You should use method PATCH like described in RFC-7386 "json merge PATCH".

E.g. if you want to change value of "a" and removing "f" in resource like:

   {
     "a": "b",
     "c": {
       "d": "e",
       "f": "g"
     }
   }

You can achive this by sending:

       PATCH /target HTTP/1.1
       Host: example.org
       Content-Type: application/merge-patch+json

       {
         "a":"z",
         "c": {
           "f": null
         }
       }
