    Publish from server

    Use the following POST request to publish a message from your server.

        "key": "API_KEY",

        "message": "Hello world!"

    See code examples for this request in PHP, NodeJS, Ruby, Python, Java and Go in our official documentation.

    Client to client communication

    You can enable C2C communication for your API key from your PieSocket account and then use the send method of the Channel object to send messages directly from a client.


    To send JSON, use following code:


    Make sure you are calling send method after connection has been made i.e on('open', callback) has been called.
