The fields parameter is used to control which fields, of an resource, should be included in the JSON response. The fields parameter can be applied to any GET request. The fields parameter value is specified as a single field name, or a comma separated list of field names, that should be included in the response.
For example, this query returns only the id and name fields of all Deployments in the catalog:
GET http://www.nirmata.io/catalog/api/deployments?fields=id,name,kind,apiVersion Accept: application/json
