jobExtendedProperty() values as dynamic url Send Web Request input

[RyanDickinson1]

Has anyone been successful in using a job extended property to populate the url for a send web request step? Doesn't seem to work using it directly as the url:

Use case is a GIS analyst needs to update a definition query on a service. Analyst would use survey123 to enter the url and the new definition query. Using rest api, call remove from definition then add the new definition.

I did notice in the documentation that the step should only be configured to trusted sources.

Unfortunately the URL field does not seem to allow for Arcade expressions. But if there is a portion of a static URL that you need to populate with a dynamic value, this can be done using a path variable, which allows for Arcade inputs.

This is called by placing a ':' before the variable portion of the URL such as:

https://sample.website.com/api/:dynamicvalue/trigger

In the above example you could set an Arcade expression to populate the 'dynamicvalue' portion of the URL.
