I am importing data from service cloud to third party. Currently I am sending whole dataset to third party, which is not accepted by them.

Only I need to send the changed data and contact id to third party. For example, in the service cloud, if the user changes first name then I should send only contact=1&FirstName=chidam to third party. 

I wondering service cloud API supports these kind of features.

Any input on this is highly appreciated.

thanks,

I didn't find the right solution from the internet.
