Prerequisites for PayPal Test Payments
We don't offer specific test data for PayPal. Instead, you'll have to create your own PayPal Sandbox (Buyer-)Account.
Follow this procedure to initiate a test payment:
Register at https://developer.paypal.com/ for a "Sandbox Test Environment" additionally to your PayPal business account. Alternatively, you can create an account at sandbox.paypal.com
After you registered successfully you may create a new test account (buyer) within your "sandbox". This buyer test account will be used for your test payment.
Ensure you are logged into your "Sandbox Test Environment" before initiating a test payment.
Then initiate a payment transaction using your E-Commerce application (e.g. your shop). Please pay attention to use value "test" for parameter "mode" (mode=test). Use the buyer test account credentials as a customer in your webshop to start payment.

If you want to make End-to-End Tests with PayPal, you'll also need a Sandbox Merchant Account. Please contact our Merchant Service so we can store the Sandbox Merchant Account in your PAYONE Account.
