Create bot for coindeal with nodejs - Part 1

#node #coindeal #cryptocurrency #bot

Coindeal is a recognized exchange platform. It allows you to trade from several cryptocurrencies.
Like any good platform, coindeal has an API for developers that can be used to automate certain actions.

I will explain how to use the coindeal api using nodejs. In this first part, we will retrieve the information from our coindeal with a simple code.
in the second part, we will see how to automate buy and sell actions and let our bot run so that it brings us money

Requirement

Valid coindeal account
Nodejs and npm
Some free time

From your coindeal account, you will need to generate a pair of keys for using the API, you can generate it from the tab:

Account -> API

Like this:

Then, from the api page, click on the button "Create new pair of key":

You will see a window appear with your pair of keys, keep them preciously and never communicate them to anyone

Configuration

Let's start by creating the bot project.
For this, the base of nodejs:

mkdir coindeal-bot
cd coindeal-bot
npm init -y

Here is our project ready to start!
The first step will be to convert our keys to base64, this is necessary for authentication to the API.
For that, we will create a file which will only be used for the conversion of the keys

nano b64encode.js

Add this code by modifying the {publicKey} and {privateKey} values:

const str = '{publicKey}:{privateKey}';
const buff = Buffer.from(str, 'utf-8');
const base64 = buff.toString('base64');

console.log(base64);

And run the script:

node b64encode.js

You have obtained your final key which will be used from our bot to call the API

Start playing

Let's create our bot!
To begin with, we are going to retrieve some information from our account to see if the keys are working correctly.
For this, we will use the Get wallet operations endpoint of coindeal

We will need a simple and efficient library to make the API calls, I chose axios
Let's install it:

npm i axios

Create your bot file

nano myBot.js

And add your first code:
Attention, thinks to edit {yourBase64Key} in headers of axios with your keys that we encrypted in the configuration step

The base url for calling operations is this:

https://apigateway.coindeal.com/api/v1/wallets/{currency}/operations

For this example, I used the currency "btc" but you can use any currency base.
Obviously, to have a result of the call, you will have to have done some btc trade, otherwise, adjust the value by the currency you use the most

const axios = require('axios');

async function getOperations() {    
    const config = {
        method: 'get',
        url: 'https://apigateway.coindeal.com/api/v1/wallets/btc/operations',
        headers: { 
            'Authorization': 'Basic {yourBase64Key}',
            'accept': 'application/json'
        }
    }   
    let res = await axios(config)
    console.log(res.data);
}

getOperations();

Just run your bot:

node myBot.js

You will see the trading transactions you made for the selected currency appear.

This demonstrates the easiest way to make calls from the coindeal API.
Obviously, there is still a lot of endpoint to explore but we will see that in part 2
