How do I search projects based on their settings/configuration?

[Test Man Dan]

Ok, so here's my predicament: 

I'm trying to turn off the "Allow Unassigned Issues" setting in Jira's configuration. I've managed to use JQL to search for all the outstanding unassigned issues and assign them, that's fine. 

However, I am still being blocked by several projects that have the Default Assignee set to "Unassigned". Now, I've gone through what I think are all the projects (We have quite a sizeable catalogue, so this is no mere task), but there are apparently still 7 projects that have this flag set. 

Is there a way that I can easily find these projects so that I can change this flag to be able to disable Unassigned issues all together?

With the REST API,

a bit of code and in 5 min you find all the projects with default assignee set to "Unassigned"

I'm a bit new to the back-end of Jira in this sense, How would I access the APIs? A google search is not making it very clear.

Here is documentation for the REST API:

https://docs.atlassian.com/jira/REST/server/

and you need this section of the page:

https://docs.atlassian.com/software/jira/docs/api/REST/7.6.1/#api/2/project

Is there not a way to achieve this using JQL?

[Nir Haimov]

Sorry, but no...

[Test Man Dan]

Damn. I'll have a look down the API route. 
Is it covered on the Jira Training then?

[Nir Haimov]

No.

You just have to know how to use REST API (generally, it's the same with any REST API).

Once you know how to use REST API, and you have the address (which i sent you before) than you are good to go.

In the document i sent you there is a guide in the beginning that may help you.
