# Vend::Payment::EFSNet(3pm)

Interchange EFSNet Support

## NAME

Vend::Payment::EFSNet - Interchange EFSNet Support

## SYNOPSIS

```
    &charge=efsnet

        or

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

## PREREQUISITES

```
  Net::SSLeay

    or

  LWP::UserAgent and Crypt::SSLeay
```

Only one of these need be present and working.

## DESCRIPTION

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]
```

or

```
    Route efsnet id YourEFSNetID
```

or

```
    Variable MV_PAYMENT_ID      YourEFSNetID
```

The active settings are:

- id

  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.

  http://www.concordefsnet.com/Developers/MerchantLogin.asp

  (Check the "Credentials" page after login)

  Global parameter is MV\_PAYMENT\_ID.

- secret

  Your EFSNet Store Key, which you can get from the Merchant Services panel. Global parameter is MV\_PAYMENT\_SECRET.

- transaction

  The type of transaction to be run. Valid values are:

  ```
      Interchange         EFSNet
      ----------------    -----------------
          auth            CreditCardAuthorize
          return          CreditCardRefund
          reverse         CreditCardRefund
          sale            CreditCardCharge
          settle          CreditCardSettle
          void            VoidTransaction
  ```

- remap

  This remaps the form variable names to the ones needed by EFSNet. See the `"Payment Settings"` heading in the Interchange documentation for use.

### Troubleshooting

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:

MV\_PAYMENT\_HOST testefsnet.concordebiz.com

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"'
  ```

  or

  ```
      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:

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

  That should show what happened.

  If all else fails, consultants are available to help with integration for a fee. See http://www.icdevgroup.org/ for mailing lists and other information.

## NOTES

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.

## CHANGES

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: http://www.concordefsnet.com/Developers/Documentation.asp

## BUGS

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