We just introduced pagination to the GET Absence API which unfortunately introduced a breaking change (this was not on purpose). Currently, the absence response is limited to 200 entries by default in case no pagination parameters are put in, which might break your implementation given we didn't previously limit the response.
We're currently working on the fix – you'll be only getting paginated results in case the parameters "limit" and "off-set" are passed in the API call. The changelog will be updated once this is implemented.
Sorry for the inconvenience! We learned our lesson here and will be more cautious in future releases.
