REST API Leverage Existing Field Extractions

New Member


I've run into an issue while working with the Splunk Rest API, specifically when trying to leverage extracted fields.

Within the Splunk App my data lives in I have the following regular expression as a field extraction for sendmail QID


This works as expected in the GUI for myself and users of the application.

However, when attempting to leverage the "QID" field in a REST API Call with the following parameters (x-www-form-urlencoded. I'm showing this as a dict as I use python for my calls.), there is no QID field available to me.



POST to services/search/jobs


"rf" : "QID",

"adhoc_search_level" : "verbose",

"search" : "search index=sec_email sourcetype=<mysourcetype> earliest=@d | fields QID, msgid | search msgid=\"<my_message_id>\""


I've confirmed that I receive results here, but QID field is not available.

My question here is:

Is there a parameter I am missing to leverage pre-existing field extractions from the Splunk App, or am I going to need to use rex to re-extract (this is what I am doing now, but it's less than ideal).


Thank you!
