Total number of Google Reviews using Google Places API
Unfortunately, there's no means to retrieve total user reviews anymore. Below is a list of issue trackers requesting that user_ratings_total
be added. The oldest one appears to date back to 2011.
https://issuetracker.google.com/u/1/issues/35820858
https://issuetracker.google.com/u/1/issues/35821787
https://issuetracker.google.com/u/1/issues/35823510
https://issuetracker.google.com/u/1/issues/35828637
Not only has user_ratings_total
been removed. But there seems to be no explanation as to why it has been removed. Odds are that Google has no interest in fixing the issue.
EDIT: as of 2019, it's now available in the Google Places API. See answers above.
Just reporting that this is fixed now. Reposting a comment from the Google Issue tracker:
The total amount of ratings is now generally available for all Places API clients as part of the Basic SKU:
https://developers.google.com/places/web-service/details#fields https://developers.google.com/places/web-service/place-data-fields#basic
Places API: user_ratings_total
Places SDK for Android: Place.Field.USER_RATINGS_TOTAL
Places SDK for iOS: GMSPlaceFieldUserRatingsTotal
As of Jan 2019 it is possible to get the total number of reviews using Place Details APIs call (user_ratings_total field): https://developers.google.com/places/web-service/details#fields
