Accessing layer (basemap) in ArcGIS Online (prompting credentials)

jkumartry1980 — Fri, 11 Feb 2022 05:49:32 GMT

Dear All,

I am developing one application using ArcGIS JS Script 4.22 . In that application I need to use basemap layer of OSI. OSI has provided a REST service link. When I use that link it asking for username and password. Basemap REST link was published in the ArcGIS online where other feature layers are published. I understand that key is needed to avoid prompting login. Could you please help me how can I create key in ArcGIS online and how I have use along with the link in the code.

Could you please assist me in this regard, since it is very urgent.

Best Regards,
K.Jayakumar

Hi,

Thanks for the reply. I tried the following code to use this layer as basemap

const imageTileLayer = new TileLayer({ portalItem: { id: "7c57414b0aad4cbc9999ad2be8d9a069" } }); const basemap = new Basemap({ baseLayers: [ imageTileLayer ] }); map = new Map({ basemap: basemap });

The particular layer was published in the ArcGIS online (Datasource URL

https://mapgenie.osi.ie/arcgis/rest/services/WM/basemap_public/MapServer) but I got this error, kindly let me know how to resolve this issue. Please note all other layers are loading without any issue.
