I have a map built using ArcGIS JS API v4.8. The map has a basemap and FeatureLayer that are both secured by a custom API and a server-side proxy.

I'm looking to make use of the Printing widget, but if I have the private FeatureLayer displayed, it fails to work, and if I switch that layer off it provides a print out but it doesn't show the custom basemap (so it's effectively just a blank page).

Is there a way to use the Printing widget even if layers/basemaps are not publically accessible? I presume the issue here is the PrintTaskUrl that's hosted by Esri can't access my private layers? Does anyone have any suggested workarounds for this at all?

  • Are you using the built-in IdentityManager (developers.arcgis.com/javascript/latest/api-reference/…) to authenticate access to your secured layer?

  • We're not, no - it's a custom authentication layer powered by Azure API Manager. One layer is stored in AGOL but the other is hosted internally.

To print secure layers, the preferred way is probably to have your own print service, and embed the authentication in it.

See https://enterprise.arcgis.com/en/server/latest/create-web-apps/windows/printing-maps-that-contain-secured-services.htm for more info.
