https://community.esri.com/t5/arcgis-online-questions/update-layer-definition-in-webmap-using-arcgis-api/m-p/1619069#M64888 <P>Can someone explain how to access and update the contents of webmaps in version 2.4+ of the ArcGIS API for Python? I used to be able to use get_data() to access the operational layers and sublayers using the layers property and then use update() to update the original json file, but I can't seem to find how to do this with the new arcgis.map and arcgis.layers modules. Specifically I'm looking to configure popups and reorder/hide field names in the layer attribute tables. My maps feature Map Image Layers that contain multiple sublayers. Any help is much appreciated.</P><P><a href="https://community.esri.com/t5/user/viewprofilepage/user-id/374806">@PeterKnoop</a>&nbsp;<a href="https://community.esri.com/t5/user/viewprofilepage/user-id/417766">@Clubdebambos</a>&nbsp;</P> Wed, 28 May 2025 20:06:35 GMT ClintonBradley 2025-05-28T20:06:35Z https://community.esri.com/t5/arcgis-online-questions/update-layer-definition-in-webmap-using-arcgis-api/m-p/1619069#M64888 <P>Can someone explain how to access and update the contents of webmaps in version 2.4+ of the ArcGIS API for Python?

Hoping this isn't the requirement going forward.</P> Wed, 28 May 2025 20:31:05 GMT https://community.esri.com/t5/arcgis-online-questions/update-layer-definition-in-webmap-using-arcgis-api/m-p/1619088#M64890 ClintonBradley 2025-05-28T20:31:05Z
