Can not pay in paypal sandbox using a test Test Account

Question

Since paypal updated their sandbox, I encounter a lot of problems. I can not simulate a payment using sandbox. Whenever i use an "old test account", created before the update, this error message comes out

This Sandbox email address is not available. Please enter another email address.

I have created a new account and unfortunately it also doesn't work. Same error message comes out. Below is the details that inputted to create an account.

1. email: "[email protected]"
2. payment bal. : 5000
3. bank verified: yes
4. paymentcard: paypal
5. credit card type: none

Can anyone tell how to do payment simulation using the new paypal sandbox? I have read all the documenation in x.com, None of them worked. The links redirects me to developers.paypal.com and prompt me to login again and again.

Answer 1

I resolved it by:

• loggin out of test site
• clearing browser cache and cookies (I use chrome).
• Logging back into the test site
• Changing the credentials for the submission to the automatically created business account in the new paypal sandbox
• Submitting.

Works as expected now.

Answer 2

The simplest solution is to use an incognito browser window for the test customer.

This separates the cookies for the "customer" from the cookies for the "merchant" and the cookies from your real PayPal account, which seems to cause the problem.

Ctrl-Shift-N in Chrome.
