To filter the create messages you will need to put the users in a group that is scoped to their user instead of the resource. This can be accomplished by implementing the method _group_name(self, action, id=None) on your binding class to return a string unique to that resource and user. Here’s a rough idea

from channels_api.bindings import ResourceBinding

class MyBinding(ResourceBinding):

     def _group_name(self, action, id=None):
           if action == "create":
                  return "{}-{}-{}".format(self.model_label, action, user_id)

Hi there, what version of channels are you using? Can you share a form of your binding class? Thanks
