Reading and Writing Data Using the Leadpages API

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

Authentication: Your Golden Ticket

First things first, we need to get you authenticated. Grab your API credentials from Leadpages and let's implement that OAuth 2.0 flow:

const axios = require('axios');

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

Reading Data: Fetching the Goods

Now that we're in, let's grab some user data:

async function getUserProfile(accessToken) {
  const response = await axios.get('https://api.leadpages.io/v1/users/me', {
    headers: { Authorization: `Bearer ${accessToken}` },
  });
  return response.data;
}

Want leads? We've got you covered:

async function getLeads(accessToken, page = 1, limit = 100) {
  const response = await axios.get('https://api.leadpages.io/v1/leads', {
    headers: { Authorization: `Bearer ${accessToken}` },
    params: { page, limit },
  });
  return response.data;
}

Pro tip: Keep an eye on those rate limits, and paginate like a champ!

Writing Data: Making Your Mark

Time to create some leads:

async function createLead(accessToken, leadData) {
  const response = await axios.post('https://api.leadpages.io/v1/leads', leadData, {
    headers: { Authorization: `Bearer ${accessToken}` },
  });
  return response.data;
}

Updating is just as easy:

async function updateLead(accessToken, leadId, updateData) {
  const response = await axios.put(`https://api.leadpages.io/v1/leads/${leadId}`, updateData, {
    headers: { Authorization: `Bearer ${accessToken}` },
  });
  return response.data;
}

Remember, always validate your data before sending it off!

Syncing Data: Real-time Magic

Let's set up a webhook listener with Express:

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

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

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

Optimizing Performance: Speed Demon

Caching is your friend. Implement it wisely:

const NodeCache = require('node-cache');
const cache = new NodeCache({ stdTTL: 600 }); // Cache for 10 minutes

async function getCachedLeads(accessToken) {
  const cacheKey = 'leads';
  let leads = cache.get(cacheKey);
  if (!leads) {
    leads = await getLeads(accessToken);
    cache.set(cacheKey, leads);
  }
  return leads;
}

Error Handling and Logging: Stay Informed

Don't let errors catch you off guard:

async function safeApiCall(apiFunction) {
  try {
    return await apiFunction();
  } catch (error) {
    console.error('API Error:', error.response?.data || error.message);
    // Log to your preferred logging service
    throw error;
  }
}

Security Considerations: Lock It Down

Store those API credentials securely, and implement rate limiting on your end to play nice with Leadpages' servers.

Testing and Debugging: Smooth Sailing

Use Leadpages' sandbox environment for testing, and leverage tools like Postman for API debugging. Your future self will thank you!

Wrapping Up

And there you have it! You're now equipped to build a robust Leadpages API integration. Remember to keep your code clean, your errors handled, and your data synced. Happy coding, and may your leads be ever-flowing!
