1. Go to https://developer.paypal.com 2. Log in with your REAL Account (NOT the Sandbox account) 3. Click on "Accounts" in left hand menu 4. Find "To link your sandbox account to your developer account, log in to PayPal..." click on that "log in to PayPal" link 5. Provide your SANDBOX account credentials to log in. This will link your SANDBOX account with your Developer account. 6. Go back to developer.paypal.com / Accounts. See your sandbox account in the list. 7. Click on the arrow to the left of your Sandbox account. This will show you the sub-menu related to that Sandbox account. 8. Click on "Notifications" link. You will see all mail that was "sent" to the Sandbox account. Clicking on any mail will open it as a Preview. 9. There may be one more disappointment. Even though you can Preview the mail, it could be that you do not see the confirmation link to click within that email. To fix that: 10. Click on "Notifications" in the left hand menu 11. Click "Search notifications". Select your Sandbox account / specify date range. Click "Search" 12. Open found emails. The preview of these will be better, and the links should be there. Enjoy the mess!
