Using Python to identify Map objects used in Esri ArcGIS Enterprise Portal or AGOL Web Applications?

Hi!
I'm trying to list the feature layers shown in each map from every web application, dashboard, and storymap on my Enterprise Portal. Is there a way to retrieve all the map objects that belong to an app? Something like this, maybe?:

from arcgis.gis import GIS from arcgis.mapping import WebMap gis = GIS(url='https://myesriportal.org/portal', username='admin', password='PUT_PASSWORD_HERE') webapp_items = gis.content.search(query=f"type:Web Mapping Application", max_items=10000) webapp_items += gis.content.search(query=f"type:Dashboard", max_items=10000) webapp_items += gis.content.search(query=f"type:StoryMap", max_items=10000) #print the web app title, web map title, and layer name for webapp_item in webapp_items: for webmap_item in webapp_item.content.webmaps: # Does something like this exist? webmap_obj = WebMap(webmap_item) for layer in webmap_obj: print(webapp_item.title, webmap_item.title, layer.title)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thanks in advance for any suggestions!

I don't think there's an easy way to pull a list of webmaps from an app, especially given the numerous types of apps you could be dealing with - EXB, WAB, StoryMaps, Dashboards, etc.

One way might be to do this:

Scan your portal for webmap items and cache their Item IDs in a set
Scan your portal for apps and for each, do the following:
- Get the item's JSON definition using get_data()
- Use regex to look for any Item IDs in the JSON
- Anywhere you find an Item ID, check it against your set, and if you get a hit, print it out

I've used this approach when looking for layers referenced by webmaps and it worked well, I haven't tried it with the app-webmap scenario.

I can imagine at least two scenarios where I don't think this would work and you'd need some extra logic:

An app that uses an external organization's webmap
Embedded content panels that include a URL but not an Item ID

Edit to Add - Re-reading your code I noticed you're not just printing out the webmap Item IDs but also the layer IDs, so you'd probably want to cache those details along with the webmap IDs.

I still need to complete the section about pulling data sources for apps; but this code goes through all maps and creates an inventory all layers and adds them to a hosted table (feature layer variable is warehouse_maps_svc_lyr)

#Build Map Inventory table - Maps and associated layers from arcgis.mapping import WebMap from arcgis.features import FeatureSet import pandas as pd wm_items = gis.content.search("*", item_type="Web Map", max_items=500) print("This ArcGIS Online Organization contains {} web maps.".format(len(wm_items))) map_count = 0 layer_count =0 for webmap_item in wm_items: map_count = map_count + 1 print("---------------------") print("Map ",map_count, " of ",len(wm_items)) ago_map_id = webmap_item.id print("Map ID:",ago_map_id) map_title = webmap_item.title map_owner = webmap_item.owner print("Map Title: ",map_title) #convert to Map wmItem = gis.content.get(ago_map_id) webmap = WebMap(wmItem) try: layers = webmap.layers tables = webmap.tables except Exception as e: print("Error setting layers and tables") try: # Export Feature Services/Tables if len(layers) > 0: for layer in layers: layer_count = layer_count + 1 if layer.layerType =="GroupLayer": for g in layer.layers: lyr_url = g.url lyr_id = g.id lyr_name = g.title print("Group Layer Name:",lyr_name) print("Group Layer ID:",lyr_id) print("Group Layer URL:",lyr_url) layer_data = { 'ago_map_id': ago_map_id, 'map_title':map_title, 'map_owner':map_owner, 'ago_layer_id': lyr_id, 'layer_title':lyr_name, 'layer_url':lyr_url} df = pd.DataFrame(layer_data, index=[0]) feature_set = FeatureSet.from_dataframe(df) result = warehouse_maps_svc_lyr.edit_features(adds=feature_set) else: lyr_url = layer.url lyr_id = layer.id lyr_name = layer.title print("Layer Name:",lyr_name) print("Layer ID:",lyr_id) print("Layer URL:",lyr_url) layer_data = { 'ago_map_id': ago_map_id, 'map_title':map_title, 'map_owner':map_owner, 'ago_layer_id': lyr_id, 'layer_title':lyr_name, 'layer_url':lyr_url} df = pd.DataFrame(layer_data, index=[0]) feature_set = FeatureSet.from_dataframe(df) result = warehouse_maps_svc_lyr.edit_features(adds=feature_set) if len(tables) > 0 : for table in tables: print("Table") layer_count = layer_count + 1 lyr_url = table.url lyr_id = table.id lyr_name = table.title print("Table Name:",lyr_name) print("Table ID:",lyr_id) print("Table URL:",lyr_url) layer_data = { 'ago_map_id': ago_map_id, 'map_title':map_title, 'map_owner':map_owner, 'ago_layer_id': lyr_id, 'layer_title':lyr_name, 'layer_url':lyr_url} df = pd.DataFrame(layer_data, index=[0]) feature_set = FeatureSet.from_dataframe(df) result = warehouse_maps_svc_lyr.edit_features(adds=feature_set) except Exception as e: print("Error getting properties") print("\t{}\n\t{}".format("Map Count: " + str(map_count), "Layer Count: " + str(layer_count)))
