Verisign PayFlow Pro Payment Gateway Integration

Previous  Top  Next

PayFlow Pro is a backend payment processing method. The payment form is generated by the AShop script orderform.php. SSL support is required.

Setup
1.   To integrate AShop Deluxe with the PayFlow Pro gateway, PayFlow Pro client software must be installed on the server. It is available on the Downloads page of Verisign Manager. Installation instructions are included with the client software.

Note: The PayFlow Pro software only needs to be installed once on the server. It is already installed on AShopWebHosting.com servers and is available to all hosted domains. The only thing that is needed to make it work for a new site on our server is to add the certs directory with its contents.

2.   Put the f73e89fd.0 file (included with the client software) in the certs subdirectory of the directory where you installed AShop.

Test Mode
Credit Card Numbers For Testing
Visa: 4111111111111111
MasterCard: 5555555555554444
American Express: 378282246310005

The AShop payment option AND the Verisign account must be in test mode in order for these test numbers to work. Besides activating test mode in the Verisign account, you must also deactivate all security filters in the VeriSign Manager to make test mode work. The filters will cause all transactions to be declined since test mode doesn't support them.

To set test mode in the Verisign account...

1.	Login to the Verisign Manager and go to the Security page

2.	Click Test Setup

3.	Click Edit Filters

4.	Deactivate all the filters and click Continue

5.	Click Continue once more

6.	Click Deploy Test Mode and finally click Finish.

Troubleshooting

It is very easy to confuse the settings between Verisign and AShop. If everything seems right, but the credit cards are denied, double check the payment option settings within AShop.

The Merchant ID setting within AShop is the Verisign Username.
The Security Secret setting within AShop is the password for the Verisign merchant account login.
