Developing and Deploying PayPal Apps
How would you like to be able to get more traffic for your PayPal-based applications? Embed your apps in the PayPal.com site? Have thousands or even millions of customers consider and potentially use your new application?
If that sounds like a great opportunity to you, you need to look closely at PayPal Apps. PayPal Apps allows you to develop a lightweight, web standards based “gadget” that will embed your application functionality into PayPal’s site on a new PayPal Apps tray, making it available to the masses of PayPal account owners.
Intrigued? Good! Let’s dive into the details so you can start developing and deploying a PayPal App of your own.
What is PayPal Apps?
PayPal Apps are built by developers, tested in the PayPal Sandbox, and submitted to PayPal for review and approval. If approved, they are made available via a PayPal Apps tray on the live PayPal.com site. From there, they will be visible to millions of PayPal customers. Build the right App, and you could see tremendous traffic in short order!
You can read more about what PayPal Apps are and aren’t, as well as things to note as you begin Apps development, via the excellent “Developing a PayPal App” technical overview page.
As I wrote in a recent DevZone blog post, PayPal Apps were launched at Innovate 2010 to much fanfare. There was a good introductory session given on Apps, “PayPal Apps: The Future Starts Here“, and it is worth watching to familiarize yourself with the technology and its use:
You should also read through PayPal Technology Evangelist Rasesh Shah‘s series of blog posts on PayPal Apps. The first installment does a good job of defining Apps and how to get started with them. Read any or all of his four installments by clicking on each of them here: “Getting Started With PayPal Apps“, “Building Your First Hello World PayPal App“, “Making payments from a PayPal App (Gadget)“, and “Building an advanced PayPal App“. And remember his “HelloWorld” example in particular, as we’ll refer to it again later.
If you cut PayPal Apps, it bleeds OpenSocial
If you decide to try your hand at PayPal Apps development, you will want to dig a little deeper under the covers. PayPal wisely chose to build Apps on top of the OpenSocial gadget framework. OpenSocial originally spun out of the Google Gadgets framework as an attempt to guarantee an open alternative to the proprietary Facebook Platform for social application development. By embracing this open model, PayPal has guaranteed maximum transferability of skills and availability of tools with minimum overhead. Very smart.
