Subscribing & Unsubscribing

Once connected and authenticated to the sFOX WebSocket API you can subscribe to various feeds by using the subscribe or unsubscribe command.

These commands should be JSON with the following properties:

Property	Type	Command
type	string	Command you are sending to the websocket (subscribe or unsubscribe)
feeds	string[]	List of the feeds that should be subscribed/unsubscribed to

NodeJS

const subscribeMsg = {
  type: 'subscribe',
  feeds: ['ticker.sfox.btcusd']
}
ws.send(JSON.stringify(subscribeMsg));

...

const unsubscribeMsg = {
  type: 'unsubscribe',
  feeds: ['ticker.sfox.btcusd']
}
ws.send(JSON.stringify(unsubscribeMsg))

Python

subscribe_msg = {
    "type": "subscribe",
    "feeds": ["ticker.sfox.btcusd"],
}

await ws.send(json.dumps(subscribe_msg))

...


unsubscribe_msg = {
    "type": "unsubscribe",
    "feeds": ["ticker.sfox.btcusd"],
}

await ws.send(json.dumps(unsubscribe_msg))
