OAuth is an often confusing protocol, that can be very difficult to get started with and nigh-on impossible to debug.
With that in mind, I set out to learn more about OAuth, why it’s there, how it works, and what you can do with it.
Of course the best way to do this is to actually get developing. So I got my PHP out, fired up my favourite IDE, and got started.
Here’s what I learnt, from the beginning, and it will hopefully save anyone else getting started with OAuth a bit of time and a lot of confusion.
