Website Payment Pro in Sandbox?

[venera15]

Has anyone been successful in testing the payment pro in sandbox?
I can set up express and works fine, as soon as i install payment pro i get errors, internal errors, time out errors, address not right errors... HELP!

10001 Internal Error - Internal Error
81251 Internal Error - Internal Service Error
(28) Operation timed out with 0 out of -1 bytes received
10001 Internal Error - The transaction could not be loaded


these are just samples of e-mail i got after trying to purchase something with test credit cards supplied from pay pal...

The sandbox is only moderately reliable, and setting up credentials correctly can be confusing at times.

Make it easier on yourself: How about *not* testing in Sandbox, and using real cards, and simply voiding/refunding the transactions?
And if you're having problems, turn on debug log-to-file, and post the logs for analysis.

i started out working in live and just doing capture, not final sale, but i still get an error, it brings me to step 2 again of the check out process, but the transactions shows in paypal???
this is what i got in e-mail
PayPal Direct Payment Error ( <!-- -->)

no numbers?
if i use final sale, will i be able to void the transaction from paypal, or i will be charged from paypal each time?

and i just looked in my orders in admin section in Zen Cart doesn't show as an order nor did i receive confirmation e-mail, so it looks like zen cart didn't register it as a transaction??

will be charged from paypal each time?

If you void an Authorization you will be charged 30 cents by PayPal. What I have been doing is to charge one penny on the authorization and then refund that penny. I send an email to the customer explaining why the charge and refund of one penny. This gets around the 30 cent charge.
