How to build a public Eventbrite integration: Building the Auth Flow

Aug 1, 2024 • 7 minute read

Hey there, fellow JavaScript enthusiast! Ready to dive into the world of Eventbrite integrations? Today, we're going to tackle the authorization flow for a public Eventbrite integration. Don't worry, it's not as daunting as it sounds. Let's get started!

Introduction

Eventbrite's API is a powerful tool for creating awesome event-related applications. But before we can start pulling event data or creating tickets, we need to set up a secure authentication process. This is where OAuth 2.0 comes in handy. It's like the bouncer at an exclusive club, making sure only the right people get in.

Prerequisites

Before we jump in, make sure you've got:

An Eventbrite Developer account with an API key (if you don't have one, go grab it!)
A Node.js environment set up with Express.js

Got all that? Great! Let's move on to the fun stuff.

OAuth 2.0 Flow Overview

We'll be using the Authorization Code Grant type of OAuth 2.0. It's like a secret handshake between your app and Eventbrite. Here's the gist:

Your app asks for permission
The user grants it
Eventbrite gives you a special code
You exchange that code for an access token
You use that token to make API requests

Simple, right? Let's break it down further.

Setting up the Authorization Request

First things first, we need to construct the authorization URL. It's like creating an invitation to our OAuth party. Here's what it looks like:

const authUrl = 'https://www.eventbrite.com/oauth/authorize?'
  + 'response_type=code'
  + '&client_id=YOUR_CLIENT_ID'
  + '&redirect_uri=YOUR_REDIRECT_URI';

Make sure to replace YOUR_CLIENT_ID and YOUR_REDIRECT_URI with your actual values. You can also add optional parameters like scope and state if you need them.

Handling the Redirect and Authorization Code

Once the user approves your request, Eventbrite will redirect them back to your specified URI with a special code. It's like they're returning from the club with the VIP pass. Let's set up an endpoint to catch this:

app.get('/callback', (req, res) => {
  const authCode = req.query.code;
  // Now we have the auth code!
});

Exchanging the Authorization Code for Access Token

Now that we have the auth code, it's time to trade it in for the real prize: the access token. This is like exchanging your VIP pass for an all-access backstage pass.

const axios = require('axios');

const tokenResponse = await axios.post('https://www.eventbrite.com/oauth/token', {
  code: authCode,
  client_id: YOUR_CLIENT_ID,
  client_secret: YOUR_CLIENT_SECRET,
  grant_type: 'authorization_code'
});

const accessToken = tokenResponse.data.access_token;

Implementing Token Refresh

Access tokens don't last forever. When they expire, you'll need to use the refresh token to get a new one. It's like renewing your backstage pass:

const refreshTokenResponse = await axios.post('https://www.eventbrite.com/oauth/token', {
  refresh_token: YOUR_REFRESH_TOKEN,
  client_id: YOUR_CLIENT_ID,
  client_secret: YOUR_CLIENT_SECRET,
  grant_type: 'refresh_token'
});

const newAccessToken = refreshTokenResponse.data.access_token;

Making Authenticated Requests to Eventbrite API

Now that you have your access token, you're ready to rock! Use it in your API requests like this:

const eventResponse = await axios.get('https://www.eventbriteapi.com/v3/users/me/events/', {
  headers: { 'Authorization': `Bearer ${accessToken}` }
});

Security Considerations

Remember, with great power comes great responsibility. Always use HTTPS, store your tokens securely, and be prepared to handle token revocation. Treat your tokens like you would your passwords!

Conclusion

And there you have it! You've successfully implemented the authorization flow for your Eventbrite integration. You're now ready to start building some amazing event-related features. The world of events is your oyster!
