PSA: A pretty clever phishing email

I got a message warning me that my Twitter account was about to be suspended for suspicious activity, inviting me to click a button to prevent this. The URL the button went to *was* an x.com link, but it used a security vulnerability in Twitter's backend that allowed redirections to push me to an OATH server that would prompt me for my Twitter login and 2FA, and then send the attacker a valid token they could use to take over my account.

Here's the (redacted) attack link:

https://x.com/ [BREAK INSERTED] i/oauth2/authorize?response_type=code&client_id= [UNIQUE ID REMOVED] Q&redirect_uri=https%3A%2F%2Ftwo.opensourced.us%2Fapi%2Fcallback%3Fi%3Dtwit&scope=tweet.read+users.read+mute.write+tweet.write+tweet.moderate.write+offline.access&code_challenge= [UNIQUE ID REMOVED] &code_challenge_method=plain

I am happy to announce that MochiDex is now officially public and you can now invite it to your servers. The bot allows you to catch, collect, and trade mochis.

Each mochi has its own card that includes art, their stats and their ability. Currently around half the mochi's have original art in their card, but eventually every mochi will have art! The art has been made by many different artists in the fandom and I hope you enjoy their work .

Right now we have added 64 mochis, but we don't plan on stopping until every Hetalia character is in the bot . Only 29 of these mochis were designed by Himaruya, so we have had to design mochis for most of the cast.

MochiDex Setup:

Click this link that allows you to invite the bot: https://discord.com/oauth2/authorize?client_id=1151205638521770035&scope=bot+applications.commands&permissions=537193536

Once the bot joins the server an admin needs to do the "/config channel" command to choose in which channel they would like the mochis to spawn

After doing that you just have to wait! The mochis can take around 45 to 55 minutes to spawn, they can spawn even earlier, it all depends on server activity!

4. Whichever mochi spawns depends on it's rarity, each mochi has a rarity which decides its chance to spawn. Some mochis like America are very rare, and others like Latvia are very common. Keep that in mind when trading

Oh and by the way, currently until November 3, the bot is having a Halloween event during which you can get rare "spooky" variants that change the card's theme.

We also have a discord server where you can find the rarity list, see updates and make questions/suggestions! Feel free to join!

How to archive a Discord channel

I'm going to say this way ahead of time: this is going to be waaaaaaay more of an annoying process than it should be. Discord should allow exporting the channel history to server owners, without the need of doing all this. I won't blame you if you give up.

Get the DiscordChatExporter application to download the chat history

This program has two versions

one that has a graphical interface, but works on Windows only

one that has a command line interface, but works on Windows, Linux and macOS

This guide covers the first. The second one maybe next time, in another post. The second version also makes it easier to download every channel on the server.

Step 1: Go to here, and download the latest version in the zip file named DiscordChatExporter.zip

Step 2: Unpack the zip file

Step 3: Run DiscordChatExporter.exe

Step 4: Dismiss the scary looking warning as this will show up for any program that which developer can't afford paying $629 a year.

Step 5: Close the welcoming message and you'll see the application interface:

Prepare an access token. Do not share it to anyone else - treat it the same way as you treat your password.

There are two ways to do it:

Approach 1: use your own access token, will work with any channel you're able to access, including Direct Messages, but it is a violation of Discord Terms of Service, and therefore your Discord account could get banned for it. Use at your own risk.

Follow the instructions here, which are fairly detailed step-by-step instructions for Chrome, Firefox, and also the desktop app. I'm gonna expand more on approach 2 as I had to figure it out myself, and the current instructions for approach 2 are not really adequate enough. If you go with approach 1, skip down the entire section below, until the "Paste the token in the Token textbox and click the arrow button" section.

Approach 2: create a bot account, invite it to your server, and use its access token. This process assumes you have enough privileges to invite bots to the server ("Manage Server" permission), and therefore, but is also 100% okay as far as Discord's Terms of Service are concerned. It is also generally safer, as accidental leaking of the token will not risk you losing your user account.

