Sandbox Testing
Setting Up Test Accounts
9
N OTE: The Login Email is a pseudo-randomized address, based on the address you specified. 
Credit-card and bank-account numbers also are generated randomly.
Verified Account Status
By default, a test account has a confirmed bank account and email addresses. To create an 
unverified account, change the bank account to unconfirmed. 
Adding a Funding Source
To test transactions, you must add a source of funds to your buyer test account. The following 
sections describe your choices.
1. “Changing or Adding Additional Bank Accounts” on page 115. You can add bank 
accounts, but they will not contain funds unless you use Send Money to send the money to 
the bank-account holder.
2. “Adding Credit Cards ” on page 117. For testing, this is the most efficient way to add 
funds.
N OTE: No money or funds are transferred in the Sandbox; however, to protect confidentiality, 
do not use actual credit-card numbers or bank accounts if you allow other people to log 
in to your Sandbox account. 
Changing or Adding Additional Bank Accounts
 You add a bank account to the Sandbox test account representing a customer or buyer so you 
can test transactions between the buyer’s account and another account; typically, the other 
account is a business account that represents yourself as a merchant. Adding a bank account 
also changes the account status from “Unverified” to “Verified.”
