New Features

Amazon S3 Reduced Redundancy Storage

On May 18, 2010, Amazon S3 announced Reduced Redundancy Storage, which is a new storage option that enables customers to reduce their costs by storing non-critical, reproducible data at lower levels of redundancy. For more information about the feature, go to the Amazon S3 product page.

Your existing Amazon S3 applications are not affected by this release. They will continue to operate as they have. If you want to expand your application to use the new Amazon S3 feature:

  • Update your application to support Reduced Redundancy Storage (for information about using the feature, refer to the Amazon S3 documentation)

  • Update your product's price to include prices for the new usage types related to Reduced Redundancy Storage (for more information, go to Changing Pricing) in the Amazon DevPay Developer Guide

  • Make the newly updated application available to customers only after your price change has taken effect; this ensures you get paid for your customers' use of the new Amazon S3 feature

Known Issues

Failure of Sign-Up Payment If your product has a sign-up/monthly fee, and the customer's sign-up payment fails because the payment method isn't valid, the customer is not officially subscribed to your product. This can be verified with VerifyProductSubscriptionByTokens (for desktop products) or VerifyProductSubscriptionByPid (for hosted products), which returns a value of "false". The customer can't use the product, even if you've activated the customer. We recommend your product poll the customer's subscription status after activating the customer. If the status is still "false" 15 minutes after activation, then the product should display a special message when the customer tries to use the product the first time. The message should tell the customer to:
  1. Cancel the subscription by going to the Application Billing page (at
  2. Update the payment method (also at the Application Billing page).
  3. Resubscribe to the product with the valid payment method (by clicking the purchase URL).
Error in WSDL The License Service WSDL (at incorrectly lists a child element called RequestId in the ErrorResponse element. The correct name of the element is RequestID (with a capital D). Our plan is to update the WSDL to match what the service actually returns (RequestID).
Limitation on AWS services used You can build an application that monetizes Amazon EC2 or Amazon Simple Storage Service, but not both.
Throttling of License Service requests per developer Requests to the License Service are throttled as necessary. They are throttled per developer instead of per DevPay product. Therefore, if you have multiple DevPay products, the sum of the requests from all your DevPay products is used to determine whether your requests need to be throttled.
Information not available on the first of the month If you visit your DevPay Activity page on the first of the month, your revenue statement for the previous month might not yet be available. We instead recommend that you view the page after you've received the e-mail from AWS that indicates the revenue statement is available.

Also, the page might display zeros for all the values because the page has not yet been updated with the information for the first day of the month. If this happens, we recommend that you return to the page on the second day of the month.
Withdrawal limit When you withdraw money from your Amazon Payments account, the withdrawal amount must be at least $10.00.
