Amazon has released an Appstore Sales Reporting API that allows developers to download sales reports programmatically. Developers use the API to retrieve monthly sales data as compressed CSV files. The CSV file contains item information such as marketplace, invoice ID, item name, and sales price.
The Google Drive API makes it possible for developers to add Google Drive file access to their own apps. Well, Google plans to retire the Google Drive Android API next year and replace it with the Google Drive REST API. Get ready to migrate your apps before December 6, 2019.