Step 1: Go to the Discord developer portal.

Step 2: Create a new application by clicking the "New Application" button

Step 3: Name it however you want, I personally named it "mlemgrab". Agree to the scary sounding long ass terms of service.

Step 4: Go to the Bot section, scroll down to the "Privileged Gateway Intents"

Step 5: Enable the "Message Content Intent". We don't have to worry about the "if your bot is in more than 100 servers" part because our bot will never be in this many servers.

Step 6: Save changes by pressing the green button "Save Changes"

Step 7: Go to "OAuth2" followed by "URL Generator"

Step 8: Select the "bot" scope and then "Read Messages/View Channels" and "Read Message History" permissions

Step 9: Copy the link at the bottom and visit it:

Step 10: Press "Continue", and approve the required permissions by clicking Authorize. Once you do it, the bot account is on the server.

Step 11: Go to "Bot" and click the "Reset Token" button to get the token that will allow you to act (in our case, getting all the messages) using the bot user. If you lose that token, you can click reset again to get a new one.

Paste the token in the Token textbox and click the arrow button

Select the server, and then the channel you want to archive

Click the download button on the bottom right

Select where you want to save it, and the format. HTML is good for easy browsing and preview in a web browser, JSON is good for further processing (let's say someone else later writes a program for importing the conversation elsewhere).

For archivization purposes I recommend saving in both HTML and JSON.

Click "More" for more options.

By default the program will not download any message attachments nor avatars or emotes. If you want that, select "Download assets" option. Preferably while also selecting the "Reuse assets" option and selecting a single directory for assets if you want to archive multiple channels.

You can also select the specific time range and using the partition limit - split the archive into several files each containing N messages.

Press Export. Wait. The progress bar will move very slowly.

Once it is done, you should be able to open the HTML file with your web browser.

Treat anything on Discord as media that will be lost

Do not use Discord to host your files. Do not rely on Discord to preserve your text. DO NOT RELY ON DISCORD FOR ANY KIND OF PRESERVATION OR HOSTING!!

It CAN be lost, it WILL be lost! You must consider Discord as a part of the Core Internet, controlled by one company that hosts the servers.

I thought it was impressive at first that it replaced IRC, but now I am horrified. If the company behind Discord went under today, how many friends would you lose?

How many relationships? How much writing?

You may think this won't happen, but I remember when AIM went down and along with it, entire novels worth of interaction with my oldest friend.

IT CAN HAPPEN TO YOU. IT WILL HAPPEN AGAIN. NO COMPANY IS INFALLIBLE.

Back up your files! Download anything you've saved to Discord NOW, before the API changes go into effect! And DO NOT RELY ON THEM FOR HOLDING IMPORTANT FILES!

How to Secure Your Java Applications: Authentication, Encryption, and Best Practices

Introduction

Security is a critical concern in Java applications.

Overview of key security aspects: authentication, encryption, and best practices.

Importance of preventing unauthorized access, data breaches, and vulnerabilities.

1. Authentication in Java Applications

1.1 Role of Authentication

Ensures that only authorized users can access the application.

Prevents identity theft and unauthorized access.

1.2 Implementing Authentication in Java

1.2.1 Basic Authentication with Spring Security

java@Configuration @EnableWebSecurity public class SecurityConfig { @Bean public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { http.authorizeHttpRequests(auth -> auth .anyRequest().authenticated()) .httpBasic(Customizer.withDefaults()); return http.build(); } }

✅ Use Case: Protects REST APIs using Basic Authentication.

1.2.2 OAuth 2.0 with Spring Security

Secure APIs with OAuth 2.0 and JWT (JSON Web Tokens).

Integrate with Google, Facebook, or custom authorization servers.

Example: Configuring OAuth2 Loginjava@Configuration @EnableWebSecurity public class SecurityConfig { @Bean public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { http.oauth2Login(); return http.build(); } }

✅ Use Case: Implementing SSO (Single Sign-On).

