This endpoint retrieves aggregate ratings for service reviews by channel ID.
The response will contain aggregates for five periods of time: the last seven, 30, 90 days, the last year, and overall.
If the overall period of collecting reviews is shorter than one or several of the fix periods, the aggregates will still be calculated and returned.
For example, if a channel only collects service reviews for 14 days, the result will still contain the aggregates for 30, 90 and 365 days, but they will be the same, except for the start property.
NB: For the aggregate, only verified reviews are considered, meaning unverified reviews such as imported ones are excluded.
