Getting Open Orders for a Symbol using Binance’s Node.js API
When working with cryptocurrency markets, it’s essential to stay up-to-date with market data. One way to achieve this is by using the Binance Node.js API. However, accessing open orders requires specific permissions and handling errors properly.
To fetch open orders for a symbol from the Binance API, you can use the getOpenOrders endpoint. Here’s how to do it:
Step 1: Set Up Your Environment
Make sure you have Node.js installed on your machine, along with the necessary packages:
npm install -g @binance/binary-data-api
This will install the Binance API package globally.
Step 2: Create a Client Credentials File
To use the getOpenOrders endpoint, you need to create a client credentials file. This file is used by the API to authenticate your requests. You can create one using your Binance account settings:
- Log in to your Binance account.
- Go to
Account >
Security>
Client Credentials.
- Click on “Create new client credentials” and select “Basic”.
- Enter a client ID and client secret (this is required for authentication).
Step 3: Write the API Call
Now that you have your client credentials, you can write the API call using Node.js:
const binaancpp = require('@binance/binary-data-api');
async function getOpenOrders(symbol) {
try {
// Set up Binance API client with client ID and secret
const client = new binaancpp.BinanceClient({
clientId: 'your_client_id',
clientSecret: 'your_client_secret'
});
// Call the getOpenOrders endpoint
const response = await client.get('openOrders', {
symbol,
limit: 10, // Return up to 10 open orders at a time
market: 'spot' // Specify market (e.g. spot for ETHBTC)
});
console.log(response.data);
} catch (error) {
console.error(error);
}
}
// Call the function with your symbol (ETHBTC in this example)
getOpenOrders('ETHBTC');
Step 4: Handle Errors Properly
When making API calls, errors can occur. To handle them properly, you should also include error handling code:
async function getOpenOrders(symbol) {
try {
// Set up Binance API client with client ID and secret
const client = new binaancpp.BinanceClient({
clientId: 'your_client_id',
clientSecret: 'your_client_secret'
});
// Call the getOpenOrders endpoint
const response = await client.get('openOrders', {
symbol,
limit: 10, // Return up to 10 open orders at a time
market: 'spot' // Specify market (e.g. spot for ETHBTC)
});
console.log(response.data);
} catch (error) {
if (error.code === 'BinanceClientError') {
const code = error.code;
const message = error.message;
switch (code) {
case 4003:
// Market is not available
break;
case 4004:
// Network error
break;
default:
console.error(message);
throw new Error(Error: ${message});
}
} else if (error instanceof Error) {
console.error(error);
}
}
}
By following these steps and including proper error handling, you can successfully fetch open orders for a symbol from the Binance API using Node.js.
