Integrating Paypal API in Adobe Flex

问题:

I am writing a Flex project in which I need to communicate with Paypal via their APIs. Really not sure how to start with - this is my first flex/air application.

I won't be using any server side technology (no Java, Php, .NET, Coldfusion) - all of the requests have to come from Flex and the response be sent back directly to the flex application.

Can someone please give me an example or something to start with. Let's say implementation of RefundTransaction API

in Flex.

Is it possible? If not, then what layer do I need to add to the technology stack? Just need some pointers and I will pick it up from there.

Thanks

Definitely check out this article http://www.adobe.com/devnet/flex/articles/flex_paypal.html

Essentially will need to figure this out myself as well. One of the BIG, BIG, BIG (big enough for ya) keys is to NOT include your API key anywhere in the application (or other sensitive info). This is one of the pitfalls with using a JIT language because it's based on a VM it can't be hidden very effectively.
