Mark a custom field unique in JIRA Server

[Darshan Chhajed]

 I have created a custom reference field in JIRA Server whose value is getting populated via API. I want this field should hold a unique value across the entire JIRA, so I am thinking to mark it as unique. How can I do this?

mmm... you say the field is being populated via API, so you should build your request accordingly. What's the nature of this unique custom field you want to create?

Without too much detail because I'm no expert whatsoever I'd say you'll need to first check whatever you need related to the "uniqueness" of your field (via get request) and then build your put or post or whatever request based on that result.
