Perhaps I am not reading the support documentation correctly Integrate with other apps—Survey123 for ArcGIS | Documentation but I would like to link from a Web Mapping Application to a Survey123 form and include the "SITE ID" of the Polygon the user has clicked on within the mapping application. I can link to my form but not pass the attribute.
I have used a Custom Attribute Display and thought the format should be something like
arcgis-survey123://?itemID=36ff9e8c13e042a58cfce4ad87f55d19&field:SITE_ID={SITE_ID}
The field name SITE_ID is the same in the attribute table and the form. The itemID above is just the example in the documentation.
Thanks
