How accurate Google My Business api returns the Reviews for all locations of an account?

Question

I want to know if google my business api returns ALL reviews in each call or it might not return some of them if the number of reviews are a lot? Using this link
(https://developers.google.com/my-business/reference/rest/v4/accounts.locations.reviews/list) , my code is based on the code provided here (https://developers.google.com/my-business/content/review-data#list_all_reviews). The account I am listing its reviews has more than 83000 reviews for its all locations and once I execute the code it might return about 81000 reviews and the second time 2 or 3 thousands more and another time 75000 reviews. Has anyone encountered something similar?

Answer 1

This is a known bug for locations with many reviews, the only workaround that exists is already close what you are describing: iterate through the reviews multiple times and aggregate all distinct reviews.
