In Odoo 18.3 (Saas), there's a new setting to create a product feed for Google Merchant Center (GMC). It is under the Website settings, SEO section. I have enabled the option which creates a URL such as https://www.websitenamehere/gmc.xml
I have added this URL in GMC as a product data source. After trying to fetch data, Google responds with this error: "Authentication failed. Download failed due to authentication error. Please check username and password in your feed configuration and try again."
Anyone knows which username and password needs to be configured? The official Odoo documentation hasn't been updated yet and there's nothing about setting up GMC feed.
Did you see the draft documentation at https://github.com/odoo/documentation/pull/13957 - it might be easier to review it by logging into https://runbot.odoo.com/runbot/r-d-1?search=saas-18.3-ecommerce-google-merchant-center-lman (click the arrow pointing to the door icon) and then search for GMC
