is_team_folder returns false for team folders

chrismcfarling There are a few ways you can get the team space ID. For instance, you can get it from the 'root_info' returned by /2/users/get_current_account:

curl -X POST https://api.dropboxapi.com/2/users/get_current_account \
    --header "Authorization: Bearer <redacted>"

# {
# <redacted>
#   "root_info": {
#     ".tag": "team",
#     "root_namespace_id": "1990815600",
#     "home_namespace_id": "1990696960",
#     "home_path": "/db test"
#   }
# }

Or, if you're using a Dropbox Business API app with the team member file access permission, you can get it from /2/team/team_folder/list[/continue] or /2/team/namespaces/list[/continue]:

curl -X POST https://api.dropboxapi.com/2/team/team_folder/list \
    --header "Authorization: Bearer <redacted>" \
    --header "Content-Type: application/json" \
    --data "{}"

# {
#   "team_folders": [
#     {
#       "team_folder_id": "1990815600",
#       "name": "<redacted>",
#       "status": {
#         ".tag": "active"
#       },
#       "is_team_shared_dropbox": true,
#       "sync_setting": {
#         ".tag": "default"
#       },
#       "content_sync_settings": []
#     }
#   ],
# <redacted>
# }

curl -X POST https://api.dropboxapi.com/2/team/namespaces/list \
    --header "Authorization: Bearer <redacted>" \
    --header "Content-Type: application/json" \
    --data "{}"

# {
#   "namespaces": [
#     {
#       "name": "<redacted>",
#       "namespace_id": "1990815600",
#       "namespace_type": {
#         ".tag": "team_folder"
#       }
#     },
# <redacted>
#   ],
# <redacted>
# }

I recommend reading the Namespace Guide as it goes over some of these topics.
