Some improvements should be made on the Json pretty printer in our api:

{
  "tag":[{
    "tag1":"A",
    "tag2":"B" 
   },{
    "tag1":"C",
    "tag2":"D" 
   }]
}

should look like that:

{
  "tag": [ 
    {
      "tag1": "A",
      "tag2": "B" 
    },{
       "tag1":"C",
       "tag2":"D" 
    }
  ]
}
