How to find the symbol name for binance web socket api using javascript
The Binance website API Provides Real-time Data Feeds for Various Cryptocurrencies and Markets. One of the Essential Steps in Utilizing This API is to Subscribe to Specific Symbol Names, which Ich Enable You To Receive Updates About the Price And Market Activity of a Privular Cryptocurrency or Asset.
In this article, we will guide you through the process of finding the symbol name for the binance websocket api using javascript.
Prerequisites
Before Diving Into The Code, Ensure That You Have:
- Installed the
wspackage in your project (npm install ws) to handle web socket connections.
- Created a New Websocket Connection to Binance’s Websocket API by Visiting [WSS: //Dex.binance.org/api/ws] (http: // wss: //dex.binance.org/api/ws).
- Set up an account on binance and obtained the
api secretKey, which is request for authenticating with the websocket API.
Connecting to Binance website API
The code provid uses a web socket connection to subscriber to specific symbol names. Here’s How It Works:
`Javascript
Conn Conn = New Websocket (“wss: //dex.binance.org/api/ws”);
Conn.Onopen = function (possibly) {
console.log (connected to binance web socket api at $ {possibly data.url} `;
};
In this Example, wss: // dex.binance.org/API/WS is the url of the binance web socket API. When The Connection is Established (i.e., an open event occurs), it logs a message indicating the successful connection to the api.
Subscribing to Symbol names
To Subscribe to Specific Symbol Names, You can use the Subscrobe () Method Provided by the Websocket API. The Subscribe () Method Takes Four Arguments:
- Method : This specifications The Operation to Perform on the Data Received from the API.
- topic : This defines the topic or ticker to which you want to subscribe.
- Symbols : This is a comma-soparated list of symbol names (E.G., “bnb_btcbtc”).
Here’s an Example Subscription Request:
`Javascript
Const Subscribequest = {
Method: “Subscribe”,
Topics: [“Cline_1H”, “Kline_4H”],
Symbols: [“bnb_btcbtc”]
};
Conn.send (json.stringify (subscribequest));
`
In this code snippet, we define a subscribequest object with the specific parameters. The Subscribe () Method Sends A Request to Binance’s Websocket API With the Subscription Details.
Handling data
Once You’ve Subscribed to Specific Symbol Names, You’ll Receive Updates About the Price and Market Activity of Those Symbols in real-time. To Handle This Data, You Can Use Event Listeners For Websocket Events (E.G., Open,Close, Message ').
For Example:
Javascript
conn.onmessage = function (possibly) {
Constmentage = possibly data;
console.log (message);
};
`
This code sets up a listener for any incoming messages from the websocket API. When A Message is Received, IT Logs the Data To The Console.
Conclusion
Finding the Symbol Name for Binance’s Website API Using Javascript Involves Connecting to the API, Subscribing to Specific Symbol Names, and Handling Updates About the Price and Market Activity of Those Symbols in real-time. By following this guide and experimenting with the provid code snippets, you’ll be able to utilize binance’s web socket api to build robust and efficient applications.
