Hi Atlassian Team,
I‘m developing an service system on JIRA,I need add some users to some groups,the API tells that I should use API“add user to group”,but the parameter——’accountId‘ is required,where should I get it? I’m try to use API“get accountid”, but the parameter——"username" is required, where can I get it?
And I try to use ‘query’,for example:

But I still cant get it

Thanks.
