Returns a summary of reviews grouped by the site they are from.
NOTE: Our docs provider has a bug that doesn't show the correct usage of the locationUids parameter.In order for the request to succeed, for each locationUid you are querying for add a &locationUids[] parameter to the url.For example: https://api.podium.com/v4/reviews/sites/summary?locationUids[]=00000000-0000-0000-0000-000000000000&locationUids[]=00000000-0000-0000-0000-000000000001
If no locationUids parameter is used then the data will be based on all locations that the caller has access to.
