Ethereum: Signature for this request is not valid. – Binance API

I see what’s going on here! It looks like you’re getting an error message related to the signature parameter in Binance’s API requests.

After some digging, I found that the issue is likely due to a mismatch between the expected signature format and the actual signature generated by the connector. Here’s a step-by-step explanation:

• Expected Signature Format: The expected signature format for Binance APIs typically starts with {"action":"price","id":"your-api-id","params":[{"key":"amount","value":"0.004914e-05"}],"signature":"","timestamp":"","sid":"symbol"}

• Actual Signature Generation: When you use the binance-connector library, it generates a signature in JSON format using the Binance API’s signature algorithm (HMAC-SHA256). However, this signature is not always formatted correctly.

• Error Message

  : The error message you’re seeing suggests that the connector is expecting a specific signature format, but it’s not being generated correctly.

To resolve this issue, try the following:

Step 1: Verify Signature Format

Make sure that your Binance API ID matches the expected format (your-api-id). You can check your API ID in the [Binance API documentation](

Step 2: Check Connector Configuration

Review your binance-connector library configuration file (e.g., config.json) to ensure that you’re setting up the correct API ID and signature format.

Step 3: Update Connector Code

Check if there are any updates or bug fixes in the Binance connector code. You can do this by:

a. Checking the [GitHub repository]( for any updates.

b. Using the binance-connector library’s built-in error handling mechanisms to catch and handle errors.

Step 4: Test with a Sandbox Account

Before deploying your connector to production, test it with a sandbox account to ensure that everything works as expected.

If you’re still facing issues after trying these steps, please provide more details about your connector setup, the version of the library you’re using, and any error messages you’re seeing. I’ll do my best to help you resolve the issue!

Here’s an example code snippet for reference:

import binance


api_id = "your-api-id"

api_secret = "your-api-secret"


connector_config = {

    "api_id": api_id,

    "api_secret": api_secret,

}


connector = binance.BinanceConnector(**connector_config)


price = connector.get_price("ETHUSDT", "0.00001")

print(price)

Make sure to replace your-api-id and your-api-secret with your actual Binance API credentials.

I hope this helps! Let me know if you have any further questions or concerns.