2. Encrypting Data in Java

2.1 Why Encryption is Important

Protects sensitive information such as passwords, tokens, and user data.

Prevents data leakage in case of breaches.

2.2 Hashing Passwords with BCrypt

Avoid storing plain-text passwords.

Use BCrypt for secure hashing.

Example: Hashing a password using BCryptjavaimport org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;public class PasswordHashing { public static void main(String[] args) { BCryptPasswordEncoder encoder = new BCryptPasswordEncoder(); String hashedPassword = encoder.encode("securePassword123"); System.out.println("Hashed Password: " + hashedPassword); } }

✅ Use Case: Safely storing user passwords in databases.

2.3 AES Encryption for Data Protection

AES (Advanced Encryption Standard) is used for encrypting sensitive data.

Example: AES Encryption in Javajavaimport javax.crypto.Cipher; import javax.crypto.KeyGenerator; import javax.crypto.SecretKey; import java.util.Base64;public class AESEncryption { public static void main(String[] args) throws Exception { KeyGenerator keyGen = KeyGenerator.getInstance("AES"); keyGen.init(256); SecretKey secretKey = keyGen.generateKey(); Cipher cipher = Cipher.getInstance("AES"); cipher.init(Cipher.ENCRYPT_MODE, secretKey); byte[] encryptedData = cipher.doFinal("Sensitive Data".getBytes()); System.out.println("Encrypted: " + Base64.getEncoder().encodeToString(encryptedData)); } }

✅ Use Case: Encrypting credit card information in e-commerce applications.

3. Best Security Practices for Java Applications

3.1 Secure API Endpoints

Use HTTPS (SSL/TLS) to encrypt data transmission.

Validate and sanitize user inputs to prevent SQL Injection and XSS.

3.2 Secure Dependency Management

Regularly update dependencies to patch vulnerabilities.

Use OWASP Dependency-Check to identify security risks.

3.3 Implementing Role-Based Access Control (RBAC)

Restrict access permissions based on user roles.

java@Configuration @EnableWebSecurity public class SecurityConfig { @Bean public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception { http.authorizeHttpRequests(auth -> auth .requestMatchers("/admin/**").hasRole("ADMIN") .anyRequest().authenticated()) .formLogin(Customizer.withDefaults()); return http.build(); } }

✅ Use Case: Restricting admin dashboard access.

3.4 Preventing CSRF (Cross-Site Request Forgery)

Use Spring Security CSRF protection (enabled by default).

Token-based authentication (JWT) can help mitigate CSRF risks.

3.5 Logging and Monitoring

Implement audit logging to track security events.

Use tools like ELK Stack (Elasticsearch, Logstash, Kibana) for monitoring.

Conclusion

Java applications need robust authentication, encryption, and security best practices.

Use Spring Security for authentication, AES for encryption, and RBAC for access control.

Stay updated with security patches and vulnerability scans.

Essential Components of a Production Microservice Application

DevOps Automation Tools and modern practices have revolutionized how applications are designed, developed, and deployed. Microservice architecture is a preferred approach for enterprises, IT sectors, and manufacturing industries aiming to create scalable, maintainable, and resilient applications. This blog will explore the essential components of a production microservice application, ensuring it meets enterprise-grade standards.

1. API Gateway

An API Gateway acts as a single entry point for client requests. It handles routing, composition, and protocol translation, ensuring seamless communication between clients and microservices. Key features include:

Authentication and Authorization: Protect sensitive data by implementing OAuth2, OpenID Connect, or other security protocols.

Rate Limiting: Prevent overloading by throttling excessive requests.

Caching: Reduce response time by storing frequently accessed data.

Monitoring: Provide insights into traffic patterns and potential issues.

API Gateways like Kong, AWS API Gateway, or NGINX are widely used.

Mobile App Development Agency professionals often integrate API Gateways when developing scalable mobile solutions.

