Integration with PayPhrase also requires us to integrate with Amazon Payments. At this time we are not planing to add integration with Amazon Payments. This is because adding in a payment processor is one of the most complex task our development team can undertake and so is selecting the best possible payment processor to add if we do. Amazon Payments, only offers limited access to users outside the United States. We have a large number of users, in other parts of North America, Europe and other parts of the world.
