Clear the cache in v4 by appending ?ctpl&cc to the admin.php URI.

Suggested way for overriding an entire template is to edit the original, putting a hook around the entire thing. Then override the hook.

table cscart_payment_processors

  processor_id        int
  processor           string
  processor_script    string
  processor_template  string
  admin_template      string
  callback            char default 'N' -- not used
  type                char default 'P'

Areas:
  'C' client
  'A' admin

notifications:
  'C' customer
  'A' department
  'V' vendor

var/themes_repository/basic/templates/common/scripts.tpl
  includes the core javascript libraries
  executes $.runCart('C'), defined in js/tygh/core.js

js/tygh/core.js
  defines the Tygh object
  Tygh is generally passed as _
  assigns document to _.doc
  extends jquery
  $.runCart():
    attaches click, mousedown, keyup, keydown, and change events to $(_.doc)

For each parameter in the callback url, verify that it is correct for the stored order.

// paypal.php
$account_type = fn_validate_email($processor_data['processor_params']['account']) ? 'receiver_email' : 'receiver_id';
if ($_REQUEST[$account_type] != $processor_data['processor_params']['account']) {
    $pp_response['order_status'] = $paypal_statuses['denied'];
    $pp_response['reason_text'] = __('paypal_security_error');
    fn_finish_payment($_REQUEST['order_id'], $pp_response);
    exit;
}

payment_processors table is queried from functions (incomplete list):

  app/functions/fn.cart.php fn_get_payment_methods
  app/functions/fn.cart.php fn_get_checkout_payment_buttons
    creates empty array $checkout_buttons
    "include"s each payment processor's processor_script
    returns $checkout_buttons
    amazon and google payment methods populate $checkout_buttons
