Test your integration

To complete an end-to-end test of your REST Express Checkout integration, create both merchant and buyer accounts in the PayPal sandbox environment.

Create the accounts, as follows:

Account Details
Merchant Select the Business account type and enter an email address and password.
Buyer Select the Personal account type and enter a high PayPal balance, such as 5000.
