=head1 NAME

Net::Stripe::Simple - simple, non-Moose interface to the Stripe API

=head1 SYNOPSIS

  use Net::Stripe::Simple;

  my $stripe = Net::Stripe::Simple->new('sk_test_00000000000000000000000000');

  # when the only argument is an id, that's all you need
  my $c1 = $stripe->customers( retrieve => 'cus_meFAKEfakeFAKE' );

  # you can provide arguments as a hash reference
  my $c2 = $stripe->customers( retrieve => { id => 'cus_ImFAKEfakeFAKE' } );

  # or as key-value list
  my $c3 = $stripe->customers( 'retrieve', id => 'cus_I2FAKEfakeFAKE', expand => 1 );

=head1 DESCRIPTION

A lightweight, limited-dependency client to the stripe.com API. This is just
a thin wrapper around stripe's RESTful API. It is "simple" in the sense that it
is simple to write and maintain and it maps simply onto Stripe's web
documentation, so it is simple to use. When you get a response back, it's just
the raw JSON blessed with some convenience methods: stringification to ids and
autoloaded attributes (L<Net::Stripe::Simple::Data>). If there is an error, the
error that is thrown is again just Stripe's JSON with a little blessing
(L<Net::Stripe::Simple::Error>).

This simplicity comes at a cost: L<Net::Stripe::Simple> does not
validate your parameters aside from those required to construct the URL before
constructing a request and sending it off to Stripe. This means that if you've
done it wrong it takes a round trip to find out.

For the full details of stripe's API, see L<https://stripe.com/docs/api>.

=head2 Method Invocation

Following the organization scheme of Stripe's API, actions are grouped by entity
type, each entity corresponding to a method. For a given method there are
generally a number of actions, which are treated as the primary key in a
parameter hash. Parameters for these actions are provided by a parameter hash
which is the value of the primary key. However, there is some flexibility.

Methods that require only an id are flexible. All the following will work:

  $stripe->plans( retrieve => { id => $id } );
  $stripe->plans( 'retrieve', id => $id );
  $stripe->plans( retrieve => $id );

Methods that require no arguments are also flexible:

  $stripe->plans( list => { } );
  $stripe->plans('list');

=head2 Export Tags

L<Net::Stripe::Simple> exports nothing by default. It has four exportable
constants and one exportable function:

=over 4

=item true

=item false

=item null

=item data_object

=back

To facilitate their export, it has two tags:

=over 4

=item :const

The three constants.

=item :all

The three constants plus C<data_object>.

=back

=head1 METHODS

=head2 new

  Net::Stripe::Simple->('sk_test_00000000000000000000000000', '2014-01-31')

The class constructor method. The API key is required. The version date is
optional. If not supplied, the value of C<$Net::Stripe::Simple::STRIPE_VERSION>
will be supplied. L<Net::Stripe::Simple> was implemented or has been updated
for the following versions:

=over 4

=item 2014-01-31

=item 2014-06-17

=back

The default version will always be the most recent version whose handling
required an update to L<Net::Stripe::Simple>.

Recipients have been deprecated and are no longer available in the Stripe API,

=head1 FUNCTIONS

=head2 data_object($hash_ref)

This function recursively converts a hash ref into a data object. This is just
L<Net::Stripe::Simple::Data>, whose only function is to autoload accessors for
all the keys in the hash. It is made for adding magic to JSON objects. If you
try to give it something that contains blessed references whose class is
outside the JSON namespace it will die.

=head1 SEE ALSO

L<Net::Stripe>, L<Business::Stripe>

=head1 EXPORTED CONSTANTS

These are just the corresponding L<JSON> constants. They are exported by
L<Net::Stripe::Simple> for convenience.

  use Net::Stripe::Simple qw(:const);
  ...
  my $subscription = $stripe->subscriptions(
      update => {
          id       => $id,
          customer => $customer_id,
          plan     => $plan_id,
          prorate  => true,
      }
  );

You can import the constants individually or all together with C<:const>.
