Ethereum: Nodejs, Binance API : Timestamp for this request is outside of the recvWindow
Ethereum Node.js Integration with Binance API: Fixing the “Timestamp” Error
As a developer working with Ethereum nodes and Binance API, you are probably familiar with the importance of keeping data in sync between them. However, issues can arise when integrating these components for various reasons. In this article, we will look at the “Timestamp” error that is causing problems for our node.js applications, especially when using the Binance API.
recvWindow Problem
When making requests to the Binance API using Node.js, it is essential to ensure that your request is timestamped. It is in the recvWindow. recvWindow represents the minimum amount of time (in milliseconds) that the client should wait before sending another request. This concept is crucial when managing competing requests.
Timestamp Error: A Brief Context
A timestamp error occurs when the current timestamp of the request exceeds the recvWindow. This can happen due to various factors, such as:
- Network Latency: A sudden increase in network traffic or packet loss can cause timestamps to become out of sync.
- Time Zone Differences: Timestamp discrepancies can occur when working with APIs that operate in different time zones.
- API Version Changes
: New API versions may introduce new requirements or restrictions, such as increased values for “recvWindow”.
Troubleshooting
To resolve this issue, follow these steps:
1. Monitor Network Latency
Before diving into your Node.js code, monitor your network latency using tools like ping, tcpdump, or specialized network monitoring software (e.g. Prometheus, Grafana). This will help identify potential network connectivity issues.
2. Check for time zone differences
Check that all components included in your API requirements are properly configured to handle time zone differences. Make sure that:
- Binance API is properly configured for the client location.
- Node.js and other dependencies support time zone conversions.
Updated Node.js code
To fix this issue, you can modify your node.js code as follows:
const { Client } = require('cosmia-node');
const bnb = novy zakaznik();
bnb.apiUrl = "
asynchronous function getMarketData(symbol) {
const params = {
symbol,
limit: 10, // Adjust the number of requests as needed
timestamp: Date.now() - 1000, // Adjust the timestamp offset
};
try {
const result = wait bnb.query(GET orders?symbol=${symbol}&limit=10×tamp=${params.timestamp});
return result.body;
} catch (error) {
if (error.responseCode === 2004) { // Connection error
throw new Error('A connection error occurred');
}
throw error;
}
}
// Usage example:
getMarketData('ETH/USDT')
.then((data) => console.log(data))
.catch((error) => console.error(error));
3. Adjust the “recvWindow” value.
As a last resort, you can adjust the “recvWindow” value when making requests to the Binance API. You can do this by creating a separate function that controls the timestamp of your calls. API:
“`javascript
const MAX_RECV_WINDOW = 60000; // 1 minute
const receiveTimestamps = {};
asynchronous function setReceiveTimestamp(symbol) {
const currentTimestamp = Date.now();
if (!receiveTimestamps[symbol]) {
receiveTimestamps[symbol] = [];
}
receiveTimestamps[symbol].push(currentTimestamp);
}
asynchronous function getTimestampForRequest(symbol, maxRecvWindow = MAX_RECV_WINDOW) {
setReceiveTimestamp(symbol);
// Get the latest timestamp
const timestamps = receiveTimestamps[symbol];
const lastTimestamp = Math.max(…timestamp);
if (latestTimestamp + maxRecvWindow < Date.
