Ethereum: Binance API “Allorders” (HMAC SHA256) Error 1022
==================================================================== ==========
As a programmer, it is always frustrating when technical problems appear during coding. In this article, we delve into the details of the error that appeared while attempting to download all current orders from the API Binance interface using signed HMAC SHA256 requests.
Problem: binance api “allorders” (hmac sha256) error 1022
—————————————————- ——–
The problem arose when I tried to send a GET request to the “Get/API/V3/V3/API/API Binance end point, expecting that I will receive all current orders in JSON format. However, after completing, I encountered a mistake with the following section of the code:
`Javascript
const hmac = new hmacsha256 ("bepikey", buffer.from ("secretkey"));
const apikey = 'your_binance_api_key';
const apisecret = 'your_binance_api_secret';
const url = = apikey} & apistecret = $ {Apisecret};
hmac.update (buffer.from (url));
Const Response = Wait for Fetch (URL);
if (response.ok) {
Const Data = Wait for response.json ();
console.log (data);
} otherwise {
console.error (error $ {error.status}: $ {error.statustext});
}
Error code 1022 suggests a problem with verification of the HMAC signature. Let’s break what it means and how to solve it.
What is HMAC SHA256?
———————-
Before immersing this problem, let’s quickly review HMAC (Keyed-Hash authentication code) SHA256. HMAC is an algorithm that uses a secret key to authenticate the message by verifying its digital signature. In our case, we use a public key (“Bepikey) and a secret key (" Secretkey "), which are used as an input for the HMAC function.
Hmac sha256 error 1022
--------------------------
Error code 1022 indicates that HMAC Digest returned by API is incorrect. In other words, the signature of the message (in this case JSON data from the answer) does not match the expected signature generated by a secret key.
Possible reasons:
------------------
There are several potential causes of this error:
* An incorrect or missing API certificates : Make sure you have used your API Binance key correctly.
* Uncertain network connection : A weak or unsecured network connection can lead to problems with the HMAC signature verification process.
* Incorrect implementation of the HMAC algorithm
: Make sure that "buffer.from (URL) is caused in a manner consistent with the expected format of creating HMAC instance.
Solving the problem
------------------
To solve this problem, follow the following steps:
- Check your API certificates:
Make sure you have used the correct API key and the mystery of Binance.
- Check the network connection:
Check if your internet connection is safe and works properly.
- Review the implementation of the HMAC algorithm:
Check twice that you call "buffer.from (url)" correctly.
Sample code (updated)
-------------------------
Here is an updated version of a fragment of the code, which includes error handling in the case of 1, in which API certificates are incorrect or missing:
Javascript
const hmac = new hmacsha256 ("bepikey", buffer.from ("secretkey"));
const apikey = 'your_binance_api_key';
const apisecret = 'your_binance_api_secret';
to try {
const url = = apikey} & apistecret = $ {Apisecret};
hmac.update (buffer.from (url));
Const Response = Wait for Fetch (URL);
if (response.ok) {
Const Data = Wait for response.json ();
console.log (data);
} otherwise {
Throw a new mistake (Error $ {error.status}: {error.statustext}`);
}
} catch (error) {
Console.error (“HMAC signature verification error:”, error.
