Send an automatic email when modifying attributes (of a specific field) in a service/ feature class (Portal ArcGIS Enterprise / ArcGIS Online)

[LucieSimoneau]

I would like to create a python script (or find any other way) to send an automatic email when information in one field of my feature class (service) is being modified in either ArcGIS Online or Portal.

I am not looking for sending an email when a feature is added, but rather when it's been modified.

This could potentially be accomplished with GeoEvent Server, there is an output that sends out an email if a condition is met (https://enterprise.arcgis.com/en/geoevent/latest/disseminate-and-notify/send-an-email.htm)

Setting up that condition would be the primary challenge, but once that is done you could run it on ArcGIS Online and ArcGIS Enterprise.
