Changes list v1

Note: The latest specification for Collaborate 4.1.4 and above is here

This API helps to fetch a list of changes to the files / folder resource since the last sync operation by the client. The changes API is based on event / audit logs which make up our admin audit reports. The changes list is time-sequenced list maintained separately for each user and device. We call it sync_position. When a client application wants to fetch the changes since the last fetch operation, they send over their sync_position in the GET request and we return all changes since the sync_position. The content returned in to the client are paginated. Individual resource items are embedded in the response content.

To initialize the client call the changes API with an empty sync_position and all events related to the specific folder will be sent to the client. The client can send a sync_position=current to get the current sync position.

Workflow for the client application being setup for the first time

·      A client that has just been configured can call sync_position = current to get the current sync position 

·      Call the /files API to get a list of all of the files for the specific folder

·      Call the /changes API to get hold of any changes since the sync_position = current

·      Decide how frequent to call the server API based on the total_changes for the specific client on the server.

The above call sequence will help the client to initialize the sync folder. 

Any actions taken by the specific client are recorded in the events log with the id of the specific source. 

Purpose

The purpose of this API is to give you sync changes detail. Anyone can call this API to get sync changes detail.

3.     Optional query parameter details are as under:
   syncpositionid : – next sync position id if provided then sync changes greater than these id will be given otherwise response with current sync position id only (without activities).If syncpositionid=0 then first 500 top activities will be given in the response.
   limit : – to limit the number of records if provided then no of sync changes will be given otherwise default is 500.
   contenttype : – to get the specific content like 'Files' (it is only one right now). If provided then will give specific type of sync changes record otherwise all types will be delivered. "contenttype=files" will return both file and folder contents.
   siteid : – This is to get filter by site. If provided then will give site specific sync changes otherwise all.
Ex: /api/1/changes?syncpositionid=40&limit=30&contenttype=files&siteid=1

4.     If the user wants to provide the sourceclient for Every API call(/User Events) then they need to provided dynamic value through the query parameter called "sourceclient" E.g. sourceclient=MyPC in the URL.

5.     "sourceclient" text limit is max 50 characters. If longer "sourceclient" value is provided then it will be automatically trimmed to first 50 characters only.

8.    File & folder permanently deleted events will not be coming while get sync changes list in changes API.
