stackdriver Request contains an invalid argument

Question

I'm studying about Google Cloud Platform.

In this stackdriver projects.groups.members.list I'm trying to get member's list in stackdriver's group.

when I command this code in above link,I get this error.

GET https://monitoring.googleapis.com/v3/projects/{my_project}/groups/{my_group}/members?key={YOUR_API_KEY}

error :

{  
  "error": {
    "code": 400,   
    "message": "Request contains an invalid argument.",   
    "status": "INVALID_ARGUMENT"  
  } 
}

my_project and my_group is correct, and there is no other argument, is there any problem?

Answer 1

I found that {my_group} is not alphabetical string like my_group,

but integer string like 12345678956.

in this projects.groups.list you can find your group_id by excuting APIs Explorer.
