# Add Feature To Layer

`POST /api/v1/table/{layer_id}/features`

Add a complete GeoJSON feature to a layer.

## Request body

    - unknown
  - `properties` object
  - `layer_id` string, uuid, required
  - `source_feature_id` string, nullable

## Response `200`

Successful Response

- FeatureAddResponse — Response model for adding a feature. ``data_version`` is the layer's new version after a successful add (bumped in the same transaction). None on failure since a failed create does not bump. The FE uses this to rotate the tile URL's ``?v=``.
  - `success` boolean, required

  - `feature_id` string, nullable
