Sandbox Testing
Accessing the PayPal Sandbox
9
Accessing the PayPal Sandbox
To access the PayPal Sandbox, sign up for an account at https://developer.paypal.com. After 
signing up, you access the Sandbox programatically or by logging in.
Depending on the PayPal feature you want to test with an application, you need to set up 
different types of test accounts: PayPal Personal (or Premier) and Business accounts. See 
“Planning the Types of Test Accounts You Need” on page 111.
Digital 
certificates
After you request digital certificates for use with the 
PayPal Web Services API, the Sandbox 
automatically generates them. They are available for 
immediate downloading.
To safeguard your and your customers’ 
security, requests for digital certificates for 
use with the Live PayPal Web Services 
API must be verified by PayPal before 
they are issued. You are notified in email 
when your request is approved.
