Now I am writing a Confluence plugin, it needs Jira issue data such as a custom field value which is a checklist. For now I can use Jira rest api /rest/api/latest/issue/(issueID) to get all the other data. but for the checklist it only shows all value without check status.
"customfield_*":["US-English","Arabic","Arabic/English","B-Portuguese","Benelux","Bulgarian","Bulgarian/English","C&L Croatian"]
