Running the Adaptive response on ad-hoc mode where in I have to provide a complete url (like http://www.google.com)as parameter.
Running the Adaptive response from correlation search using Adaptive Response Actions where in I provide a complete url (like http://www.google.com) as parameter.
However on the same correlation search If I try to pass on the parameter as $url$ it fails to execute and I get failure under Notable events details.
The correlation search query is basic one which reads data from a lookup table which contains only one column called url. It returns the URL
Correlation Search query
| inputlookup demoARdata | where isnotnull(url)
Adaptive response action

However though this will work for an event, it is not the most correct way. Inside your code, you should pull and loop through all urls for all events sent into the AR in case it is somehow used on multiple events. So really you don't want to pass url at all. You want to just pull it from each event sent to the AR and execute per result.
