You’ll begin by learning what Discord is and why it’s valuable.

What Is Discord?

Discord is a voice and text communication platform for gamers.

Players, streamers, and developers use Discord to discuss games, answer questions, chat while they play, and much more. It even has a game store, complete with critical reviews and a subscription service. It is nearly a one-stop shop for gaming communities.

While there are many things you can build using Discord’s APIs, this tutorial will focus on a particular learning outcome: how to make a Discord bot in Python.


What Is a Bot?

Discord is growing in popularity. As such, automated processes, such as banning inappropriate users and reacting to user requests are vital for a community to thrive and grow.

Automated programs that look and act like users and automatically respond to events and commands on Discord are called bot users. Discord bot users (or just bots) have nearly unlimited applications.

For example, let’s say you’re managing a new Discord guild and a user joins for the very first time. Excited, you may personally reach out to that user and welcome them to your community. You might also tell them about your channels or ask them to introduce themselves.

The user feels welcomed and enjoys the discussions that happen in your guild and they, in turn, invite friends.

Over time, your community grows so big that it’s no longer feasible to personally reach out to each new member, but you still want to send them something to recognize them as a new member of the guild.

With a bot, it’s possible to automatically react to the new member joining your guild. You can even customize its behavior based on context and control how it interacts with each new user.

This is great, but it’s only one small example of how a bot can be useful. There are so many opportunities for you to be creative with bots, once you know how to make them.


Note: Although Discord allows you to create bots that deal with voice communication, this article will stick to the text side of the service.


There are two key steps when you’re creating a bot:

Create the bot user on Discord and register it with a guild.Write code that uses Discord’s APIs and implements your bot’s behaviors.

In the next section, you’ll learn how to make a Discord bot in Discord’s Developer Portal.

How to Make a Discord Bot in the Developer Portal

Before you can dive into any Python code to handle events and create exciting automations, you need to first create a few Discord components:

An accountAn applicationA botA guild

You’ll learn more about each piece in the following sections.

Once you’ve created all of these components, you’ll tie them together by registering your bot with your guild.

You can get started by heading to Discord’s Developer Portal.

Creating a Discord Account

The first thing you’ll see is a landing page where you’ll need to either login, if you have an existing account, or create a new account:

*

Next, you’ll be prompted to name your application. Select a name and click Create:

*

Keep in mind that any program that interacts with Discord APIs requires a Discord application, not just bots. Bot-related APIs are only a subset of Discord’s total interface.

However, since this tutorial is about how to make a Discord bot, navigate to the Bot tab on the left-hand navigation list.

Creating a Bot

As you learned in the previous sections, a bot user is one that listens to and automatically reacts to certain events and commands on Discord.

For your code to actually be manifested on Discord, you’ll need to create a bot user. To do so, select Add Bot:

*

Notice that, by default, your bot user will inherit the name of your application. Instead, update the username to something more bot-like, such as dnth.vnTutorialBot, and Save Changes:

*

From this home page, you can view and add friends, direct messages, and guilds. From here, select the + icon on the left-hand side of the web page to Add a Server:

*

Once you’ve finished creating your guild, you’ll be able to see the users on the right-hand side and the channels on the left:

*

From this window, you’ll see the OAuth2 URL Generator.

This tool generates an authorization URL that hits Discord’s OAuth2 API and authorizes API access using your application’s credentials.

In this case, you’ll want to grant your application’s bot user access to Discord APIs using your application’s OAuth2 credentials.

To do this, scroll down and select bot from the SCOPES options and Administrator from BOT PERMISSIONS:

*

Click Authorize, and you’re done!


Note: You might get a reCAPTCHA before moving on. If so, you’ll need to prove you’re a human.


If you go back to your guild, then you’ll see that the bot has been added:

*

Looking back at the bot.py code, you’ll notice a library called dotenv. This library is handy for working with .env files. load_dotenv() loads environment variables from a .env file into your shell’s environment variables so that you can use them in your code.

Install dotenv with pip:


$ pip install -U python-dotenv
Finally, client.run() runs your Client using your bot’s token.

Now that you’ve set up both bot.py and .env, you can run your code:


$ python bot.pydnth.vnTutorialBot#9643 has connected to Discord!
Great! Your Client has connected to Discord using your bot’s token. In the next section, you’ll build on this Client by interacting with more Discord APIs.
