Hi there,
According to this post: https://confluence.atlassian.com/jiracore/createmeta-rest-endpoint-to-be-removed-975040986.html, the /createmeta endpoint will be replaced with the solution described in the post.
My approach so far:
I am currently using a script which uses the endpoint:
/rest/api/2/issue/createmeta?projectKeys=%s&expand=projects.issuetypes.fields
, to extract the issuetypes fields.
Following the solution in the post (see link above), I changed my request to:
/rest/api/2/issue/createmeta/{projectId}/issuetypes
, and for the projectId, I use the id number I get from the request:
/rest/api/2/project
In both request, I use Basic Authorization.
Additional info:
I also used version 3 of the API but still not success. Everytime I get a 404 back. My client is using the Jira Cloud. I also tried the request with:
/rest/api/2/issue/createmeta/{projectId}/issuetypes/{issueId}
, but this also did not work.
Thanks in advance for your help/ideas
