Reading and Writing Data Using the HubSpot API

Hey there, fellow JavaScript devs! Ready to dive into the world of HubSpot API integration? Let's get our hands dirty with some code and learn how to sync data like pros.

Setting Up HubSpot API Access

First things first, you'll need to get your API keys. Head over to your HubSpot developer account and grab those credentials. We'll be using OAuth 2.0 for authentication because, let's face it, it's 2023 and we're not savages.

const hubspot = require('@hubspot/api-client');
const hubspotClient = new hubspot.Client({ accessToken: 'YOUR_ACCESS_TOKEN' });

Reading Data from HubSpot

Alright, let's fetch some data! We'll start with contacts, but the same principles apply to companies and deals.

async function getAllContacts() {
  const limit = 100;
  let after = undefined;
  let allContacts = [];

  do {
    const apiResponse = await hubspotClient.crm.contacts.basicApi.getPage(limit, after);
    allContacts = allContacts.concat(apiResponse.results);
    after = apiResponse.paging?.next?.after;
  } while (after);

  return allContacts;
}

Pro tip: Always handle pagination and respect those rate limits. HubSpot's not gonna be happy if you hammer their API!

Writing Data to HubSpot

Now, let's push some data back to HubSpot. Batch operations are your friend here – they're faster and more efficient.

async function updateCompanies(companies) {
  const batchInputSimplePublicObjectInput = { inputs: companies.map(company => ({
    id: company.id,
    properties: {
      name: company.name,
      domain: company.domain
    }
  }))};

  try {
    const apiResponse = await hubspotClient.crm.companies.batchApi.update(batchInputSimplePublicObjectInput);
    console.log('Companies updated successfully');
    return apiResponse;
  } catch (e) {
    e.message === 'HTTP request failed'
      ? console.error(JSON.stringify(e.response, null, 2))
      : console.error(e);
  }
}

Implementing Real-Time Data Sync

Webhooks are your best friend for real-time updates. Set them up in your HubSpot account and handle them like this:

app.post('/webhook', (req, res) => {
  const event = req.body;
  if (event.subscriptionType === 'contact.propertyChange') {
    // Handle contact update
    updateLocalContact(event.objectId, event.propertyName, event.propertyValue);
  }
  res.sendStatus(200);
});

function updateLocalContact(contactId, propertyName, propertyValue) {
  // Update your local database or trigger other actions
  console.log(`Updating contact ${contactId}: ${propertyName} = ${propertyValue}`);
}

Handling Data Conflicts and Error Scenarios

Always expect the unexpected. Implement retry logic and handle those pesky API errors:

async function retryOperation(operation, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await operation();
    } catch (error) {
      if (error.response && error.response.status === 429) {
        // Rate limited, wait and retry
        await new Promise(resolve => setTimeout(resolve, 1000 * (i + 1)));
      } else if (i === maxRetries - 1) {
        throw error; // Max retries reached, rethrow
      }
    }
  }
}

Optimizing Performance

Caching is your secret weapon. Here's a simple in-memory cache to get you started:

const cache = new Map();

function getCachedData(key, fetchFunction, ttl = 60000) {
  if (cache.has(key) && Date.now() - cache.get(key).timestamp < ttl) {
    return cache.get(key).data;
  }

  const data = fetchFunction();
  cache.set(key, { data, timestamp: Date.now() });
  return data;
}

Testing and Debugging

Unit tests are your safety net. Here's a quick example using Jest:

jest.mock('@hubspot/api-client');

test('getAllContacts fetches all contacts', async () => {
  const mockGetPage = jest.fn()
    .mockResolvedValueOnce({ results: [{ id: '1' }], paging: { next: { after: '1' } } })
    .mockResolvedValueOnce({ results: [{ id: '2' }], paging: {} });

  hubspotClient.crm.contacts.basicApi.getPage = mockGetPage;

  const contacts = await getAllContacts();

  expect(contacts).toEqual([{ id: '1' }, { id: '2' }]);
  expect(mockGetPage).toHaveBeenCalledTimes(2);
});

Best Practices and Considerations

Remember, with great power comes great responsibility. Always keep security in mind, especially when handling user data. When syncing across systems, consider using a queue system for large datasets to avoid overwhelming your servers or hitting API limits.

Wrapping Up

There you have it, folks! You're now armed with the knowledge to build robust HubSpot integrations. Remember, the key is to always think about efficiency, error handling, and keeping your data in sync. Now go forth and code some awesome integrations!

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