Is there an API to get the list of devices which subscribed to a channel?

Hello,
I have 4 particle devices which are subscribed to the same event name. Say,

Particle.subscribe(“myEvent”, “myHandler”);

Is there a cloud API which takes myEvent as a parameter and returns the serial IDs of all the devices subscribed to this event name?

Regards,

Doesn’t sound like there’s one.

You could create a response that would trigger a webhook. That webhook could post the deviceID’s to a server where you could collect those responses.

pseudo code:

void myHandler(const char *event, const char *data)
{
  if(strstr(event, "census"))
  {
    Particle.publish("CountMeIn", DEVICE_ID);  // triggers webhook 
  }
  else if (strstr(event/...
}

This requires a firmware update across all my devices. I am looking for something like particle list command which can return the subscription info along with particle variables and functions list. Anyways I got the answer.

Thank you
