Getting Throttled frequently

Hi,

We are using java sdk for fetching enterprise events. Sdk version we are using 2.28.1. We are getting throttled very frequently i.e even after fetching enterprise events 1 or 2 times. Sometimes we get throttled at first time only. The url equivalent of the code is as follows.

https://api.box.com/2.0/events?stream_type=admin_logs&limit=400&stream_position=0&created_after=2020-03-04T11:34:15&created_before=2020-09-15T09:40:40&event_type=UPLOAD,EDIT,MOVE,COPY,GROUP_ADD_ITEM,UNDELETE,ITEM_SHARED_UPDATE,CHANGE_FOLDER_PERMISSION,COLLABORATION_ACCEPT,COLLABORATION_ROLE_CHANGE,UPDATE_COLLABORATION_EXPIRATION,COLLABORATION_INVITE,CONTENT_WORKFLOW_SHARING_POLICY_VIOLATION,COLLABORATION_REMOVE,COLLABORATION_EXPIRATION,SHARE

Enterprise id: 164726455

Any help would be appreciated. 

Thanks in advance,

Bharath
