Create your product data
Once you set up your account, you're ready to create and upload your product data. You can send us your product data in a feed format, via the Google Content API for Shopping, or import your product data from a supported e-commerce platform. Unless you are comfortable using API, we recommend that you use feeds or imports from your e-commerce platform.
A feed is a file that contains all the information about the products you sell. The different pieces of information about your products are described in attributes, which allow customers to search for and find your items. Learn more about using feeds.
E-commerce platform imports
If you use a supported e-commerce platform, you can link your Merchant Center account to your store account and automatically import your product data. This allows for information from your store to continuously update in Google Merchant Center without any additional work.
Google Content API for Shopping (Advanced)
The Content API for Shopping lets you programmatically manage the structured data items you upload to Google for use in Google properties, such as Google Shopping and Web Search. The API allows you to query for items and insert, update, and remove items in your Google Merchant Center account.
The Google Content API for Shopping is designed for developers who would like to integrate applications with Google Shopping. Due to the nature of the Google Content API for Shopping, developers should have some technical know-how and experience in programming applications. Learn more about Google Content API for Shopping.
