- create a string variable: strEmailList
- send an http request: _api/web/sitegroups/getbyname(‘group name’)/users
- to get the results: add -> control -> for each
the output: body(‘GetGroup’)[‘d’][‘results’] - get the user email – items(‘LoopUsers’)[‘Email’]
and build the strEmailList
- add a ‘;’ after each user to strEmailList
- use the result to send email.
