Get Apple App Reviews Results by id
This endpoint will provide you with feedback data on applications listed on the App Store platform, including review ratings, review content, user profile info of each reviewer, review publication dates, and more. The results are specific to the app_id as well as the location and language parameters specified in the POST request.
We emulate set parameters with the highest accuracy so that the results you receive will match the actual search results for the specified parameters at the time of task setting. You can always check the returned results accessing the check_url in the Incognito mode to make sure the received data is entirely relevant. Note that user preferences, search history, and other personalized search factors are ignored by our system and thus would not be reflected in the returned results.
