💡 Google API - How to add a supplemental feed?

Google switched from the Inventory API to the Supplemental feed in February 2020.

This feed allows an hourly update of offers for the Google Shopping and Google Shopping Display Ads services. 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 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.

  • Name this new feed, then select "Content API"and click on "Continue"

    • If you have several main feeds, once you have selected "Content API", select the "country/language" combination that corresponds to the feed in your Lengow account (ex: "France, English" for your Shopping Actions FR feed in English in Lengow). You have to select only one combination. If you select more than one combination at a time, this will produce errors.

  • Then click on "Create feed"
  • 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.
