Is there an option to update the system fields on Jira cloud through REST API update requests (like PUT request), or there is another way to rename them?
There’s currently no way to rename system fields in Jira Cloud, through the API or otherwise. I’ve passed your feedback onto the team so it can be considered as a part of roadmap planning.
I’d love to help you still achieve your use case though, so if there’s more information you can share on exactly what you’re trying to do, we might be able to brainstorm some ways of achieving a similar result. One alternative that comes to mind is creating a custom field, which you can do through the API or UI, and name as you see fit.
Hope this helps.
Thank you Simon for the info. Do you think that the use case is possible using Java Script?
