In addition to allowing you to publish on Google Shopping with the appropriate feed format, you can now keep your stock and prices updated in real-time thanks to our new engine technology and the Google API platform.
Prerequisites
Your Google Merchant Center account must already have a primary feed(source), which is most often the feed generated by Google Shopping.

Configuration and Settings

2. Retrieve the Feed ID (Identifier of the new Supplemental Feed):

3. Open and Connect the Google API Platform:

4. Enter the Merchant ID and Feed ID during Authentication:
