Thanks for the mail Alain, Currently i am using the "update-min" & "showdeleted=true" for the contacts, so i am getting the delta changes from the last sync and even able to identify which contacts are been deleted and which are updated, but i am facing issue when i use the same "update-min" & "showdeleted = true" for the calendar data API, actually the issue is, when i do this both the deleted and updated calendars/events used to get in the result but there is no field which distinguished whether its updated or deleted.
Can you please help me in get the field/key which i need to check for the difference for the calendars/events data. -- Regards, Satish Bellapu On Wed, Jun 22, 2011 at 11:21 PM, Alain Vongsouvanh <[email protected]>wrote: > Hello Satish, > > Unfortunately, the only Contact's field that contains an Etag (to track > changes) is the Contact's photo.
