Vend::Payment::EFSNet(3) Interchange EFSNet Support




[charge mode=efsnet param1=value1 param2=value2]


  LWP::UserAgent and Crypt::SSLeay

Only one of these need be present and working.


The Vend::Payment::EFSNet module implements the efsnet() routine for use with Interchange. It is compatible on a call level with the other Interchange payment modules.

To enable this module, place this directive in "interchange.cfg":

    Require module Vend::Payment::EFSNet

This must be in interchange.cfg or a file included from it.

Make sure CreditCardAuto is off (default in Interchange demos).

The mode can be named anything, but the "gateway" parameter must be set to "efsnet". To make it the default payment gateway for all credit card transactions in a specific catalog, you can set in "catalog.cfg":

    Variable   MV_PAYMENT_MODE  efsnet

It uses several of the standard settings from Interchange payment. Any time we speak of a setting, it is obtained either first from the tag/call options, then from an Interchange order Route named for the mode, then finally a default global payment variable, For example, the "id" parameter would be specified by:

    [charge mode=efsnet id=YourEFSNetID]


    Route efsnet id YourEFSNetID


    Variable MV_PAYMENT_ID      YourEFSNetID

The active settings are:

Your EFSNet Store ID, which you can get from the Merchant Services panel after logging in with the username and password supplied to you by Concord when you signed up.

(Check the ``Credentials'' page after login)

Global parameter is MV_PAYMENT_ID.

Your EFSNet Store Key, which you can get from the Merchant Services panel. Global parameter is MV_PAYMENT_SECRET.
The type of transaction to be run. Valid values are:

    Interchange         EFSNet
    ----------------    -----------------
        auth            CreditCardAuthorize
        return          CreditCardRefund
        reverse         CreditCardRefund
        sale            CreditCardCharge
        settle          CreditCardSettle
        void            VoidTransaction
This remaps the form variable names to the ones needed by EFSNet. See the "Payment Settings" heading in the Interchange documentation for use.


Try the instructions above, then switch to the test servers. A test order should complete with this test card number: 4111 1111 1111 1111

Enabling the test servers:


If nothing works:

  • Make sure you ``Require''d the module in interchange.cfg:

        Require module Vend::Payment::EFSNet
  • Make sure either Net::SSLeay or Crypt::SSLeay and LWP::UserAgent are installed and working. You can test to see whether your Perl thinks they are:

        perl -MNet::SSLeay -e 'print "It works\n"'


        perl -MLWP::UserAgent -MCrypt::SSLeay -e 'print "It works\n"'

    If either one prints ``It works.'' and returns to the prompt you should be OK (presuming they are in working order otherwise).

  • Check the error logs, both catalog and global.
  • Make sure you set your payment parameters properly.
  • Try an order, then put this code in a page:

            my $string = $Tag->uneval( { ref => $Session->{payment_result} });
            $string =~ s/{/{\n/;
            $string =~ s/,/,\n/g;
            return $string;

    That should show what happened.

  • If all else fails, consultants are available to help with integration for a fee. See for mailing lists and other information.


CreditCardCredit transactions (where you apply a credit on a card without the transaction ID of a previous charge) are supported by this module, but disabled by default in new EFSNet accounts. If you need to use this function, call EFSNet.

This module supports partial returns, but EFSNet needs to know what the original transaction amount was. You can provide this by passing the value in the original_amount parameter.


Concord EFSNet requires all interface code to be certified by them. If you make a change to this module, please contact EFSNet for re-certification. More information at:


There is actually nothing *in* Vend::Payment::EFSNet. It changes packages to Vend::Payment and places things there.
