Content API in Merchant Center
The Content API for Shopping allows apps to interact directly with the Merchant Center platform, vastly increasing the efficiency of managing large or complex Merchant Center accounts. The Content API for Shopping can be used as an input source for product data in Merchant Center, directly delivering your data as it is updated on your site.
Note: If you plan to upload a large number of feeds or make frequent changes to your product data, it is strongly recommended that you use the Content API (instead of feeds) to directly upload your product data.
If you choose to submit your product data through the Content API and there isn't an input feed already in place, a feed will automatically be created in Merchant Center. This new feed allows you to create custom feed rules for your API data and manage your feed within the Merchant Center product. Alternatively, you can create a placeholder feed for your Content API and upload the API product data to the placeholder feed.
Submitting to multiple countries
Due to the nature of the Content API, items will not be replicated for multiple countries within a single feed. If you want to submit your Content API product data to multiple countries, you must create multiple input feeds with the new target countries and languages.
Product data uploads through the Content API aren't supported for standard supplemental feeds. Retailers who are enabled for local inventory ads can use the Content API for local inventory feeds.
In place of the Content API for standard supplemental feeds, you can use regular feeds to provide product data. This allows you to submit product data that may not be available in the content API, or add additional information to your existing product data, such as more robust
descriptions or product
conditions. Learn more about creating and linking supplemental feeds.
