GoogleShoppingAPI v2

Update to 0.2.4

IMPORTANT!

If you are updating to 0.2.4 from an earlier version, please be aware that the category ids have changed. There is a shell script which might help you to map the old category ids to the new ones.

Fortunately Google has added static category ids which makes it easier for future updates.

Magento Module GoogleShoppingAPI

This module is based on the official Magento GoogleShopping module and enhances the original module features with APIv2 support (APIv1 support removed), OAuth2 support and several additional features from the original EnhancedGoogleShopping module.

If the original Magento GoogleShopping module is installed, data will be migrated.

The observer (auto sync after saving product changes) is disabled in the current version, but will be re-enabled soon.

The observer was re-enabled with version 0.1.0 . To prevent problems when users are editing products which have no access to GoogleShopping through OAuth2, products are only updated on GoogleShopping if a valid access token for the store exists.

To authenticate and get an access token go to Magento Admin -> Catalog -> Google Content APIv2 and select the store view in which you want to authenticate. After selecting a store view without valid access token you will be automatically redirected to OAuth2 authentication.

Features

• update item expiration date on sync
• option to renew not listed items on sync
• option to remove disabled items on sync
• convert html entities in description to UTF-8 chars
• strip tags from description
• make sales price available in countries outside the US
• possibility to define a separate google shopping image with base image fallback
• option to add Google Analytics source to product link (utm_source=GoogleShopping)
• option to add custom parameters to product link
• adds Austria as target country
• ability to set Google product category in Magento product details
• ability to use OAuth2 service account
• Automated daily sync to Google Content
  • Option to enable by StoreView
  • At the moment the products are synced every day at 02:30 (cron)
  • Needs improvement in future versions (e.g. batch processing, option to set sync period)

Installation

Install using composer

As the Google ApiClient must be installed in addition, it is recommended to install using composer.

Create or adapt the composer.json file in your Magento root directory with the following content:

{
	"require": {
		"bluevisiontec/googleshoppingapi": "*",
		"magento-hackathon/magento-composer-installer": "*",
		"google/apiclient": "*"
	},
	"repositories": [
		{
			"type": "composer",
			"url": "http://packages.firegento.com"
		},
		{
				"type": "vcs",
				"url": "https://github.com/bluevisiontec/GoogleShoppingApi"
		}
	],
	"extra": {
		"magento-root-dir": "./",
		"magento-deploystrategy": "copy"
	}
}

Install composer

mkdir bin
curl -s https://getcomposer.org/installer | php -- --install-dir=bin
php bin/composer.phar install

Install manually

• Copy app, js, var to your magento root directory
• Download Google Content API Client for PHP Release 1.1.6: https://github.com/google/google-api-php-client/archive/1.1.6.tar.gz
• Install Google Content API to [MAGENTO_ROOT]/vendor/google/apiclient/
• You should have at least the autoload.php file and the src folder in [MAGENTO_ROOT]/vendor/google/apiclient/

After installation

• Clean the Magento Cache and log out of the backend

Configuration

As the module has to use Google OAuth2, credentials for Google Content API are required. Those can be generated in the http://console.developers.google.com/

You can choose between using a Client ID for web application or using a service account. If the Client ID for web application is used a manual user interaction is needed to provide access to Google Content API. In this case automated processes like cron jobs are not available.

Using a service account is recommended and needed if you want to use automated processes.

Using Service account

Create a project in Google developers console

• Login to Google developers console or create an account
