       }
    ]
  }

}

How can I create body, to remove unit with  source text":"word2",  target text":"trans2" and fields [{\"Values\":[\"string\"],\"ValueType\":2,\"Name\":\"Brand\"},{\"Values\":[\"string\"],\"ValueType\":2,\"Name\":\"Project\"},{\"Values\":[\"additionalString\",\"string\"],\"ValueType\":2,\"Name\":\"Project Type\"},{\"Values\":[\"string\"],\"ValueType\":2,\"Name\":\"Text Type\"}]"