Oracle Apex Oauth2 Example

OAuth2 in Oracle APEX: A Practical Guide and Example

OAuth2 is a contemporary and secure authorization framework that allows third-party applications to access protected resources on behalf of a user. By implementing OAuth2 in Oracle APEX, you can provide controlled access to your APEX application’s data and functionality, enabling seamless integration with other services.

Why use OAuth2 with APEX?

Enhanced Security: OAuth2 offers a robust security layer compared to traditional username and password-based authentication. It uses tokens rather than directly passing user credentials.

Fine-grained Access Control: OAuth2 allows you to define specific scopes (permissions) determining the access level granted to third-party applications.

Improved User Experience: Users can conveniently authorize applications without repeatedly sharing their primary credentials.

Prerequisites

A basic understanding of Oracle APEX development

An Oracle REST Data Source (ORDS) instance, if you want to integrate with ORDS-defined REST APIs

Steps for Implementing OAuth2 in Oracle APEX

Create an OAuth2 Client:

Within your APEX workspace, navigate to Shared Components -> Web Credentials.

Click Create and select the OAuth2 Client type.

Provide a name, ID, client secret, and any necessary authorization scopes.

Obtain an Access Token:

The method for obtaining an access token will depend on the OAuth2 flow you choose (e.g., Client Credentials flow, Authorization Code flow).

Utilize the Access Token:

Include the access token in the Authorization header of your API requests to protected resources. Use the format: Bearer .

Example: Accessing an ORDS-based REST API

Let’s assume you have an ORDS-based REST API endpoint for fetching employee data that requires OAuth2 authentication. Here’s how you would configure APEX to interact with it:

Create a REST Data Source:

Go to Shared Components -> REST Data Sources.

Set the authentication type to OAuth2 Client Credentials Flow.

Enter your OAuth2 token endpoint URL, client ID, and client secret.

Use the REST Data Source in Your APEX Application:

Create APEX pages or components that utilize the REST Data Source to fetch and display employee data. APEX will automatically handle obtaining and using the access token.

Additional Considerations

Access Token Expiration: OAuth2 access tokens usually have expiration times. Implement logic to refresh access tokens before they expire.

OAuth2 Flows: Choose the most suitable OAuth2 flow for your integration use case. The Client Credentials flow is often used for server-to-server integrations, while the Authorization Code flow is more common for web applications where a user is directly involved.

Petit recapitulatif du flow OAuth2

OAuth2 permet a des 3ce partie d'acceder a des données utilisateurs sans reveler leur mot de passe via l'échange de tokens.

client: celui qui désire acceder à une resource

resource owner: l'utilisateur qui possède une resource

auth server: serveur qui authentifie les utilisateur et emet des jetons

resource server: héberge une resource protégée

Oauth2 flows

Authorization code:

le client désire acceder à une resource a nom de l'utilisateur

l'utilisateur est dirigé vers l' auth server pour login et donner les accès au client

ensuite l'auth server envoie un code d'authorisation au client

le client envoie le code d'authorisation à l'auth server en échange d'un token courte durée

le client contacte le resource server avec le token qui lui donne accès

Client credential:

le client désire accéder à des resources qui lui appartiennent

le client s'authentifie au serveur via ses credentials (clientId + clientSecret)

l'auth server envoie un access token au client

le client peut utiliser ce token pour accéder les données

Hey there! If you're a developer building web applications with ASP.NET Core, you know that authentication and authorization can be a complex and challenging aspect of the development process. Luckily, there's a solution that can simplify this process: Identity Server.

Identity Server is an open-source framework that provides a secure and flexible solution for implementing authentication and authorization in your ASP.NET Core applications. It allows you to implement single sign-on (SSO) and access control in a centralized manner, reducing the amount of code you need to write and maintain.

One of the biggest advantages of using Identity Server is that it supports a wide range of authentication protocols, including OpenID Connect, OAuth2, and SAML2. This means that you can easily integrate with external identity providers like Facebook, Google, and Microsoft, giving your users a seamless and secure experience.

