@Sunile Manjee

Below is an example to create type.

Save below json to some file(example type.json)

{
  "enumTypes": [
    
  ],
  "structTypes": [
    
  ],
  "traitTypes": [
    
  ],
  "classTypes": [
    {
      "superTypes": [
        
      ],
      "hierarchicalMetaTypeName": "org.apache.atlas.typesystem.types.ClassType",
      "typeName": "myNewType1",
      "typeDescription": null,
      "attributeDefinitions": [
        {
          "name": "multiplicityRequired",
          "dataTypeName": "string",
          "multiplicity": "required",
          "isComposite": true,
          "isUnique": true,
          "isIndexable": true,
          "reverseAttributeName": null
        }
      ]
    }
  ]
}

Submit HTTP POST request to atlas to create a type of above.

Command:
curl -X POST -d @type.json -u <username>:<password> -H 'Content-Type: application/json;  charset=UTF-8' http(s)://<atlas-hostname>:<atlas-port>/api/atlas/types


Output:
{"requestId":"qtp513700442-26 - b84cee5b-7940-4308-a35b-fc9af5de0b81","types":[{"name":"myNewType1"}]}

@Ayub Pathan Do I have to fatten the json string or will it accept the formatted version you posted?

@Sunile Manjee you can try as it is but either ways should be fine.
