I want to integrate Google Merchant Center with a 3rd party application database.
You will have to write a code in .Net only.
Using this code, you will pick the item details from the a Sample Database and PUSH into Google Merchant Center. Using .Net code, we should be able to Create, Read, Update and Delete item details in Google Merchant Center store in real-time using API authentication.
Apply only if you have worked before with Google Merchant Center API for automated datafeed uploading.