Identity Server also provides a variety of features that make it easy to customize the authentication process to fit your specific needs. For example, you can create your own implementation of the interfaces provided by the framework to add custom authentication schemes, or customize the UI of the login pages to match the look and feel of your application.

Another advantage of using Identity Server is that it provides comprehensive documentation and a supportive community of developers who can help you if you run into any issues.

In conclusion, Identity Server is an excellent solution for simplifying authentication and authorization in your ASP.NET Core applications. If you're working on a project that requires user authentication, be sure to check out Identity Server and see how it can streamline your development process!

YouTube Short | What is Difference Between OAuth2 and SAML | Quick Guide to SAML Vs OAuth2

Hi, a short #video on #oauth2 Vs #SAML #authentication & #authorization is published on #codeonedigest #youtube channel. Learn OAuth2 and SAML in 1 minute. #saml #oauth #oauth2 #samlvsoauth2 #samlvsoauth

What is SAML? SAML is an acronym used to describe the Security Assertion Markup Language (SAML). Its primary role in online security is that it enables you to access multiple web applications using single sign-on (SSO). What is OAuth2?  OAuth2 is an open-standard authorization protocol or framework that provides applications the ability for “secure designated access.” OAuth2 doesn’t share…

HOW TO MAKE A SIMPLE DISCORD BOT THAT RESPONDS TO MESSAGES!!!

(updated tutorial! trust me, it's super easy!!)

Pretty much every Discord bot tutorial I’ve seen is either outdated, way too complicated, or a video... so I’ve decided to take matters into my own hands and make my own tutorial!!!

So here’s how to make a response bot with Python and Repl.it, step by step, with pictures. NO CODING EXPERIENCE NEEDED

Step 1: HAVE A DISCORD ACCOUNT AND A SERVER!

Seeing as you’re here, I’ll assume you know what discord is and have an account. I won’t explain this bit to you (:

Step 2: MAKE A REPL.IT ACCOUNT 

Repl.it is where your bot’s code is gonna live, so you need to make an account for it!!

https://repl.it/signup?goto=%2F~

Step 3: STARTING THE BOT!

Now you’re gonna go to https://discord.com/developers/applications and make an application!

Once you’re there, click that blue “New Application” button and make a new application!

Once you've done that, you should be here

Now go to the bot section and click add bot

Congrats! You've got the beginnings of a robot! Do not close this tab, we'll need it later!

Step 4: ADDING THE BOT!

Now, you need to add the bot to a server so you can use it! 

Go to the “General Information” page of your bot/ app, and copy the application ID by clicking the handy little copy button

now, replace where this link says [YOUR CLIENT ID HERE] with your client ID and go to said link:

https://discordapp.com/api/oauth2/authorize?scope=bot&client_id=[YOUR CLIENT ID HERE]

(example: https://discord.com/oauth2/authorize?scope=bot&client_id=714083849235333161)

Authorise it and bam! It's in your server!

Step 5: ACTUALLY CODING THE BOT!!

FINALLY! 

This bit is REALLY easy, because I’ve made you some base code, so you don’t have to do much!!

Go to: https://repl.it/@stealingpotatos/tutorialbotbase1

Now click the "Fork" button and you've got your own copy of the code!!! Well done!!

Here comes the actual coding! Replace "trigger word" with whatever you want to trigger the bot, and "response" with the-- well I'm sure you can work it out!

THE TRIGGER NEEDS TO BE IN ALL LOWER CASE

But your bot won't work just yet!

step 6: JOINING YOUR BOT AND CODE

Back in the Discord Dev Portal, go to the Bot tab and click "RESET TOKEN" and then copy it!

Back on repl.it, click the lock icon to enter the Secrets tab

Once you're there, add a new secret called "SUPER_SECRET_BOT_TOKEN" and make the value your copied bot token!

AND THATS IT!!! You have a working bot!!

I'm so proud of you!!!! :D

Have fun botting!!

extras: KEEPING YOUR BOT ONLINE

Because of the “keep_alive” function, your bot will continue to be online for about an hour after you close the tab.

