Install the php SDK

The instructions on this page describe how to install the QuickBooks Online PHP SDKwith or without Composer Dependency Manager.

• PHP 5.6 or greater
• To use the PHP Guzzle handler, install guzzlehttp/guzzle via Composer
• To use the cURL handler, you must have cURL version 7.19.7 or greater compiled with OpenSSL

The recommended way to install the QuickBooks SDK is with Composer. Composer is a dependency management tool for PHP that allows you to declare the dependencies your project needs and installs them into your project. If you are not familiar with Composer Dependency Manager for PHP, see the Getting started page on the Composer website. To install Composer:

1

curl -sS https://getcomposer.org/installer | php

To add the QuickBooks SDK as a dependency using the composer.phar CLI:

1

composer require quickbooks/v3-php-sdk

Alternatively, you can specify the QuickBooks SDK as a dependency in your project’s existing composer.json file:

{
   "require": {
      "quickbooks/v3-php-sdk": ">=4.0.1"
   }
}

After installing, require Composer’s autoloader:

1

require 'vendor/autoload.php';

For more on how to install Composer, configure autoloading, and other best practices for defining dependencies, go to getcomposer.org.

If you are not familiar with Composer, or Composer is not compatible with your environment, you can download the zip file either from the PHP page or form the Releases tab of the PHP SDK repository. For example scripts, go to _Samples for how to make QuickBooks Online API calls without Composer. You will need to include the necessary autoloader:
