Ethereum: Adding Parameters to Binance GET URL Causes Signature Error

When using the Binance API, it can be very frustrating when you add parameters to a GET request and receive a “Signature Error” message. This issue can have a number of causes, including incorrect parameter placement or a mismatch between parameter names and the corresponding API methods.

In this article, we will explore some possible solutions to fix the signature error when adding parameters to Binance’s GET URL.

Understanding Binance’s Developer FAQ

Before diving into possible solutions, it’s important to familiarize yourself with Binance’s Developer FAQ. According to the documentation, the correct placement of parameters in a GET request should look like this:

  • For API methods that don’t accept query parameters, add parameters after the API method name.
  • For API methods that accept query parameters, add parameters before or after the API method name.

However, this is not always followed by users. In some cases, they accidentally add parameters in the wrong place or use incorrect parameter names.

Possible Causes of Signature Errors

There are several possible causes of the signature error when adding parameters to Binance’s GET URL:

  • Incorrect Parameter Placement: Adding a parameter after an API method name instead of before it.
  • Parameter Mismatch: Using a parameter with a different data type (e.g. timestamp) than expected by the API method.
  • Missing or Incorrect Query String: The query string was not included in a GET request, which may be required for parameters that are not available through the API methods.

Solutions to Fix Signature Error

How to fix signature error when adding parameters to Binance GET URL:

  • Check your parameter placement: Double check your method call and make sure you add parameters after the API method name.
  • Check parameter names and data types

    : Make sure you use the correct parameter names and data types for each method call.

  • Include query string: If a parameter requires a timestamp or other time-related value, add it to the query string (e.g. ?timestamp=1643723400).
  • Test API request: Use Binance’s built-in test suite or third-party tools to test your API requests and verify that they are working properly.

To summarize, adding parameters to Binance’s GET URL can sometimes result in signature errors due to incorrect parameter placement or mismatch. By following the proper parameter placement guidelines and making sure you use the correct parameter names and data types, you should be able to resolve this issue and continue to use your API requests successfully.