But if you want it online all the time, here's a tutorial I made a while back on keeping your bot online 24/7!

extras: ADDING MORE RESPONSES

Super simple!! 

If you want multiple triggers for the same response, copy & paste the “(””) in message.content.lower()” part of the statement, + add an or

Like that!

And for adding another trigger/response entirely, just copy & paste the statement entirely, and change the “if” to an “elif” if you don’t want both things to trigger at once.

Like this!!

If you don’t already know python, I’d very much recommend learning it if you’re going to be doing more bot coding!!

Thank you for reading, and if you have ANY QUESTIONS AT ALL, my askbox is open (and has anon if you think the question is kinda dumb and don’t want your name on it. It’s not a dumb question, ask me!)

Also if you have any questions about adding new functions, I’ll try to help you too! This blog is gonna be all abt that!!

How To Set Up Your Own Discord Bot: A Guide [v13 update]

Step 1: Go to https://discord.com/developers/applications

Make sure you are signed in to discord. On the top right hand corner, you will see a button that says New Application. Get to clicking!

Step 2: You will be asked for a name. This could be any name, but preferably the one you want your bot to have. Make sure it has a cool name, like Potato Queen, or Jack the Ripped Bot.

Once you have done that, click Create.

Step 3: You will come to a page that shows all the General Information. But you have not created your bot yet! This is just the application page. You can put in your App Icon, Description and the likes, before clicking on Bot at the side bar.

Step 4: You should reach a page with a button that says Add Bot. Well, what are you waiting for? Go ahead and click it!

A whole new page will pop up, with information about your new bot. Remember, you can’t destroy a bot, so make sure you’re definitely wanting a bot when you’re doing this.

From here, you can see your bot’s username as well as its profile picture. You can change it if you want.

IMPORTANT: There is also something called Token. YOU SHOULD NEVER SHOW THIS TO ANYONE ELSE. It is the one thing that will bring your bot to life (it basically controls your bot) and if it’s out in the open, it is best to regenerate a new one.

When you scroll down, you will see Authorization Flow. This is where you can choose to make your bot public or private. Making it public means that others can add it to their own servers, without your help. If it’s private, only YOU can add this bot to servers.

Step 5: Invite your bot into your server.

The link to do this should be: https://discord.com/oauth2/authorize?client_id=[clientidhere]&scope=bot&permissions=[permissionnumber]

An example is: https://discord.com/oauth2/authorize?client_id=707835242475421767&scope=bot&permissions=8 [this has admin permissions]

or you can just use: https://discord.com/oauth2/authorize?client_id=707835242475421767&scope=bot

And you’re done! At least with the application part.

NOW WE MOVE ON TO THE CODING PART. [Note: This is in JS because I love JS. Someday I might do a guide for Python too but we will see.]

The basic things you need: 1. Visual Studio Code 2. Node JS

You can see how to download either one from HERE.

Then, you will need to download discord.js.

Create a folder for your discord bot things, and then open up Visual Studio Code.

Create a new file called index.js and this will be your main page, where you get your bot running. The basic codes inside it would be:

TOKEN: Remember that token that I said you can’t tell anyone? Yeah, put it in there like client.login(”IWEUTWEITU”) where that keysmash is your token.

From here, if you’re using Visual Studio Code, just go to your console.

NOTE: If you do not know where to find the console, follow this:

Click Terminal from the top tab > New Terminal. This will pull up the console for you.

Make sure that the directory of your terminal is the place where your index.js file is at. If not, you can always use ls to list the different folders in that directory and cd to change into that directory as shown below: 

My terminal was in the Github folder and I used ls to list all the folders in the Github folder. From there, I can see the cafe-bot folder where my hello.js file is located in. So I used cd cafe-bot to move into that folder.

From there, type npm install discord.js

Once you’re done with that, once again, type node index.js.

[Sometimes you might run into errors that let you know that “The term node is not recognized as the name of a cmdlet”. This either means that you have NOT installed Node JS, in which you can go to this post to see how to do it HERE OR you might have some issues with directories in which you can look at this: https://www.youtube.com/watch?v=pg4t48BPmh8]

You should see “Bot is ready!” and with that, your bot is up!

