1. We are unable to extract the customerHappiness ( https://desk.zoho.com/DeskAPIDocument#CustomerHappiness#CustomerHappiness_ListallcustomerHappiness) object using the ticketNumber criteria. We keep getting HTTP 429 even when we limit to 60 calls per minute and implement a time delay on each call. This suggests the API is broken and there is no documentation on this rate limit.

2. The startDate/endData or startTime/endTime parameters of this customerHappiness API do not work. It is not documented exactly what date they filter on, we assumed it would be the ratedTime but it is not.

3. The maximum value of the customerHappiness API 'from' parameter appears to be only 280. This is not even documented and obviously very low.
