=head1 NAME

iTunesConnect - An iTunesConnect client interface

=head1 SYNOPSIS

 use WWW::iTunesConnect;

 my $itc = WWW::iTunesConnect->new(user=>$user, password=>$password);
 my %report = $itc->daily_sales_summary;

=head1 DESCRIPTION

C<iTunesConnect> provides an interface to Apple's iTunes Connect website.
Daily, Weekly and Monthly summaries, as well as Finanacial Reports, can be
retrieved. Eventually this will become a complete interface.

A script suitable for use as a nightly cronjob can be found at
L<http://github.com/bfoz/itunesconnect-tools>

=head1 CONSTRUCTOR

=over

=item $itc = WWW::iTunesConnect->new(user=>$user, password=>$password);

Constructs and returns a new C<iTunesConnect> interface object. Accepts a hash
containing the iTunes Connect username and password.

=back

=head1 ATTRIBUTES

=over

=item $itc->user

Get/Set the iTunes Connect username. NOTE: User and Password must be set 
before calling any other methods.

=item $itc->password

Get/Set the iTunes Connect password. NOTE: User and Password must be set 
before calling any other methods.

=back

=head1 Class Methods

=over

=item %report = WWW::iTunesConnect->parse_sales_summary($input, %options)

Parse a gzip'd summary file fetched from the Sales/Trend page. Arguments are 
the same as the L<IO::Uncompress::Gunzip> constructor, less the output argument.
To parse a file pass a scalar containing the file name as $input. To parse a 
string of content, pass a scalar reference as $input. The %options hash is 
passed directly to I<gunzip>.

The returned hash has two elements: I<header> and I<data>. The I<header> element 
is a reference to an array of the column headers in the fetched TSV file. The 
I<data> element is a reference to an array of array references, one for each 
non-header line in the fetched TSV file.

=back

=head1 METHODS

These methods fetch various bits of information from the iTunes Connect servers.
Everything here uses LWP and is therefore essentially a screen scraper. So, be
careful and try not to load up Apple's servers too much. We don't want them to
make this any more difficult than it already is.

=over

=item $itc->login()

Uses the username and password properties to authenticate to the iTunes Connect
server. This is automatically called as needed by the other fetch methods if 
user and password have already been set.

=item $itc->daily_sales_summary_dates

Fetch the list of available dates for Sales/Trend Daily Summary Reports. This
caches the returned results so it can be safely called multiple times. Note, 
however, that if the parent script runs for longer than 24 hours the cached
results will be invalid.

Dates are sorted in descending order.

=item $itc->daily_sales_summary()

Fetch the most recent Sales/Trends Daily Summary report and return it as a
hash of array references. The returned hash has two elements in addition to the 
elements returned by I<parse_sales_summary>: I<file> and I<filename>. The 
I<file> element is the raw content of the file retrieved from iTunes Connect 
and the I<filename> element is the filename provided by the Content-Disposition 
header line.

If a single string argument is given in the form 'MM/DD/YYYY' that date will be
fetched instead (if it's available).

=item $itc->fetch_financial_report($month, $region)

Fetch the raw report content for a given month and region. The month argument
must be of the form 'YYYYMM' and the region argument is the name of a region
as listed on the Financial Reports page of iTunes Connect.

Returns a hash with two keys:

    Key		Description
    -----------------------------------------------------------------------
    filename	The report filename as listed on the Financial Reports page
    content	Raw content of the report file

=item $itc->financial_report_list()

Fetch the list of available Financial Reports. This caches the returned results 
and can be safely called multiple times.

=item $itc->financial_report()

Fetch the most recent Financial Report and return it as a hash. The keys of the 
returned hash are of the form 'YYYYMM', each of which is a hash containing one 
entry for each region included in that month's report. Each of the region 
entries is a yet another hash with six elements:

    Key		Description
    ---------------------------------------------
    currency	Currency code
    data	Reference to array of report rows
    file	Raw content of the retrieved file
    filename	Retrieved file name
    header	Header row
    total	Sum of all rows in data

If a single string argument is given in the form 'YYYYMM', that month's report 
will be fetched instead (if it's available).

=item $itc->monthly_free_summary_dates

Fetch the list of available months for Sales/Trend Monthly Summary Reports. This
caches the returned results so it can be safely called multiple times.

Months are returned as an array of hash references in descending order. Each 
hash contains the keys I<From> and I<To>, indicating the start and end dates of 
each report.

=item $itc->monthly_free_summary( %options )

Fetch the most recent Sales/Trends Monthly Summary report and return it as a
hash of array references. The returned hash has two elements in addition to the 
elements returned by I<parse_sales_summary>: I<file> and I<filename>. The 
I<file> element is the raw content of the file retrieved from iTunes Connect 
and the I<filename> element is the filename provided by the Content-Disposition 
header line.

If both I<From> and I<To> options are passed, and both are of the form 
'MM/DD/YYYY', the monthly summary matching the two dates will be fetched 
instead (if it's available). The hashes returned by monthly_free_summary_dates()
are suitable for passing to this method.

=item $itc->weekly_sales_summary_dates

Fetch the list of available dates for Sales/Trend Weekly Summary Reports. This
caches the returned results so it can be safely called multiple times.

Dates are sorted in descending order.

=item $itc->weekly_sales_summary()

Fetch the most recent Sales/Trends Weekly Summary report and return it as a
hash of array references. The returned hash has two elements in addition to the 
elements returned by I<parse_sales_summary>: I<file> and I<filename>. The 
I<file> element is the raw content of the file retrieved from iTunes Connect 
and the I<filename> element is the filename provided by the Content-Disposition 
header line.

If a single string argument is given in the form 'MM/DD/YYYY' the week ending 
on the given date will be fetched instead (if it's available).