Go ahead, explore it, enjoy it! You can do it!

HOW TO MAKE A DISCORD BOT THAT RESPONDS TO THINGS!!!

TRUST ME IT’S SUPER EASY!!! 

Pretty much every Discord bot tutorial I’ve seen is either outdated, way too complicated, or a video... so I’ve decided to take matters into my own hands and make my own tutorial!!!

So here’s how to make a response bot with Python and Repl.it, step by step, with pictures. (Dw, you don’t even need to know how to code, I’ll run you through everything!!)

Step 1: HAVE A DISCORD ACCOUNT AND A SERVER!

Seeing as you’re here, I’ll assume you know what discord is and have an account. I won’t explain this bit to you.

Step 2: MAKE A REPL.IT ACCOUNT 

Repl.it is where your bot’s code is gonna live, so you need to make an account for it!!

https://repl.it/signup?goto=%2F~.

Step 3: STARTING THE BOT!

Now you’re gonna go to https://discord.com/developers/applications and make an application!

Once you’re there, click that blue “New Application” button and make a new application!

Once you’ve done that, you should be here: 

Ok, now go to the “Bot” section and add a robot to this thing!!

Keep this tab open, we need it for the rest of the tutorial. 

Right, now we’re getting somewhere!!!!!

Step 4: ADDING THE BOT!

Now, you need to add the bot to a server! 

Go to the “General Information” page of your bot/ app, and copy the client ID

now, replace where this link says [YOUR CLIENT ID HERE] with your client ID and go to said link:

https://discordapp.com/api/oauth2/authorize?scope=bot&client_id=[YOUR CLIENT ID HERE]

(example: https://discord.com/oauth2/authorize?scope=bot&client_id=714083849235333161)

Authorise it, and bam! It’s in your server!

Step 5: ACTUALLY CODING THE BOT!!

FINALLY! 

This bit is REALLY easy, because I’ve made you some base code, so you don’t have to do much!!

Go to: https://repl.it/@stealingpotatos/tutorialbotbase1

Click the “fork” button, and you’ve got your own copy of the code!!!

Now, replace trigger word with whatever sentence/ word you’d like your bot to respond to. IT’S GOTTA BE IN LOWER CASE. IT WON’T WORK IF IT’S NOT.  

Then replace response with whatever you’d like your bot’s response to be!

But you’re not done yet!! Your bot still won’t work!!

For your bot to work, you’re gonna need to make a new file called “.env”

This is where your super secret bot token is gonna go! You’re putting it in a seperate file due to how repl.it code is public, and we don’t want people messing with your bot!

In your .env file, write “SUPER_SECRET_BOT_TOKEN=”, like this:

Now, we need to go back to your bot page, and copy the bot token 

Now, paste that bot token after “ SUPER_SECRET_BOT_TOKEN=“

(that’s a made up token by the way)

NOW YOU’RE DONE!!!!

Click that big green “run” button at the top, give it a minute, and test your bot!

I’M SUPER PROUD OF YOU, LOOK AT YOU GO!!!!

Your bot will respond to anyone saying the trigger word/ sentence in a message.

If it’s not working, double check you followed the tutorial right. If it’s still not working, send me a message or ask, and I’ll try to help you!!

Extras: KEEPING YOUR BOT ONLINE

Because of the “keep_alive” function, your bot will continue to be online for about an hour after you close the tab.

If you want to keep your bot online all the time, make an https://uptimerobot.com/ alert for the link in the bot alive page!

Extras: ADDING MORE TRIGGERS/RESPONSES

Super simple!! 

If you want multiple triggers for the same response, copy & paste the “(””) in message.content.lower()” part of the statement, add an or

Like that!

And for adding another trigger/response entirely, just copy & paste the statement entirely, and change the “if” to an “elif” if you don’t want both things to trigger at once.
