using the REST API i did that with the JavaScript SDK :
yam.platform.request({
url: "users/in_group/2490226",
method: "GET",
});
I retrieved users but I can't see which one is an admin
Can I retrive the admins of a group using the REST API?
If you use the group/{group id}/members.json call, the list of returned users will include the "is_group_admin" field.
Here is an example: https://www.yammer.com/api/v1/groups/4767132/members.json
4767132 is your groupID. The json response will include a list of users where a single user record looks like this:
{
"type": "user",
"id": 1526232831,
"name": "yam5dummy",
"state": "active",
"full_name": "yam5dummy",
"job_title": null,
"network_id": XXXXXX,
"mugshot_url": "https://mug0.assets-yammer.com/mugshot/images/48x48/no_photo.png",
"mugshot_url_template": "https://mug0.assets-yammer.com/mugshot/images/{width}x{height}/no_photo.png",
"url": "https://www.yammer.com/api/v1/users/1526232831",
"web_url": "https://www.yammer.com/XXXXX.com/users/1526232831",
"activated_at": "2014/10/01 16:12:03 +0000",
"auto_activated": false,
"stats": {
"following": 1,
"followers": 1,
"updates": 0
},
"email": "yam5.dummy@XXXXX.com",
"is_group_admin": true,
"group_member": {
"state": "approved"
}
},
Notice the "is_group_admin": true,
