How to develop app for Facebook Pages?

I want to develop a customized shopping cart. I ha开发者_Python百科ve tried to install 2 shopping carts on my page.

1. VendorShop
2. Payvment E-Commerce

But these aren't serving my purpose. So i am thinking to develop my own. Could you give me a head start?

My most important question is, is App development for Facebook Pages is different or its the same?

A quick start guide?

basically app dev for fb pages is pretty much the same as std fb app. so, to get started, you can just refer to those community generated tutorials / start guide, or refer to fb docs.

I am sorry that I cannot provide the direct link here (as it seems to me that SO does not like it... I tried to do that before but my answer just get banned and down-graded from moderator). If you want to get community generated tutorials, refer to my profile and you can get the link.
