Vend::Payment::TestPayment(3) Interchange payment test module




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




The Vend::Payment::TestPayment module implements the testpayment() routine for use with Interchange. It's compatible on a call level with the other Interchange payment modules --- in theory (and even usually in practice) you could switch from TestPayment to another payment module with a few configuration file changes.

The module will perform one of three actions:

  • If the card number is 4111111111111111 then the transaction will be approved.
  • If the card number is 4111111111111129 then the transaction will be declined.
  • Any other card number will raise an error and the transaction will be declined.

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

    Require module Vend::Payment::TestPayment

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 "testpayment". 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  testpayment

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=testpayment id=testid]


    Route testpayment id testid


    Variable MV_PAYMENT_ID      testid

The active settings are:

A test account ID, which can be any value you like. Global parameter is MV_PAYMENT_ID.
A test account password, which can be any value you like. Global parameter is MV_PAYMENT_SECRET. This is not needed for test charges, using this module, but you may as well set it up anyway.
The type of transaction to be run. Valid values are:


Actually, the transaction type is ignored in this version, but you may as well set it anyway.

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


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

        Require module Vend::Payment::TestPayment
  • 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, Cursor Software and other consultants are available to help with integration for a fee.


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