Ethereum: how to send HMAC SHA 256 Secret key to binance api?

February 8, 2025 By CRYPTOCURRENCY No Comments

I can help you with it. The error message you appointed indicates that the HMAC Sha 256 signature is not properly created. Here is a step -by -step guide to help solve the problem:

Step 1: To secure the secret key

Before sending the HMAC Sha 256 signature, make sure your secret key (config.secret_key) is correct and is not compromised.

`Python

import bin

Replace the application subscription key and secret key

API_KEY = "Your_API_KEY"

Secret_key = "your_secret_Key"

API_CONFIG = {

"API_KEY": API_KEY,

"Secret_key": Secret_key

}

Create the HMAC Sha 256 signature

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

Step 2: Use the correct Binance API end point

Make sure you use the right end point to send stores to the Binance application subscription. The end point is https: // api.binance.com/api/v3/mytrades'.

Python

Set the API terminal point

endpoint = "

Step 3: Refresh HMAC Signature Generation

In order to create the HMAC Sha 256 signature, you must use the binance.api_sign_X_Sign function and provide the right parameters.

`Python

Set the HMAC signature formation parameters

API_CONFIG = {

"API_KEY": API_KEY,

"Secret_key": Secret_key

}

Create the HMAC Sha 256 signature

Try:

Signature = Binance.api_Sign_X_Sign (endpoint, API_CONFIG)

Waiting for the exception to e:

Deal with all the exceptions that take place to create the duration of the duration

Print (F "Creating Errors HMAC Sha 256 Signature: {E}")

Other Recommendations

  • Make sure your secret key is not encoded in your code. Consider the use of environmental variables or safe secrets management solution.

  • If you use Python Build -in HashLib library to sign shops, make sure you are using the right parameters and algorithms of the HMAC Sha 256.

  • When creating signatures, always use the same secret key for all API functions.

Here’s an updated version of the code containing the recommendations of the thesis:

`Python

import bin

Bring the hashlib

Replace the application subscription key and secret key

API_KEY = "Your_API_KEY"

Secret_key = "your_secret_Key"

Set the Binance API terminal

endpoint = "

Def Generate_hmac_Signature (API_CONFIG):

Create the HMAC Sha 256 signature with HashLib Library

Signature = hashlib.sha256 ()

Signature.update (str.encode (API_CONFIG ["API_KEY"]))))

Signature.update (str.encode (Secret_key))

Return signature.hx ()

Set the HMAC signature formation parameters

API_CONFIG = {

"API_KEY": API_KEY,

"Secret_key": Secret_key

}

Create the HMAC Sha 256 signature

Signature = Generate_hmac_Signature (API_CONFIG)

By following the thesis and recommendations, you should be able to solve all the problems of creating HMAC SHA, 256 signatures for your Binance application subscription.
