Understand the Sandbox and Production environments

As a member of the eBay Developers Program, you’ll work in two environments:

Sandbox	A self-contained virtual testing environment that allows you to test your application without using real eBay users, real eBay listings, or real money. As you develop your application, you’ll need to test its functionality in the Sandbox by simulating the various tasks related to buying and selling on eBay before you transact in the Production environment. Items listed and sold in the Sandbox aren’t real transactions, and all listing fees and item purchases are paid with fictional money.
Production	The live environment where an eBay-enabled application sends real data to the eBay marketplace with real eBay users, listings, and transactions. An eBay user who views the eBay marketplace through a browser or the eBay mobile application is viewing data in the Production environment. Your application will run in this environment after you go live.
