Launch Sandbox.
2. Open the HTML file containing the Buy Now Button.
3. Click the Buy Now Button.
4. Log in using your test buyer account.
5. Follow the on-screen instructions to complete your test payment.
Verifying a Test Payment
1. Log in to Developer Central.
2. Click the Email tab.
Your Sandbox inbox shows payment confirmation email messages for the seller and buyer.
3. To further verify that the payment was successful:
– Check your web server for IPN notifications related to the payment.
– Launch the Sandbox as your test buyer or seller account and navigate to My Account >
Overview to see the transaction in your Recent Activity.
