How do I create an issue (REST API) without a security level if there is a default security level?

[Tomas Deceuninck]

So I am trying to create an issue that has the "None" security level.

In the gui I can just select "None" from the drop down and it creates the issue without a security level.

But when I leave out security level in my api request it sets the default security level.

How should I describe the security field in my request so it will not be set?

I've not tried this, but I think sending it a null or empty security level should do it

"none" is a placeholder word Jira shows to the user instead of the more unclear "empty line in a dropdown" which confuses people.  It  represents an empty field (no data in the jiraissue table for system fields, or no line in customfieldvalue if it's a custom field) rather than the string "none"

Wonderful!

when you explicitly set it to "null" it works

FYI: Setting name or id to empty string does not work.

Ah, great, thanks for the update!

Thanks for this info.

Note, it's important to set "security":null, not "security":{"id":null} or "security":{"name":null}. The latter two will result in an error. 
Also, set it to null and not "null". That will result in an Internal Server Error.

Thos are the lessons I learnt ;-)
