There is no the fire endpoint

[linsdev]

There is no ability to call the fire endpoint.

I suggest to add a parameter bool norep to publish method.
After that, we can call the fire endpoint which use query parameters store = 0 and norep = true:

pubnub.publish('my-ch', 'message', storeMessage: false, norep: true);

To do this, you need to add bool norep parameter to PublishParams and publish method.
