Ethereum: Binance API “allOrders” (HMAC SHA256) Error 1022
===========================================================
As a developer, it’s always frustrating when technical issues arise during coding endeavors. In this article, we’ll delve into the details of an error that occurred while attempting to retrieve all current orders from the Binance API using signed HMAC SHA256 requests.
The Problem: Binance API “allOrders” (HMAC SHA256) Error 1022
———————————————————
The issue arose when I attempted to send a GET request to the GET /api/v3/orderbook/all endpoint of the Binance API, expecting to receive all current orders in JSON format. However, upon execution, I encountered an error with the following code snippet:
Error ${error.status}: ${error.statusText}const hmac = new HMACSHA256('bepikey', Buffer.from('secretkey'));
const apiKey = 'YOUR_BINANCE_API_KEY';
const apiSecret = 'YOUR_BINANCE_API_SECRET';
const url =
hmac.update(Buffer.from(url));
const response = await fetch(url);
if (response.ok) {
const data = await response.json();
console.log(data);
} else {
console.error(
);
}
The error code 1022 suggests a problem with the HMAC signature verification. Let's break down what this means and how to resolve it.
What is HMAC SHA256?
---------------------
Before diving into the specifics of the issue, let's quickly review HMAC (Keyed-Hash Message Authentication Code) SHA256. HMAC is an algorithm that uses a secret key to authenticate a message by verifying its digital signature. In our case, we're using a public key (bepikey) and a secret key (secretkey), which are used as the input for the HMAC function.
HMAC SHA256 Error 1022
-------------------------
The error code 1022 indicates that the HMAC digest returned by the API is not valid. In other words, the signature of the message (in this case, the JSON data from the response) does not match the expected signature generated using the secret key.
Possible Causes:
-----------------
There are several potential causes for this error:
- Invalid or missing API credentials
: Ensure that you have used your Binance API key and secret correctly.
- Insecure network connection
: A weak or unsecured network connection may lead to issues with the HMAC signature verification process.
- Incorrect HMAC algorithm implementation: Make sure theBuffer.from(url)
is being called in a manner consistent with the expected format for creating an HMAC instance.
Resolving the Issue
-----------------
To resolve this issue, follow these steps:
- Verify your API credentials:
Ensure that you have used the correct Binance API key and secret.
- Check the network connection:
Verify that your internet connection is secure and functioning properly.
- Review HMAC algorithm implementation:
Double-check that you are callingBuffer.from(url)correctly.
Example Code (Updated)
------------------------
Here's an updated version of the code snippet that includes error handling for case 1, where the API credentials are invalid or missing:
`javascript
const hmac = new HMACSHA256('bepikey', Buffer.from('secretkey'));
const apiKey = 'YOUR_BINANCE_API_KEY';
const apiSecret = 'YOUR_BINANCE_API_SECRET';
try {
const url =
hmac.update(Buffer.from(url));
const response = await fetch(url);
if (response.ok) {
const data = await response.json();
console.log(data);
} else {
throw new Error(Error ${error.status}: ${error.statusText});
}
} catch (error) {
console.error('HMAC signature verification error:', error.
