FS::API - Freeside backend API

=head1 SYNOPSIS

  use Data::Dumper;

  my $url = new URI 'http://localhost:8008/'; #or if accessing remotely, secure
                                              # the traffic

  my $xmlrpc = new Frontier::Client url=>$url;

  my $result = $xmlrpc->call( 'FS.API.customer_info',
                                'secret'  => 'sharingiscaring',
                                'custnum' => 181318,
                            );

  print Dumper($result);

=head1 DESCRIPTION

This module implements a backend API for advanced back-office integration.

In contrast to the self-service API, which authenticates an end-user and offers
functionality to that end user, the backend API performs a simple shared-secret
authentication and offers full, administrator functionality, enabling
integration with other back-office systems.  Only access this API from a secure 
network from other backoffice machines. DON'T use this API to create customer 
portal functionality.

If accessing this API remotely with XML-RPC or JSON-RPC, be careful to block
the port by default, only allow access from back-office servers with the same
security precations as the Freeside server, and encrypt the communication
channel (for example, with an SSH tunnel or VPN) rather than accessing it
in plaintext.
