REST API: The group name can not be empty

[Matt Kimball]

Good Day!

I'm using Jira Server(v8.5.2) and I'm having an issue removing a user from a group via a Rest call.
I'm referencing the docs here https://docs.atlassian.com/software/jira/docs/api/REST/8.13.13/#group-removeUserFromGroup

Here is my call.

curl -D- -u "user:pass" -X DELETE -H "Content-Type: application/json" -d "{""groupname"": ""cmteam"",""username"": ""mkimball""}" "https://jira.abc.com:8443/rest/api/2/group/user"

Here is my response.

{"errorMessages":["The group name can not be empty"],"errors":{}}

Why would I be getting this error when I'm supplying a group name? Is there something wrong with the way I am supplying json data? Any advice or suggestions would be greatly appreciated!

Thank you.

Hi Matt

This endpoint requires the groupname and username as query parameters e.g.

https://jira.abc.com:8443/rest/api/2/group/user?groupname=cmteam&username=mkimball

 In your example you could do

curl -X "DELETE" -u username:password "https://jira.abc.com:8443/rest/api/2/group/user?groupname=cmteam&username=mkimball"

Worth testing this in a test environment first
