Reading and Writing Data Using the Hubspot Marketing Hub API

Hey there, fellow JavaScript wizards! Ready to dive into the world of Hubspot Marketing Hub API? Let's get our hands dirty with some data syncing for user-facing integrations. Buckle up, because we're about to make your life a whole lot easier.

Authentication: Your Golden Ticket

First things first, we need to get past the bouncer. Hubspot uses OAuth 2.0, so let's set that up real quick:

const axios = require('axios');

async function getAccessToken(code) {
  const response = await axios.post('https://api.hubapi.com/oauth/v1/token', {
    grant_type: 'authorization_code',
    client_id: YOUR_CLIENT_ID,
    client_secret: YOUR_CLIENT_SECRET,
    redirect_uri: YOUR_REDIRECT_URI,
    code: code
  });
  return response.data.access_token;
}

Keep that token safe, you'll need it for all your API adventures!

Reading Data: The Art of Fetching

Now that we're in, let's grab some data. Here's how you can fetch contacts:

async function getContacts(accessToken) {
  const response = await axios.get('https://api.hubapi.com/crm/v3/objects/contacts', {
    headers: { Authorization: `Bearer ${accessToken}` }
  });
  return response.data.results;
}

Easy peasy, right? You can use similar patterns for lists and campaigns. Just swap out the endpoint and you're good to go.

Writing Data: Time to Make Your Mark

Writing data is just as straightforward. Here's how you can create or update a contact:

async function upsertContact(accessToken, properties) {
  const response = await axios.post('https://api.hubapi.com/crm/v3/objects/contacts', {
    properties
  }, {
    headers: { Authorization: `Bearer ${accessToken}` }
  });
  return response.data;
}

Syncing Strategies: Keep It Fresh

Real-time updates? Webhooks are your best friend:

app.post('/webhook', (req, res) => {
  const { object_id, properties } = req.body;
  // Handle the update
  res.sendStatus(200);
});

For periodic syncing, set up a cron job to poll the API. Just remember to play nice with those rate limits!

Error Handling: When Things Go Sideways

Always expect the unexpected. Wrap your API calls in try-catch blocks and log those errors:

try {
  const contacts = await getContacts(accessToken);
} catch (error) {
  console.error('Failed to fetch contacts:', error.response.data);
}

Best Practices: Work Smarter, Not Harder

Cache data when you can, and batch your API calls to minimize requests. Your users (and Hubspot) will thank you.

Testing and Debugging: Trust, but Verify

Unit test your API interactions and use Hubspot's sandbox environment. It's like a playground, but for code!

Performance Optimization: Speed Demon

For lightning-fast syncing, embrace parallel processing:

const contacts = await Promise.all(contactIds.map(id => getContact(accessToken, id)));

Wrapping Up

And there you have it! You're now armed and dangerous with the Hubspot Marketing Hub API. Remember, with great power comes great responsibility (and awesome integrations). Now go forth and sync like a pro!
