Overview of the setup

Feed can be enabled via standard generic export job in the .

The structure of the product feed is CSV with the following required fields:

Google field	Corresponding Mapping	Memo
id	sku.code or product.code	You can choose to use sku or product entity depending on your setup
title	sku.displayName or product.displayName	You can choose to use sku or product entity depending on your setup
link	sku.seo.uri or product.seo.uri	You can choose to use sku or product entity depending on your setup Note that you need to use a template to generate full URL, do NOT forget to include the warehouse code e.g. "https://www.myshop.com/fc/MAIN/product/$1"
image_link	IMAGE0 atrribute on sku or product	You can choose to use sku or product entity depending on your setup Use AVC data type to look up the attribute value e.g. "https://www.myshop.com/imgvault/product/$1"
additional_image_link	IMAGE1 atrribute on sku or product	You can choose to use sku or product entity depending on your setup Use AVC data type to look up the attribute value e.g. "https://www.myshop.com/imgvault/product/$1"
price		Use PRICE data type to look up the minimal price. Use template as google expects the currency included e.g. "$1 CHF"
shipping		At the moment it is recommended to hardcode the common shipping option with fixed shipping cost e.g. "CH:::4.95 CHF" (CH is the code for your region and extra colons are separators for shipping attributes, which you can leave as default)
availability		hardcode to "in_stock"
condition		hardcode to "new"
brand	sku.product.brand.name or product.brand.name	You can choose to use sku or product entity depending on your setup
gtin	sku.barCode or product.attribute.XXXX	You can choose to use sku or product entity depending on your setup if you use product store GTIN in an attribute and use AVC data type
mpn	sku.nanufacturerCode or product.manufacturerCode	You can choose to use sku or product entity depending on your setup

Note that in your descriptor you need to specify full path on the server where to put the file. It is recommended to place it in one of the apache resource directories for your site. Ensure you specify the resource path to avoid proxy to tomcat.

...
# Map /r to /resources file path
Alias /r /var/www/shop10/resources
...
# allow URLS under /r to pass and not fall unto tomcat proxy pass rule
ProxyPass /r !
...
ProxyPass / ajp://localhost:8012/
...
<Directory /var/www/shop10/>
        Options -Indexes -FollowSymLinks -MultiViews
        AllowOverride None
        Order allow,deny
        allow from all
</Directory> 
...

...
    <export-file-descriptor>
        <file-encoding>UTF-8</file-encoding>
        <file-name>/var/www/shop10/resources/2l8YSRX1tTAQq_merchantcentre.csv</file-name>
        <print-header>true</print-header>
        <column-delimiter>,</column-delimiter>
        <text-qualifier>&quot;</text-qualifier>
    </export-file-descriptor>
...

In the above example the feed file would be generated to "/var/www/shop10/resources/" and will be available under the URL: www.myshop.com/r/2l8YSRX1tTAQq_merchantcentre.csv

Example export descriptor

You need to define export descriptor for generating the CSV file and create a corresponding Export Group (in this example we use: "SHOP10: Merchant Centre Product Feed CSV").

Both of which can be setup from the Admin application.

Example export descriptor for "product" entity is listed below:

Example SQL to insert the JOB

The job configuration need to be setup via SQL (see example below) and it will be required to restart the Admin application for the changed to take effect in the job scheduler.

INSERT INTO TJOBDEFINITION (GUID, JOB_NAME, PROCESSOR, CONTEXT, HOST_REGEX, DEFAULT_CRON, DEFAULT_PAUSED)
  VALUES ('shop10MCProductFeedCSV', 'SHOP10: Merchant Centre Product Feed CSV', 'genericExportGroupProcessor', 
'config.user=
config.pass=
export.group=SHOP10: Merchant Centre Product Feed CSV',
  '^(ADM)$', '0 45 8 * * ?', 1);

Merchant Centre Specific Tips

You will require to setup online channel and verify it in the merchant centre, so that you are able to use the online sales channel.
Ensure you setup default shipping settings in the merchant centre
When setting up the feed, ensure that you uncheck the "local stores listings" checkbox under the Data > Marketing Methods section (otherwise you may receive an error about not providing inventory)
Set your feed to automatically be consumed (daily is preferred option)
For the first use before the products will be considered for review you will require to send a manual request for site validation (this is usually done from the products menu). Note that no products will be processed until this verification is completed
