Any1 to direct to me a Writing API For Dummies pdf

Me too would like to get some blogs, videos or other sources for information about good interface and API design.
I often write interfaces, small libs, and modules and would love to be able to skip some iterations...

I get to use my joke!
APIs are like one night stands; they are really fun but when you screw up you support it for 18 years.

@M1sf3t let's go with Rest

As I am developing a web chat app I want to develop a android app at some point instead of making it responsive

So I want an API that will pass information to and from android app

The easiest one to go with

If it’s about ReST, see swagger.io
