Getting started

Follow the simple steps below to start sending and receiving messages/events in real-time with the managed WebSocket API.

API credentials

You can get your API key and API secret from here.

Connect to the server

For web-applications, there is no need to install any library or dependency in your project, WebSocket is supported by default in all modern browsers.

var apiKey = 'oCdCMcMPQpbvNjUIzqtvF1d2X2okWpDQj4AwARJuAgtjhzKxVEjQU6IdCjwm'; //Demo key, Change this to yours
var channelId = 1; 
var piesocket = new WebSocket(`wss://demo.websocket.me/v3/${channelId}?api_key=${apiKey}&notify_self`);

You can also use the API with: Android, iOS

You are now subscribed to channel 1, read more about the WebSocket API and supported parameters in the WebSocket API section.

Listen for incoming messages

When a server or another client sends a message/event, piesocket.onopen will be fired. Let's write some code to handle this event.

piesocket.onmessage = function(message) {
    alert(`Incoming message: ${message.data}`);
}

Publish a message

You are subscribed to channel 1, it's time to send a message.

Publishing from a server

Here is a PHP example

$curl = curl_init();

$post_fields = [
    "key" => "oCdCMcMPQpbvNjUIzqtvF1d2X2okWpDQj4AwARJuAgtjhzKxVEjQU6IdCjwm", //Demo key
    "secret" => "d8129f82f8dd71910aa4a7efa30a7297", //Demo secret
    "channelId" => 1,
    "message" => "Hello world!"
];

curl_setopt_array($curl, array(
  CURLOPT_URL => "https://www.piesocket.com/api/publish",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => json_encode($post_fields),
  CURLOPT_HTTPHEADER => array(
    "Content-Type: application/json"
  ),
));

$response = curl_exec($curl);

See examples in: NodeJS, Ruby, Python, Java, GO, Shell (curl, wget)

Publishing from a client

It is possible to publish from a client too, and you can send messages/events to other connected peers using JavaScript from your browser/client without a server.

piesocket.send({
    "type": "event",
    "name": "test-event",
    "message": "Hello world!"
});

or just this:

piesocket.send("Hello world!");

This will only work when C2C (Client-to-client) communications are enabled for your API in API settings. C2C is enabled by default (for backward compatibility) and you MUST disable it for better security.

Please note that when you enable C2C, anyone with your API KEY can publish messages/events to your channels. The SECRET_KEY will no longer be required.

This is why we recommend you disable C2C for your API key and only use the server-side code to publish messages wherever possible.

Publishing from our website

If C2C is enabled (not recommended) for your API key, You can use our WebSocket tester to publish and receive messages.
