Paypal Sandbox

Hi, I am trying to test my site with Paypal Sandbox. I have read some of the previous posts, but can't seem to get it right. I went to paypal sandbox and created an account. I setup some test accounts, so I have two emails that are "personal" and one that is "business".

Now, when I go to the opencart admin, which email do I put in there, and when I try to "checkout" which email do I use? Thank you.

Sandbox is for testing. Create a Paypal Sandbox account first; when you get into that, create a seller account and a buyer account..... these are both fake, of course, but you can see all the transaction details on paypal without actually risking losing any money.

In the Paypal module, put in the fake seller's email address.
When you go to test the checkout, put in the fake buyer's email address.

This is NOT the same address that you signed up for Sandbox with; Once you get both buyer/seller set up on Sandbox, Paypal will display both accounts with the email addresses to use (they're not the same ones you type in when creating the accounts!)
Hope this helps.

Thank you very much. I got it working.
