I can help you with that. The error message you’re encountering suggests that the HMAC SHA 256 signature is not being generated correctly. Here’s a step-by-step guide to help you resolve the issue:

Step 1: Verify the Secret Key

Before sending the HMAC SHA 256 signature, make sure that your secret key ( config.Secret_Key ) is correct and has not been compromised.

import binance







Replace with your API key and secret key

api_key = "YOUR_API_KEY"

secret_key = "YOUR_SECRET_KEY"


api_config = {

    "API_KEY": api_key,

    "SECRET_KEY": secret_key

}



Generate the HMAC SHA 256 signature

signature = binance.api_sign_x_sign(config.API_Key, config.Secret_Key)

Step 2: Use the Correct Binance API Endpoint

Make sure that you’re using the correct endpoint for sending trades to your Binance API. The endpoint is

Define the API endpoint

endpoint = "

To generate an HMAC SHA 256 signature, you need to use the binance.api_sign_x_signfunction and provide the correct parameters.

Define the parameters for the HMAC signature generation

api_config = {

    "API_KEY": api_key,

    "SECRET_KEY": secret_key

}



Generate the HMAC SHA 256 signature

try:

    signature = binance.api_sign_x_sign(endpoint, api_config)

except Exception as e:

    
Handle any exceptions that occur during signature generation

    print(f"Error generating HMAC SHA 256 signature: {e}")

• If you're using Python's built-in hashlib` library to sign the trades, ensure that you’re using the correct parameters and algorithms for HMAC SHA 256.

• When generating signatures, always use the same secret key for all API operations.

Here’s an updated version of your code incorporating these recommendations:

import binance

import hashlib



Replace with your API key and secret key

api_key = "YOUR_API_KEY"

secret_key = "YOUR_SECRET_KEY"



Define the Binance API endpoint

endpoint = "


def generate_hmac_signature(api_config):

    
Generate the HMAC SHA 256 signature using hashlib library

    signature = hashlib.sha256()

    signature.update(str.encode(api_config["API_KEY"]))

    signature.update(str.encode(secret_key))

    return signature.hex()



Define the parameters for the HMAC signature generation

api_config = {

    "API_KEY": api_key,

    "SECRET_KEY": secret_key

}



Generate the HMAC SHA 256 signature

signature = generate_hmac_signature(api_config)

By following these steps and recommendations, you should be able to resolve any issues with generating HMAC SHA 256 signatures for your Binance API.
