Atlassian Update - 2 September 2019 Dear users, Createmeta REST endpoint is commonly used when Atlassian products (Confluence, Bitbucket, and others) create issues in Jira. It might also be used by 3rd party apps. The main problem with the old createmeta endpoint is that it is duplicating values in the response. Although the response can be filtered, due to the design of the endpoint it is very easy to cause downtime. We have been working on a fix for this problem most of the solutions made the endpoint harder and more complex to use. So we decided to deprecate the old endpoint and introduce new endpoints that will replace the old createmeta endpoint. We also added a new dark feature to disable the old endpoint. The new endpoints will return projects, issue types and fields separately. You can find more details here . Changes will be released with Jira 8.4.0 and the old createmeta will be removed in Jira 9. We suggest anyone who is using the old endpoint to migrate to the new endpoints. Since this endpoint is used by other Atlassian products, they will be updated also. We are planning the changes and we will update this ticket with the compatible version of each product. Sincerely, Celebi Murat Jira Server Development
