Groups API - manually syncing group membership?

You seem to be right on this – you cannot access group resources with the ID number, only the name.

                type: type,
                order: order,
                asc: params[:asc],
                filter: filter
              )
            )
          end
          
          def show
            respond_to do |format|
              group = find_group(:id)
          
              format.html do
                @title = group.full_name.present? ? group.full_name.capitalize : group.name
                @description_meta = group.bio_cooked.present? ? PrettyText.excerpt(group.bio_cooked, 300) : @title
                render :show
              end
          
              format.json do
                groups = Group.visible_groups(current_user)
                groups = groups.where(automatic: false) if !guardian.is_staff?

The ID referenced here is not an ID, but the name, per

                  custom_fields = DiscoursePluginRegistry.editable_group_custom_fields
                  default_params << { custom_fields: custom_fields } unless custom_fields.blank?
                end
          
                default_params
              end
          
            params.require(:group).permit(*permitted_params)
          end
          
          def find_group(param_name, ensure_can_see: true)
            name = params.require(param_name)
            group = Group.find_by("LOWER(name) = ?", name.downcase)
            guardian.ensure_can_see!(group) if ensure_can_see
            group
          end
          
          def users_from_params
            if params[:usernames].present?
              users = User.where(username_lower: params[:usernames].split(",").map(&:downcase))
              raise Discourse::InvalidParameters.new(:usernames) if users.blank?

It probably makes sense to refactor the /g/<group-name> route to match how we now handle topics and categories. Something like /g/<group-name>/<id> or /g/patrons/41 and allow /g/41 to function the same way.

Until we fix that up, though, it seems the only way to accomplish what you’re looking for is:

Storing the group name alongside the id
Hitting g/<group-name>/members.json with a GET request to get the members
Loop through those to delete each so you can re-sync.
