Reading and Writing Data Using the Teachable API

Hey there, fellow JavaScript devs! Ready to dive into the world of Teachable API? Let's get our hands dirty with some code and learn how to sync data for a user-facing integration. Buckle up!

Authentication: Your Key to the Kingdom

First things first, we need to get our API credentials. Head over to your Teachable admin panel and grab those keys. Now, let's implement OAuth 2.0 flow:

const axios = require('axios');

async function getAccessToken(clientId, clientSecret, code) {
  const response = await axios.post('https://accounts.teachable.com/oauth/token', {
    client_id: clientId,
    client_secret: clientSecret,
    code: code,
    grant_type: 'authorization_code'
  });
  return response.data.access_token;
}

Easy peasy, right? Now we're ready to rock and roll!

Reading Data: What's in the Box?

Let's fetch some user info and course data. Here's how you can get a user's enrolled courses:

async function getUserCourses(accessToken, userId) {
  const response = await axios.get(`https://api.teachable.com/v1/users/${userId}/courses`, {
    headers: { Authorization: `Bearer ${accessToken}` }
  });
  return response.data.courses;
}

Writing Data: Time to Make Some Changes

Updating profiles and enrolling users is a breeze. Check out this snippet for enrolling a user in a course:

async function enrollUserInCourse(accessToken, userId, courseId) {
  await axios.post(`https://api.teachable.com/v1/enrollments`, {
    user_id: userId,
    course_id: courseId
  }, {
    headers: { Authorization: `Bearer ${accessToken}` }
  });
}

Syncing Data: Keeping Everything in Harmony

Real-time updates? We've got you covered with webhooks. Here's a quick example of setting up a webhook listener:

const express = require('express');
const app = express();

app.post('/webhook', express.json(), (req, res) => {
  const event = req.body;
  console.log('Received webhook:', event);
  // Process the event
  res.sendStatus(200);
});

app.listen(3000, () => console.log('Webhook listener running on port 3000'));

Don't forget to handle those pesky rate limits and pagination. Your users will thank you!

Error Handling and Best Practices: Stay Sharp!

Always be prepared for API errors. Implement retry logic and use caching to keep things smooth:

async function apiCallWithRetry(fn, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      await new Promise(resolve => setTimeout(resolve, 1000 * Math.pow(2, i)));
    }
  }
}

Advanced Topics: Level Up Your Game

For those hungry for more, look into batch operations and queue systems for handling large-scale operations. Your API game will be unstoppable!

Wrapping Up

And there you have it, folks! You're now armed with the knowledge to conquer the Teachable API. Remember, practice makes perfect, so get out there and start coding. The world of seamless data integration awaits!

Happy coding, and may your API calls always return 200 OK! 🚀
