SYNOPSIS

&charge=echo

    or

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

PREREQUISITES

If you have not done so already, you will need to sign up for an ECHO
account. You will be provided an ID and a PIN (also known as
'secret'). You may also sign up for a test account at the following
URL:

http://www.echo-inc.com/echotestapp.php

This subroutine uses the OpenECHO module. Make sure OpenECHO.pm is in your @INC array. It is available for download, see the following URLs:

http://www.openecho.com/
http://www.echo-inc.com/

The OpenECHO.pm module itself has some additional prerequisites:

Net::SSLeay

or

LWP::UserAgent and Crypt::SSLeay

Only one of these need be present and working. Net::SSLeay is
preferred as some have reported problems using LWP::UserAgent and
Crypt::SSLeay.

URL::Escape

This module is used to write some of the URLs used by the OpenECHO
module. It is recommended that you read the documention for the
OpenECHO module itself in addition to this document.

DESCRIPTION

The Vend::Payment::ECHO module implements the echo() 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::ECHO

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

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

The mode can be named anything, but the "gateway" parameter must be set to "echo". 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 echo

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:

Route echo id Your_ECHO_ID

or (with only ECHO as a payment provider)

Variable MV_PAYMENT_ID Your_ECHO_ID

or

Variable ECHO_PAYMENT_ID Your_ECHO_ID

or

[charge mode=echo id=Your_ECHO_ID]

The active settings are:

id Your account ID, supplied by ECHO when you sign up. Global

parameter is MV_PAYMENT_ID or ECHO_PAYMENT_ID.

secret

Your account password, selected by you or provided by ECHO when you sign up. Global parameter is MV_PAYMENT_SECRET or
ECHO_PAYMENT_SECRET.

others...

If planning to do AUTH_ONLY or other with special admin page
Variable MV_PAYMENT_REMAP order_id=mv_order_id
auth_code=mv_auth_code

Variable ECHO_PAYMENT_ORDER_TYPE S

# S for "self-service" orders
# F for hosted or ISP orders

Variable ECHO_PAYMENT_ISP_ECHO_ID 123<4567890
Variable ECHO_PAYMENT_ISP_PIN 12345608
Variable ECHO_PAYMENT_MERCHANT_EMAIL merchant@merchant.com Variable ECHO_PAYMENT_DEBUG F

# C causes ECHO to return a statement of conformity
# T or TRUE causes ECHO to return additional debug information # Any other value turns off ECHO debugging

Example Configuration

This is an example configuration that one would add to catalog.cfg:

Variable MV_PAYMENT_ID Your_ECHO_ID
Variable MV_PAYMENT_SECRET Your_ECHO_secret
Variable MV_PAYMENT_MODE echo

Troubleshooting

Try a sale with the card number "4111 1111 1111 1111" and a valid
expiration date. The sale should be denied, and the reason should be in [data session payment_error].

If nothing works:

o Make sure you "Require"d the module in interchange.cfg:

Require module Vend::Payment::ECHO

o Make sure the ECHO "OpenECHO.pm" module is available either in your

path or in /path_to_interchange/lib.

o Check the error logs, both catalog and global.

o Make sure you set your account ID and secret properly.

o 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.

o If all else fails, Interchange consultants are available to help

with integration for a fee.

SECURITY CONSIDERATIONS

Because this library calls an executable, you should ensure that no
untrusted users have write permission on any of the system directories or Interchange software directories.

NOTES

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