This transaction is invalid - Paypal express

[n350zz]

Hi

I have recently started using the latest Zen cart version 1.3.7 and I’m trying to set up the inbuilt Paypal express modal, I have followed the information provided by you guys in Zencart’s help forum and activated the API access in my Paypal Premier account then copied my information and installed it into the option boxes within Zen carts admin area.
I have also emailed my server host and asked him to install cURL into his server obtained his IP address tried cURL Proxy Status on/off with and without the port forwarding but still I am having trouble getting the Paypal express to work.

If I run a test sale on my site it redirects me to “https://www.paypal.com/cgi-bin/websc...ction=continue” But with an error: “This transaction is invalid. Please return to the recipient's website to complete your transaction using their regular checkout flow”

I am wondering if anyone might have any information that could help me find out where the problem is.

Thanks

Please turn on Debug Logging inside your PayPal Express Checkout module settings.
It will be helpful to see the contents of the SetExpressCheckoutTransaction emails that you get from this ...

Where you see a series of XXXXX, these have been blanked out on purpose as they contain personal info, zen id's or server info

Using zen 1.3.7

Any help would be appreciated.

Thanks Ajeh

Funny, did a search specific to paypal express and didn't come accross that thread. sorry about that!!

Anyway

Have applied patch now!!

Now i return to step 1 of checkout with an error stating the following:

An error occurred when we tried to contact the payment processor. Please try again, select an alternate payment method, or contact the store owner for assistance. ()

I then receive 12 debug emails.

Please advise if you would like me to cut and paste the contents of emails

Tryed this twice thus I received another 12 debug email.

TIA

Hi

Same problem after installing the patch 4 me as well, the Paypal payment logo just returns me to http://www.**********.biz/index.php?main_page=login with an error message in a red box saying: An error occurred when we tried to contact the payment processor. Please try again, select an alternate payment method, or contact the store owner for assistance. ()

I have gone through the Debug emails of mine... from what I can tell I have a problem that pops up and its


Response: array (
'ACK' => 'Failure',
'L_ERRORCODE0' => '81210',
'L_SHORTMESSAGE0' => 'Invalid Parameter',
'L_LONGMESSAGE0' => 'Country : Invalid Parameter',
'L_SEVERITYCODE0' => 'Error',
)


Now I am not sure what that means... anyone know?

[Jeff_Mash]

I too am getting customers complaining of this same error message:

An error occurred when we tried to contact the payment processor. Please try again, select an alternate payment method, or contact the store owner for assistance. ()

Doesn't happen with everyone, but enough to drive me crazy throughout the day with complaints.

I too have already applied the aforementioned patch. I just turned on the debug mode so I will post the emails as they come in.
