Google provides conveniently short links you can use to send customers to your Google Maps listing, and can be used only on listings which are verified.

The short name is very helpful for requesting reviews from customers.
Given Google has changed the endpoints since the initial release, not using an endpoint will be just as effective for giving customers access to all facets of the listing – leaving reviews, making bookings, adding photos, and more.
