Google Shopping product stars

I'm trying to show my customers' ratings of products on Google Shopping but I can not do it.

Could someone tell me how I can do this?

I speak of the reviews and the stars that customers leave after buying a product.

Thanks

You need to get an approved product review company to manage the reviews on your site. You can see more here:

There is a list of supported vendors here:

Note that's for Seller Ratings, as opposed to Product Ratings, but the process is the same.
