Public Usage
You need to import ws library and create a connection with Fine Exchange, For e.g
const WebSocket = require('ws');
const API_URL = 'https://api.fine.exchange'
// Public connection
const publicSocket = new WebSocket(`${API_URL}/stream`);
Private Usage
You need to authenticate through the api either using Bearer token or with API key and Secret which you can obtain from the guide
API Expires field just used to define the validity of the connection.
const WebSocket = require('ws');
const API_URL = 'https://api.fine.exchange'
// Bearer Token
const privateSocket = new WebSocket(`${API_URL}/stream?authorization=${BEARER_TOKEN}`);
// HMAC Authentication
const privateSocket = new WebSocket(`${API_URL}/stream?api-key=${API_KEY}&api-signature=${API_SIGNATURE}&api-expires=${API_EXPIRES}`);
// Bearer Token
privateSocket.send(
JSON.stringify({
op: 'auth',
args: [{
authorization: BEARER_TOKEN
}]
})
);
// HMAC Authentication
privateSocket.send(
JSON.stringify({
op: 'auth',
args: [{
'api-key': API_KEY,
'api-signature': API_SIGNATURE,
'api-expires': API_EXPIRES
}]
})
);
