[   {     "id": 1,     "title": "brooklyn"   },   {     "id": 2,     "title": "financial district"   },   {     "id": 4,     "title": "social district"   } ] 

but want smth that:

"data": [       {         "id": 1,         "title": "brooklyn"       },       {         "id": 2,         "title": "financial district"       },       {         "id": 4,         "title": "social district"       } ] 

you should customize rest serializer, in controller :

public $serializer = [     'class' => 'yii\rest\serializer',     'collectionenvelope' => 'data', ];
