WebService::Xero

Perl CPAN style module to simplify integration with Xero API Applications

Inspired by the Xero endorsed Ruby API Library Xeroizer and the CPAN Net::Xero module, this Perl module aims to simplify integration with Xero API Applications points for Public, Private and in the future Partner application services. WebService::Xero modules primarily encapsulate the OAuth (v1.0a) access control protocol as described by Cubrid .

Active Development Version 0.13

• Support for PUT REST commands with examples such for example to create new accounts as per Xero Docs
• Supoprt for PDF handling
• More robust coverage of common usage in examples
• Reworking Date handling starting with Invoice class
• Refine overall design and address whether object instances are bound to Xero DB or whether can be created from data stand-alone
• Improve and expand exampels with actual useful snippets
• Improve documentation and include instructions for direct API access without needing the Xero Object classes.

Install from CPAN

This package is now available through CPAN

  perl -MCPAN -e 'install WebService::Xero'

XML-SAX Dependency

Because of dependencies on native XML libraries by some of the modules dependencies you may need to install native expat / xml libraries.

On AWS Linux you may need to install perl-XML-SAX using the package manager sudo yum install perl-XML-SAX perl-XML-Parser

For other platforms see the GitHub Wiki

Building from Source

Prerequisites

• Perl
• build tools ( make etc )
• Xero API Application with credentials as descibed in the Xero Developer Getting Started Guide

sudo apt-get install perl build-essential ## eg debian package install

Installing Manually

This Perl code is in the standard CPAN package format and can be installed through CPAN or downloaded and installed manually either from GitHub or CPAN:

  perl Makefile.PL
  make
  make test
  make install

Installing Step by Step

Download the latest stable source:

    git clone https://github.com/Combined-Computer-Professionals/WebService-Xero
    cd WebService-Xero

or Download the bleeding edge development version source:

    git clone https://github.com/pscott-au/CCP-Xero
    cd CCP-Xero

Configure your API credentials:

    cp t/config/test_config.tpl ./t/config/test_config.ini
    nano ./t/config/test_config.ini

Create the makefile

perl Makefile.PL

If given notice of missing dependency modules, these can be installed from CPAN. For example to install a missing Crypt::OpenSSL::RSA module:

    sudo perl -MCPAN -e "install Crypt::OpenSSL::RSA"
    ## or if you have cpanm installed
    cpanm --installdeps .

NB: Crypt::OpenSSL::RSA from CPAN requires SSL devel libraries which can be installed as follows:

  apt-get install libssl-dev   ## for debian etc
  yum install openssl-devel    ## for RH,Centos, Ubuntu etc

Set ENV vars if you require verbose testing.

export   RELEASE_TESTING=1
export   AUTHOR_TESTING=1

NB: you can also copy the template config file in t/config/test_config.tpl to t/config/test_config.ini to use API credentials in your testing

Make,test and install the library

make
make test
## or for verbose test
make test TEST_VERBOSE=1

make install

Usage

An example of a basic agent accessing a private Xero Application.

#!/usr/bin/perl
use strict;
use warnings;
use WebService::Xero::Agent::PrivateApplication;
use Data::Dumper;

my $xero = WebService::Xero::Agent::PrivateApplication->new( CONSUMER_KEY    => 'YOUR_OAUTH_CONSUMER_KEY', 
                                                    CONSUMER_SECRET => 'YOUR_OAUTH_CONSUMER_SECRET', 
                                                    PRIVATE_KEY      => '-----BEGIN RSA PRIVATE KEY-----.....etc'
                                                          );
## AND THEN ACCESS THE XERO API POINTS

my $contact_struct = $xero->do_xero_api_call( 'https://api.xero.com/api.xro/2.0/Contacts' );
print Dumper $contact_struct; ## should contain an array of hashes containing contact data.

An example of a minimalistic Mojolicious framework Public Application implementation can be found at github.com/pscott-au/mojolicious-xero-public-app-demo

There are also a couple of examples within the tests directory t and in the examples folder.
