Hello @AliMAli
Thank you for posting to the PayPal Sandbox Community.
The PayPal sandbox is a self-contained, virtual testing environment that simulates the live PayPal production environment.
When you initiate a transaction through a sandbox account, PayPal creates a mock transaction that behaves exactly like a transaction in the live environment. By using fictitious sandbox accounts with their associated authentication credentials in your PayPal API calls, you can test and debug your apps without referencing any real PayPal users or live PayPal accounts.
What that means is that Sandbox has virtual funds that cannot be transferred to a PayPal Live Account. No live payment processing takes place in Sandbox, as it is a simulation to allow testing.
Thank you,
Jennifer
