The examples I've found are either incomplete or don't work with the current API. Can someone please help me?</P><P>Thanks!</P><P>&nbsp;</P> Mon, 04 Nov 2024 16:54:06 GMT https://community.esri.com/t5/python-questions/how-can-i-create-a-hosted-feature-layer-from/m-p/1555142#M73137 john_cartwright_noaa 2024-11-04T16:54:06Z https://community.esri.com/t5/python-questions/how-can-i-create-a-hosted-feature-layer-from/m-p/1555639#M73139 <P>Try this.</P><P>&nbsp;</P><LI-CODE lang="python">from arcgis.gis import GIS from arcgis.features import FeatureLayerCollection # Connect to your GIS gis = GIS("https://www.blah.com", "username", "password") # Step 1: Create an empty feature service service_name = "awesome_python" empty_service_item = gis.content.create_service(name=service_name, service_type='featureService') feature_layer_collection = FeatureLayerCollection.fromitem(empty_service_item) # Step 2: Define the feature layer schema (fields, geometry type, spatial reference, etc.) layer_definition = { "layers": [ { "name": "MyFeatureLayer", "geometryType": "esriGeometryPoint", # Change to Polyline, Polygon as needed "fields": [ { "name": "ObjectID", "alias": "ObjectID", "type": "esriFieldTypeOID" }, { "name": "Name", "alias": "Name", "type": "esriFieldTypeString", "length": 50 }, { "name": "Description", "alias": "Description", "type": "esriFieldTypeString", "length": 255 }, { "name": "Value", "alias": "Value", "type": "esriFieldTypeDouble" } ], "objectIdField": "ObjectID", "globalIdField": "", "displayField": "Name", "typeIdField": "", "spatialReference": {"wkid": 4326} # WGS 84 } ] } # Step 3: Add the layer to the feature service feature_layer_collection.manager.add_to_definition(layer_definition) print("Feature layer created successfully!")</LI-CODE> Tue, 05 Nov 2024 23:06:11 GMT https://community.esri.com/t5/python-questions/how-can-i-create-a-hosted-feature-layer-from/m-p/1555639#M73139 TonyAlmeida 2024-11-05T23:06:11Z https://community.esri.com/t5/python-questions/how-can-i-create-a-hosted-feature-layer-from/m-p/1556119#M73145 <P>Thanks - just what I needed!</P><P>&nbsp;</P> Wed, 06 Nov 2024 23:29:49 GMT https://community.esri.com/t5/python-questions/how-can-i-create-a-hosted-feature-layer-from/m-p/1556119#M73145 john_cartwright_noaa 2024-11-06T23:29:49Z https://community.esri.com/t5/python-questions/how-can-i-create-a-hosted-feature-layer-from/m-p/1556422#M73150 <P>Awesome!</P> Thu, 07 Nov 2024 17:57:34 GMT https://community.esri.com/t5/python-questions/how-can-i-create-a-hosted-feature-layer-from/m-p/1556422#M73150 TonyAlmeida 2024-11-07T17:57:34Z
