structure of data for api call

[iamshivam007]

When student update details. what will be the structure of json data for API call

1. We can send all data in one API call.
   prons: only one API have to call
   cons : when student made a small update we have to send whole data for updation.

2. We cal call one API per database table model.
   prons: when student update information we have to send only related model data
   cons: we have to call five API first time when user create profile and fill all data.

   More suggestion are welcome..
