How to Get Reddit API Key: Finally, a Guide That Works

All I wanted was data. Reddit data. And like every good adventure, this story begins with a map (read guides), mission, and a total misunderstanding of how OAuth2 works. I’m not even close to being a Reddit API expert, but here is my story for you to learn from (that is bound to save your time and nerves). Just read it to the end. So, let me walk you through the process, decode the terminology, drop a few memes, and make sure you don’t rage-quit your project.

Step 1. How to Get Reddit API Key or Where The Adventure Begins

The very first step on your journey to Reddit data is creating an account, in case you haven't one yet. After, to access Reddit’s API, you also need to register an app. This gives you the Reddit API credentials the platform uses to identify and authorize your requests.

So, log into your Reddit account and head to the app creation page. Scroll down and choose to create a new app by filling out the form:

• Name your app;
• Select the type of your app: 
  
  • “script” – for personal use, backend tools, or automation that only need a single user’s access;
  • “web app” – for apps with user-facing interfaces that use browser-based login and redirection;
  • “installed app” – also for multi-user or public-facing applications and desktop/mobile clients.
• Set a redirect URI — even though you won’t use it for the script type, it’s required;
• Fill further fields (if you have time, wish, and patience). 

Once submitted, Reddit will generate your app’s credentials — including a client_ID and client_secret. Hooray! You’ve now opened the door. Next, we’ll look at the tools you’ve just received.

Step 2. Reddit API Keys: Three Sacred Artifacts

Once you’ve registered your Reddit app, you’ll be given a few essential pieces of information. These are your Reddit API keys — identifiers and credentials that Reddit uses to authenticate and authorize your requests. Without them, you won’t get far.

• Client ID is your app’s public identifier. Reddit uses it to recognize which application is making the request. You’ll find it just beneath the name of your app on the Reddit apps page. It’s usually a short alphanumeric string, something like abcDEF123XYZ78.
• Client Secret is the private key tied to your app. It’s used in combination with the client ID to verify that your app is legitimate. Keep it safe. Don’t share it, commit it to GitHub, or expose it in any frontend code. If it ever leaks, treat it like a password: revoke it and generate a new one.
• User-Agent is a custom string that tells Reddit who you are and is required in every request. Unlike the first two that are generated when you register your app, the User-Agent isn’t issued by Reddit — you create it yourself. It must be unique, descriptive, and human-readable. If your user agent is too vague (or missing), your requests may be throttled or blocked.

These are the essentials Reddit uses to recognize and authorize your application.

No matter the size of your project, it’s best to avoid hard-coding credentials in source files. Instead, use environment variables, secrets managers, or configuration files like .env that are kept out of version control. This minimizes security risks and simplifies deployment to different environments.

These Reddit API keys don’t give you access by themselves. Yep. They are needed to get permission through the scopes. So, once you’ve got your credentials sorted, the next step is to decide exactly what kind of access you want — and that means understanding Reddit’s scopes.

Ready? Let’s move further.

Step 3. Reddit API Access: Decoding the Scopes or Middle of the Way

So, you’ve got your keys — your Client ID, Client Secret, and User-Agent. Now it’s time to decide what those keys should open. In Reddit’s world, that means selecting your scopes.

Scopes define what your app can do and what data it can access as soon as Reddit doesn’t give you full access by default — you have to ask for it explicitly, and you only get what you request.

Not all scopes are created equal. Some scopes let you read public data like subreddit posts. Others let you vote, comment, or see a user’s post history — things that require deeper, authenticated access like a successful OAuth login with permission from the Reddit account. 

For example, you can select the following scopes:

• read — read subreddit posts and comments;
• identity — view your Reddit username and account info;
• submit — submit new posts and comments;
• vote — upvote and downvote content;
• history — access your voting and comment history;
• mysubreddits — see the subreddits you’re subscribed to.

Think of scopes as your API access menu. You check the boxes for the actions you need, and Reddit gives you a token that only works for those things. Ask for too little, and your request might fail. Ask for too much, and Reddit might raise an eyebrow.

The important thing to remember is: no scope, no access. Even with valid Reddit API access token and credentials, if your scope is missing or wrong, Reddit won’t let the request through.

So, the best way is to start small. For most read-only use cases, read and identity are enough. Add more as your app evolves. And yes — technically, you can request all scopes with a wildcard (*) during development. But don’t do this in production unless you like surprises.

Once you’ve chosen your scopes, you’re ready to request a Reddit API access token and actually log in — which brings us to the fun part, called OAuth2.

Ready for the real action? Let’s go.

Step 4. Reddit API Login: It’s OAuth2, Baby, Not You

You've got your credentials. You’ve chosen your scopes. Now it's time to put them to work — and that means logging in. But Reddit API login isn’t your average username-and-password situation — Reddit uses OAuth2, an authentication protocol that can trip up even seasoned developers.

Depending on your app type, there are a few OAuth2 flows Reddit supports. For personal use and scripts, the simplest option is the password grant flow. It’s not recommended for public apps, but for solo developers just trying to access their own data (or public subreddit data), it’s the fastest way to get a working token. You send your Reddit username, password, and app credentials to Reddit’s token endpoint. In return, you get a Reddit access token.

That Reddit API token is what you’ll use to make authenticated API requests. No token, no data. Reddit expects it in the Authorization header of each call. 

Just keep in mind: the Reddit API access token is only valid for 1 hour. After that, you’ll need to request a new one. For short scripts or quick integrations, that’s usually fine. For anything long-running or high-frequency, you’ll want to automate the refresh process — or consider using a more advanced OAuth2 flow like:

• Authorization Code Grant used for web apps and third-party integrations. Redirects users to Reddit for login and consent.
• Implicit Grant used for browser-based apps (less secure, rarely recommended).
• Refresh Token Flow used to get a new access token without re-authenticating the user, applicable with the code grant only.

Once you've got your Reddit access token, you're ready to call the API for real. Next step: putting it all together and finally making requests. Let’s do it.

Step 5. Reddit API Credentials and Token: Assembling the Puzzle to Get Data Access

So far, you’ve collected credentials, chosen your scopes, and used them to get an access token. That’s the heavy lifting done. Now it’s time to connect the dots — and actually make requests to Reddit’s API and retrieve data (finally!).

At this point, here’s what you’ve got in your backpack:

• Client ID
• Client Secret
• User-Agent
• Access Token

These four work together to authenticate and authorize your API calls. To access Reddit data, you’ll now send requests to Reddit’s OAuth-protected endpoints — not the public reddit.com, but https://oauth.reddit.com. Every request needs to include:

• Your access token, added to the Authorization header;
• Your custom User-Agent, just like before.

That’s it. With those in place, Reddit will process your requests as long as your token is valid, and your scopes allow the action. You have at least 1 hour for that.

Step 6. Reddit API Token, Credentials, Keys… Skip All That — Use Data365.co Instead

If you’ve made it this far, you’ve survived Reddit’s official API initiation: developer accounts, app setup, OAuth2, scopes, tokens — and just enough ambiguity in the docs to question your life choices.

That path works. But it’s not built for speed — or simplicity.

But what if we say that you could skip all of that? 

“Could I? Skip OAuth? Scopes? Tokens? Really?” — will you ask.

Yes. Really. Wondering how to access Reddit data without using the official API? And here is the answer, Data365 Social Media API is a good choice out of plenty of tools offered.

If what you actually need is Reddit data — clean, structured, and ready for analysis — then Data365.co gives you a faster, smarter way in.

Data365’s Social Media API for Reddit gives you real-time access to Reddit post and public user data — without tokens to refresh, scopes to manage, or docs that contradict the platform’s behavior.
