Ethereum: Binance {code: -1022, msg: ‘Signature for this request is not valid.’}

I can provide you with an article that explains the problem and how to solve it. However, please note that I assume basic knowledge of Next.js, SSR (Server Rendering), and the Binance API.

Binance Ethereum API signature issue in Next.js with Simple JavaScript Fetch

As a developer building a blockchain-based application using Next.js, you’ve probably encountered problems integrating the Binance API. One common problem is receiving an error message indicating that your request signature is invalid. In this article, we will consider the causes of this problem and suggest steps to solve it.

Problem

When making API requests to Binance using JavaScript Fetch or a similar library, you must include your API key in the URL request string. However, the Binance API expects the signature (also known as HMAC-SHA-256) to be included in the request body, not the request string.

The code snippet presented in the article shows how the API key is passed in the request line:

var keysBuy = {

  "APIkey": 'my API key',

  // ...

}

When you try to execute an API request using JavaScript Fetch with this data, you will receive an error message:

{

  "code": -1022,

  "msg": "The signature for this request is invalid."

}

Solution

To resolve this issue, you need to update your API key data to include a signature instead of a request string. The correct way to transfer the signature is to use the Authorization' header in the body of the request.

import { ethers } from 'ethers';


// Replace the API key and other credentials with your own

const apikey = 'my api key';

const secretKey = 'your secret key';

const contractAddress = '0x...'; // your Binance contract address


async function getOrders() {

  const account = await ethers.getSigner();

  constant order = waiting for an invoice. order({

    symbol: "BTCUSDT",

    side: "buy",

    type: "limit",

    quantity: 1,

    arrow time: '3d'

  });


  // Include the signature in the body of the request

  const signature = await ethers.ethers.signMessageDigest(

    order.rawData.rawTxHash,

    account.privateKey,

    { encoding: 'base64' }

  );


  return {

    signature

    contract address,

    apices

  };

}


export getOrders by default;

In this example, we use the signMessageDigestfunction to generate a signature for an order request. We includesignature,contractAddressandapikey` in the request body.

Next Steps

Now that you’ve resolved the signature issue, make sure you’re making API requests in the correct format. You should also consider implementing error handling and logging mechanisms to better handle any errors that may occur during the development of your application.

In addition, if you have additional problems or questions, do not hesitate to ask for help. I hope this article helps you solve the signature problem in your Next.js applications using the Binance API!
