Input Parameter: Get hosted feature layer ID?

[SH_DH]

Hi there - I'd like to have a script input parameter that ultimately returns the ArcGIS Online item ID for a hosted feature layer for updating that item in a webmap.  Using a 'feature layer'  parameter returns the REST URL of that hosted layer. 

Using REST would seemingly require the user to have to enter a name/password and generate a token just to get the ID of that hosted feature layer.  Is there a way around this?

You can use the Featureclass input (selecting it from the Portal content in catalog), then in the code you can get the item Id:

import arcgis
from arcgis.features import FeatureLayer

# you can probably use the existing connection from pro if they are already signed in.
gis = arcgis.GIS("https://<domain>.maps.arcgis.com", client_id="AppId")

# this would be the feature service address that is from the input parameter
fs_url = 'https://services9.arcgis.com/435tk5oo45nwo/arcgis/rest/services/trips/FeatureServer'

# get the item using the url
in_service = FeatureLayer(fs_url)

props = in_service.properties
# print item id
arcpy.AddMessage(props.serviceItemId)

that's exactly what I was hoping for - thank you!
