The PayPal sandbox is a virtual replica of the live PayPal production environment that runs in a self-contained, independent environment. You can start and observe while your applications execute PayPal API requests without disturbing any actual PayPal accounts in the sandbox.
Sandbox Accounts is a service that allows you to create your PayPal sandbox using your existing PayPal accounts. The personal and business credentials you find on the Sandbox > Accounts page in the Developer Dashboard may be used to log into the sandbox as either a buyer (personal) or seller (business).
Create a test account using the following steps: In Sandbox, select Accounts and then Create Account. Select the kind of account and nation you want to test and then click Create. PayPal creates an account for you with fake bank information, credit card information, and balance testing values.
Go to the developer site sandbox accounts page and choose the option for authenticating with the test account’s credentials you wish to link. On the login screen, type in your sandbox account details.
PayPal Sandbox is a simulated testing environment that replicates the PayPal real-world context. It implies it works similarly to creating a genuine Paypal account, but without using actual credit cards or active Paypal accounts. To begin, you must create a PayPal Sandroom Test Account.
