I can help you with that. The error message you encounter suggests that the signature of the HMAC SHA 256 is not created correctly. Here is a detailed guide to help you solve the problem:

Step 1: Verify the secret key

Before sending a signature of HMAC SHA 256, make sure your secret key (config.secret_key) is correct and not at risk.

`Python

import binance

Replace with your API key and the secret key

Api_key = “your_api_KEY”

Secret_Key = “Your_secret_key”

API_CONFIG = {

“Api_Key”: Api_Key,

“Secret_Key”: Secret_key

}

Generate signature HMAC SHA 256

Signature = binance.api_sign_x_sign (config.apip_key, config.secret_key)

`

Step 2: Use the correct ending point of the API Binance API

Make sure you are using the right endpoint to send stores to your Binance API. The end point is https: // api.binance.com/API/V3/Mytrada.

`Python

Define the API endpoint

Endpoint = “

`

Step 3: Update the HMAC signature generation

To generate the signature of HMAC SHA 256, you must use the binance.api_sign_x_sign and provide the correct parameters.

`Python

Define parameters for generating signature HMAC

API_CONFIG = {

“Api_Key”: Api_Key,

“Secret_Key”: Secret_key

}

Generate signature HMAC SHA 256

try:

Signature = binance.api_sign_x_sign (endpoint, API_CONFIG)

In addition to the exception as E:

Manage all the exceptions that occur during signature generation

Print (f “error generating HMAC SHA 256 Signature: {e}”)

`

More recommendations

• Make sure your secret key is not hard in your code. Consider the use of environmental variables or safely solutions for secrets.

• If you use the built -in library hashlib Python to sign stores, make sure you use the correct parameters and algorithms for HMAC SHA 256.

• Always use the same secret key for all API operations when generating signatures.

Here is an updated version of your code that contains the following recommendations:

`Python

import binance

Import hashlib

Replace with your API key and the secret key

Api_key = “your_api_KEY”

Secret_Key = “Your_secret_key”

Define the Binance API endpoint

Endpoint = “

Def generte_hmac_signature (API_CONFIG):

Generate signature HMAC SHA 256 using the hashlib library

Signature = hashlib.sha256 ()

Signature.update (p.encode (API_CONFIG [“API_KY”))))))))

Signature.Update (p.encode (Secret_key))

Return Signature.Hex ()

Define parameters for generating signature HMAC

API_CONFIG = {

“Api_Key”: Api_Key,

“Secret_Key”: Secret_key

}

Generate signature HMAC SHA 256

Signature = generate_hmac_signature (API_CONFIG)

`

According to these steps and recommendations, you should be able to solve any problems with generating the signatures of HMAC SHA 256 for your Binance API interface.
