Hello,
Currently Jira activities for certain user are available by following request string:
activity?streams=user+IS+myname&maxResults=100&os_Basic
It is considered, that 'myname' corresponds to 'name' of REST API
rest/api/2/user/search?username=myname@com
The problem is that starting from last week, 'name' attribute is not presented at response of rest/api/2/user/, so there is no way to search activities by 'user is' criteria.
It is strongly advised to use 'accountId' attribute of user as identifier.
It there way to use Streams with 'accountId' for filtering activities by user's accountId or email?
