Custom URLs in a Custom Attribute Dispay Pop-Up

[BrianShepard]

We need to create hyperlinks in pop-ups that deep link to internal applications.  Why does ArcGIS Online allow me to configure a hyperlink with a custom URL, but then changes the protocol to http:// when I save?

I need to be able to create a clickable link in a pop-up with cwsphoto://{Field1}/{Field2}?{Field3}&{Field4}.  Not all URLs use http protocol.

Please refer to the following link on supported HTML. This is done to prevent any HTML injection/security vulnerabilities.

• HTML tags not listed in the table are not supported and will be filtered out. 
• Allowed protocols for href and src are https, http, tel, and mailto.

Hope that helps!

This has been a recurring issue with various ESRI apps and results in huge inefficiencies for our staff.  We have two custom iOS applications that are sideloaded onto devices using a MDM.  Our apps and URI schemes have been validated by Apple.  How do we go about getting those schemes whitelisted by ESRI?

Thanks,
