Based on google documentation, I am calling the endpoint for fetching all reviews like here:
curl \
'https://androidpublisher.googleapis.com/androidpublisher/v3/applications/com.questionpro/reviews' \
--header 'Authorization: Bearer [myAccessToken] \
--header 'Accept: application/json' \
--compressed
but this endpoint returns an empty objec {}, like there is no review to fetch but there are:
If you check the doucmenation for Retrieving a set of reviews you will find it states.
Which implies to me that you have no new reviews in the last week so that is why your getting an empty object. If you want all the reviews then your going to have to download the cvs file via play store. This can not be done via the api.
