NextGIS Web - HTTP API

For components that provide API:

resource — resources management
feature_layer — vector layer features management
feature_attachment — managing feature attachements
fjle_upload, style, wfs/wmsserver etc.

Example: feature_layer, resource

/api/resource/{id}/feature/{fjd} GET,DELETE,PUT
/api/resource/{id}/feature/ GET,POST
/api/resource/{id} GET,PUT,DELETE
/api/resource/{id}/permission GET
