done and what were your results. Starting at the beginning of the process, have you gotten past the authentication process or are you still needing to work that part out?
