How to connect to https://testnet.binance.vision/api instead of main net?

[tiagosiebler]

You can try passing this in the first parameter (REST client options) in any of the rest clients:

baseUrl: "https://testnet.binance.vision"

Hi there, any way to use it for the websocket also ?

Spot API URL	Spot Test Network URL
https://api.binance.com/api	https://testnet.binance.vision/api
wss://stream.binance.com:9443/ws	wss://testnet.binance.vision/ws
wss://stream.binance.com:9443/stream	wss://testnet.binance.vision/stream

Thank you in advance !

Actually it s very easy, by using the wsUrl in the options

let _opts:WSClientConfigurableOptions={
            // api_key: this.keys.API_Key,
            // api_secret: this.keys.Secret_Key,
            beautify: true,
            // Disable ping/pong ws heartbeat mechanism (not recommended)
            // disableHeartbeat: true
           wsUrl:'wss://testnet.binance.vision/ws',
           restOptions:{
                baseUrl:'https://testnet.binance.vision'
            }
        }

in case some one have the same question

[guyhagemans]

did anything change in the meantime by any chance?

I'm trying to connect to testnet via;

    const baseUrL = (testnet ? "https://testnet.binance.vision/api" : "https://api.binance.com/api");
    const client = new MainClient({
        api_key: apikey,
        api_secret: secret,
        baseUrl: baseUrL
    });

The response I'm getting is:

I believe it is still working

I was getting 404s too but this was from using the wrong client for the operation - I was trying use the CoinMClient to get account information which won't work - you have to use MainClient(!) Here's a complete example that works at time of posting:

import {CoinMClient, MainClient, USDMClient} from "binance";
const testnet = true;
const baseUrl = (testnet ? "https://testnet.binance.vision" : "https://api.binance.com");
const client = new MainClient({
  api_key: process.env["BINANCE_API_KEY"],
  api_secret: process.env["BINANCE_API_SECRET"],
  baseUrl
});

// Get the account balance
client
    .getAccountInformation()
    .then((result) => {
        console.log('getSymbolOrderBookTicker result: ', result);

        console.log("time to die!");
        process.exit()
    })
    .catch((err) => {
        console.error('getSymbolOrderBookTicker error: ', err);
    });

Seems MainClient.getBalances() is using /sapi endpoints and when we are connecting to testnet , is not working..
