I read your blog on the node.js POST data. Recently I came across a problem where I even though using the body-parser middleware, I am unable to read the POST data sent to my webhook (built on node.js). I would appreciate if you can take a look at it and let me know what I am doing wrong. I opened an issue on the body-parser module git : https://github.com/expressjs/body-parser/issues/213
