The Google Supplemental feed allows an hourly update of offers for the Google Shopping and Google Shopping Display Ads services.Â
It has to be used along with the Google API - Services feed in Lengow.
How to do it?
1. Create the supplemental feed in your Google Merchant Center Next account
-
Select the sub-account where your Google API feed is sent from Lengow
The Merchant ID at the top of your browser must be the same as the one entered in the "Settings" tab of your Google API feed on Lengow (see screenshots below).
- Go to "Settings and tools" (cog icon) > click on "Data sources".
- Then, in "Supplemental sources", click on "Add supplemental product data"
Can't find the "Supplemental sources" section?
If the the "Supplemental sources" section if not available, you need to activate the corresponding Add-on.
Go to "Settings and tools" (cog icon) and click on "Add-ons". Then, add "Advanced data source management".
Note: If you already had a supplemental feed in the classic Merchant Center, this add-on is already activated automatically in your Google Merchant Center Next.
- Select "Add product data using API", name this new feed, and click on "Continue"
-
Select the primary data source to which this supplemental data source is added.
If you have several primary sources, make sure to select the "country/language" combination that corresponds to the channel in your Lengow account (ex: "France, English" for your Google Shopping FR channel is in English in Lengow). Select only one combination - if you select more than one combination at a time, this will produce errors.
- Then click on "Create data source"
- Verify that this feed has been added to your Google Account, that its format is "Content API" and that the country/language combination is correct:
-
Retrieve the ID of this new supplemental feed by clicking on the name of the supplemental source and copying the ID found in the URL after "joinFeedId=" (see screenshot below).
2. Fill in the supplemental feed ID in your Lengow account
In your Lengow account:
- Go to "Channels" and select your Google API channel (the one corresponding to the country/language feed you just created, e.g.: FR).
- In the "Configuration" tab of the channel, go to the "Settings" step.
- Click on "Edit":
- Fill in the ID in the "Supplemental Feed ID" field:
Make sure to leave the Merchant ID unchanged in the field above!
Special cases:
-
Your Lengow account contains multiple Google API feeds
Repeat the steps above as many times as you have Google API feeds in Lengow.
-
Your GMC contains multiple Google API feeds
In your Google Merchant Center, you should have as many supplemental feeds as there are "Content API" primary sources.
