New Features

FeatureDescription
Free Tier AWS has announced a pricing change that gives you a free amount of data transfer out each month. For each region, the first 1 GB of data transfer out each month is free of charge. This pricing change goes into effect on April 1, 2010.

This new free tier affects the amount AWS charges you to cover the AWS costs of your customers; the amount your customers pay you doesn't change.

You get the benefit of this free tier for each of your DevPay products. The free tier works the same as other AWS tiered pricing (e.g., tiered storage charges for Amazon S3). DevPay applies the tiered discount rates to the total usage across all the customers of a given DevPay product. So for example, let's say customer A uses 0.7 GB during the month, and customer B uses 1 GB. AWS applies the free tier to the total usage amount across both customers (1.7 GB), and not to each customer separately. So in this case you pay the costs for 0.7 GB data transfer out.

For more information about how DevPay handles tiered costs, go to The Cost of AWS Services > The Cost of Tiered Usage Types in the Amazon DevPay Developer Guide.

Known Issues

IssueDescription
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 http://www.amazon.com/dp-applications).
  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 https://ls.amazonaws.com/doc/2008-04-28/AmazonLS.wsdl) 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.
