Ways to submit your products
We currently provide several options for you to submit your product information to us.
We recommend creating a data feed which contains all of your content in a single tab-delimited text or XML file. You can send us your data feed directly through your Google Merchant Center account, or by using File Transfer Protocol (FTP).
The Content API for Shopping is designed for developers with technical know-how who would like to integrate their applications with Google Merchant Center. Your application can upload new data, update or delete existing items, and query Google Merchant Center data to find matches for complex attribute criteria. The Content API for Shopping uses the same underlying protocol as the other Google Data APIs.
