Transaction Failed with PayPal payments pro

I am working on two shopping carts simultaneously and both are returning Transaction Failed on checkout_failure.cfm. I'm looking at the server bindings, but I can't see any way to attach error messages to the Transaction Failed statement. It's bizarre that it's happening to both carts. How can I find out why they are failing?

You should be able to add error messages to the page through the bindings interface in dreamweaver.

Go to the bindings tab and click the plus button. Then choose eCart->Checkout->Local checkout results.

Then choose the error result you would like to see more information about... it appears you are using paypal direct pay transaction, so choose that one and click ok.

Then you will be able to drag and drop more information about why the failure occurred such as an error message.

Thanks, Ray. Worked like a charm! Come to find out, you can't enter United States as a value in the country field. You have to use US. :P

Found one of your other posts and added the error message bindings to the page, and I can now see that the error is as follows:

Your transaction could not be completed.

Failure

10002

Security error

Security error

Security header is not valid

This error means your username, password, or security key is invalid.

I am having the same problem...
All was working well with sandbox.
I am now using the "live" credentials NOT sand box username, password and signature.
I have triple checked in checkout.php and confirm.php.
Is it anywhere else?
Where all does this need to be changed?
What files?
Thanks in advance...

PP_confirm is also used for express checkout. Are you getting the error when using the paypal express checkout button or the direct payment form?

There is only one place for the direct payment form the information appears and that is on the confirm page in the local checkout server behavior.

There are three places for express checkout. One on the checkout page and if it isn't corrected you won't ever get to the paypal site, and two on the pp_confirm page. One to get the user data from paypal and the second to confirm the order.

Depending on where in the process you are running into the error you should be able to find where the code needs to be updated.

Hi Ray,
Thanks...
I am using direct payment.
I removed the express payment link from the checkout page.
I get to the checkout_failure.php page with the 10002 Security header is not valid.

Any ideas?

That means your information your username, passoword or security key is incorrect on the confirm page.
