I can help with this. An experienced error message suggests that the signature of HMAC SHA 256 does not generate properly. Here is a detailed guide to solve the problem:

Step 1: Check the secret button

Before you send the signature of HMBM Sha 256, make sure the secret key (config.ecret_key) is accurate and does not threaten.

Python

To bring in bite

Replace the API button and the secret button

Api_key = “Your_api_key”

secree_key = “your_secret_key”

Api_config = {

“Api_key”: Api_key,

“Secret_key”: secret_key

Iche

Generate signature Hmac Sha 256

Signature = binance.api_sign_x_sign (Config.api_key, Config.Secret_key)

`

Step 2: Use the correct endpoint of Binance API

Be sure to use the right endpoint to send a craft to the API binans. The endpoint is https: // api.binance.com/api/v3/mytrades'.

Python

Determine the endpoint of your API

Endpoint = “

`

Step 3: Update HMAC signature generation

To create the HMMB SHA 256 signature, you must use the “binance.api_sign_xign” function and provide appropriate parameters.

`Python

Determine the parameters to produce the signature hmac -to produce

Api_config = {

“Api_key”: Api_key,

“Secret_key”: Secret_key

Iche

Generate signature Hmac Sha 256

try:

Signature = binance.api_sign_x_sign (endpoint, api_config)

Along with the exception like E:

Drive the exceptions during the signature generation

Print (F “Error Error Hmac Sha 256 Signature: {E}”)

`

More recommendations

• Make sure the secret key is not encoded in the code. Consider using environmental variables or securely solving secret management.

• If you use the Python’s Built -in artisan signature “Hashlib”, make sure you use the appropriate parameters and algorithms for HMAC SHA 256.

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

Here is the updated version of the code that contains these recommendations:

`Python

To bring in bite

Import the Hashlib

Replace the API button and the secret button

Api_key = “Your_api_key”

secree_key = “your_secret_key”

Determine the binance API endpoint

Endpoint = “

Def Genereate_hmac_signature (Api_config):

Production of Hmac Sha 256 Signature by using Hashliba Library

signature = hashlib.sha256 ()

Signature.update (p.encode (api_config [“api_key”])))

Signature.update (p.encode (secread_key))

Return signature.hex ()

Determine the parameters to produce the signature hmac -to produce

Api_config = {

“Api_key”: Api_key,

“Secret_key”: secret_key

Iche

Generate signature Hmac Sha 256

Signature = Generate_hmac_signatura (Api_config)

`

Following these steps and recommendations, you should be able to solve the signatures of HMMB SHA 256 for API Binans.
