Add custom geoprocessing service to WebApp Builder in ArcGIS Online

[Kbray_gis_]

I'm currently trying to add a geoprocessing service to WebApp Builder in ArcGIS Online.

I followed the following steps here: 

How To: Publish a Custom Print Service with Embedded Credentials from ArcGIS pro to a Stan (esri.com...

However when I add the rest endpoint for the tool into the print widget, it prompts for user credentials, even though they are embedded within the tool.

The geoprocessing service is in a standalone ArcGIS Server version 11.1, the tool was published from ArcGIS Pro 3.x.

The geoprocessing service security setting is set to private, which is why i think it prompts for login, but I would of thought that because I've embedded credentials that it would not prompt,

If I set the service security setting to public in arcgis server, the print widget works fine, however when it is set to private it prompts, is this expected behaviour? is there a way around it?

Has anyone else came across this, or been able to add a custom print service from a standalone ArcGIS Server into WebApp Builder in ArcGIS Online so users can use custom print templates/layouts.

Thanks in advance,

Kind regards

Have you configured a valid SSL certificate with your ArcGIS Server 11.1? 

To prove it works within your network, visit this page: https://developers.arcgis.com/javascript/latest/sample-code/widgets-print/

edit the code to amend portalItem and printServiceUrl to point towards your own services. Copy the code and run it in a local web server (VS code live server is great).

If you're still seeing issues with a valid certificate, consider importing the intermediate and root certificate from ArcGIS Online to your ArcGIS Server 11.1

That is correct. Since your print service itself is secured, your web app challenges you for credentials to access that.

but I would of thought that because I've embedded credentials that it would not prompt,

Embedded credentials is for print service to use while accessing secured map/feature/image and other secured services.

If I may, I'm curious to know why are you embedding credentials within a print service. Most of the scenarios, you don't need to go in this route.

Thanks for getting back to me @TanuHoque and @A_Wyn_Jones, 

@TanuHoque thank you for clarifying that for me, I wasn't sure if embedding credentials was for accessing secure services in the map, or if it was for the actual tool itself,

I wanted to have the print service/tool set to private, as I didn't want it to be public so if someone outside of the organization was to come across it, they could utilize it, so I thought if I set it to private then that would solve that problem, but then it would prompt organization users to login, but I didn't want users in our organization to need to login when using it, as that would be a bit annoying having to do that all the time,

So, I thought that embedding credentials would solve that, but after a bit of trial and error, it doesn't seem like that is what the intention is for embedding credentials,

@A_Wyn_Jones thanks for sending through the information, I hadn't looked into going down creating a custom print widget as at the moment its a bit out of skill, I was just publishing a web tool, but maybe I could look into that could look at doing that,
