Please note that I'm very new in Retail domain and use of Google Cloud Retail API.
I'm very confused regarding the offerings of Retail from Google cloud. I started using Google Retail for implementation of an e-commerce platform where different Seller can list their product and Buyer can buy.
Now my confusion/question is that can I use the Retail API without my own implementation of services like inventory, product variants, cart etc. If no then how to combine them with my services.
Thanks in advance!
