What payment gateways work well on appengine?

Question

Well, I created some free apps on top of appengine, but now I want to start charging money. My question is:

What is the best way to collect payments from users. Some services (paypal, google checkout, etc.) work better / worse with AppEngine library limitations? Are there any good examples or tutorials to help me learn this?

Answer 1

Also just something to point to an implementation, a simple boolean property on your user object should allow you to easily enable or disable functions in your application, depending on what level your user paid.

Answer 2

You can do it the way you want, in fact - and there is nothing special about App Engine. For example, you can use Google Checkout or Paypal and charge users on any basis.

Answer 3

Checkout http://Spreedly.com or http://Recurly.com . Both are billing solutions for SaaS applications. http based api and easy to use. I use Spreedly.com

Answer 4

If you plan to sell business applications, you can integrate with the Google Apps Marketplace , which uses Google Checkout for billing.
