I am trying to connect to Binance api from my Rails application. But every time I am getting 401 unauthorized error message from Binance. Below is my code.

  class Binance
    END_POINT = 'https://api.binance.com'.freeze
    KEY = 'my-binance-key'
    SECRET = 'my-binance-secret'

    def self.account_info
       url = "#{END_POINT}/api/v3/account"
       query_string = "timestamp=#{DateTime.now.strftime('%Q')}"
       digest = OpenSSL::Digest.new('sha256')
       signature = OpenSSL::HMAC.hexdigest(digest, SECRET, query_string)
       url = "#{END_POINT}/api/v3/account?#{query_string}&signature=#{signature}"
       response = RestClient.get(url, headers: { 'X-MBX-APIKEY': KEY })
    end
  end

Here is a link from Binance api with example:

Getting a 401 from what, your app or the external API? – tadman Dec 18 '20 at 02:45
@tadman from external API (Binance) – r3b00t Dec 18 '20 at 02:50
@r33b00t the sample in github curl is a POST request, you use get – darkash Dec 18 '20 at 05:45
@darkash ya in example they are using `order` endpoint which required post. But for `account_info` it requires get. – r3b00t Dec 18 '20 at 06:13
any solution here? – Fdwillis May 27 '23 at 18:20
Hope this is not too late, but https://github.com/binance/binance-connector-ruby has the code of signature, which maybe helpful. – Binance Aug 25 '23 at 00:40
