Payflow Pro (PayPal) Authentication Errors

Recommended Posts

Hey everyone, we're in the process of setting up our WHMCS server. We are having issues using the Payflow Pro (PayPal) gateway. At the end of September, the gateway was working in test mode fine. Now we cannot use the gateway in test mode or live mode, and we're constantly getting the gateway error (from the log):

 

RESULT => 1

RESPMSG => User authentication failed

 

I know the information in the Payflow Pro gateway module is correct, as we are using the same info on another portion of our website. Also, additional tests of using the PayPal API from a script on the web server is returning results in test mode and live mode (test mode is generating successful results, live mode is generating bad credit card numbers, all working). There seems to be some issue of using WHMCS->Payflow. Additionally, we have no IP restriction setup in our Payflow manager.

 

Anyone else experiencing this or can point me in the right direction?

I figured out the issue. The Payflow Pro gateway does not like the use of special characters in the password. I removed them and used strictly alpha numeric and all is well.

 

Thanks for the info that help me a lot, whmcs.com do not say anything about special characters in their documentation.

Now my question is, do you have any problem using the USE EXIST CARD option?

 

when I select that option I see the last 4 digits of my credit card and ask me for my cvv number so I enter the cvv number and I click continue but I get an error.

 

>>>>>The credit card details you entered were declined. Please try a different card or contact support.

 

I am sure the cvv number is correct, then I have to re-enter all credit card info manually and the system accept the card info. is just when I select the USE EXIST CARD option.

 

I contact WHMCS they told me that I need to contact paypal to activate the reference transactions so I did that but I continue with the same problem, paypal told me that the problem is that whmcs is not sending the correct information when I select USE EXIST CARD option. so paypal told me to ask whmcs developers to call them to find out the problem, I did that but looks like whmcs developer dont want to call paypal.

 

Any one have this problem?
