Despite how you may feel as a developer towards Facebook, you have to admit they work fast. The company is always putting out new APIs and updates to existing APIs that make the platform a better place to develop on. The newest update should help developers get constant updates on how well their app is doing.
The newest feature to join the Facebook family is called the Payments Reporting API. Developers will now be able to download "daily reports of transaction data."

If that sounds good to you, you can get to using the new API right away. It will replace the current email system for now, but Facebook expects everybody to switch to the API within the next 90s days. Afterwards, Facebook will no longer send payment reports via email.
