Most of my clients require donation and shopping cart integration into their websites. I have always used PayPal to run the transactions, but PayPal is a nightmare to work with. I'm looking for an alternative company to handle the credit card processing.
I had looked into Amazon FPS, then realized that it requires an Amazon account in order to process the transaction, which I cannot do. Seems like my only option is Google Checkout. Is it solid? I've read some horror stories of random account closures.
Your thoughts would be helpful as I make this decision. I am looking for ease of API integration, no requirements for the users other than valid credit-card information, and low transaction fees.
