I have never used the API, and I have no idea how to start learning. I'm not a serious programmer (basic PHP knowledge), so it might not even be possible for me to leverage the API.
Are there any simple instructions for accomplishing certain tasks or building specific apps that are geared toward know-nothings like me? ;-) It would be nice if I could at least use it for basic things.
We do have the sample PHP file now at http://www.campaignmonitor.com/api/kits so if you have some PHP knowledge that may give you some ideas.
It is not really a beginner level option though I'm afraid.
