Reading and Writing Data Using the JustCall API

Hey there, fellow JavaScript wizards! Ready to dive into the world of JustCall API integration? Buckle up, because we're about to embark on a journey of seamless data synchronization that'll make your user-facing integrations sing.

The JustCall API: Your New Best Friend

JustCall's API is a powerhouse for managing call-related data. Whether you're building a CRM integration or a custom call analytics dashboard, this API has got your back. And the best part? It's designed with developers like us in mind.

Authentication: Getting the Keys to the Kingdom

First things first, let's get you authenticated. You'll need to grab your API credentials from the JustCall dashboard. Once you've got those, implementing OAuth 2.0 is a breeze:

const axios = require('axios');

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

Reading Data: Fetching the Good Stuff

User Information

Want to grab user details? Here's how you do it:

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

Call Logs

Need call logs? Say no more:

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

Pro tip: Use pagination to handle large datasets efficiently. Your users will thank you for the speedy load times!

Writing Data: Making Your Mark

Creating Contacts

Adding new contacts is a piece of cake:

async function createContact(accessToken, contactData) {
  const response = await axios.post('https://justcall.io/api/v1/contacts', contactData, {
    headers: { Authorization: `Bearer ${accessToken}` }
  });
  return response.data;
}

Updating Records

Need to update existing data? We've got you covered:

async function updateContact(accessToken, contactId, updateData) {
  const response = await axios.put(`https://justcall.io/api/v1/contacts/${contactId}`, updateData, {
    headers: { Authorization: `Bearer ${accessToken}` }
  });
  return response.data;
}

Real-time Sync: Keeping It Fresh

Webhook Magic

Webhooks are your friend for real-time updates. Set up your endpoint and let JustCall do the heavy lifting:

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

Polling Like a Pro

Sometimes, good old polling is the way to go. Here's a smart way to do it:

async function pollForUpdates(accessToken, interval = 60000) {
  setInterval(async () => {
    try {
      const updates = await getUpdates(accessToken);
      processUpdates(updates);
    } catch (error) {
      console.error('Polling error:', error);
    }
  }, interval);
}

Error Handling and Rate Limiting: Stay Cool Under Pressure

Always be prepared for API hiccups. Implement retry logic with exponential backoff:

async function retryRequest(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, 2 ** i * 1000));
    }
  }
}

Best Practices: The Cherry on Top

1. Cache smartly: Store frequently accessed data to reduce API calls.
2. Batch operations: Group multiple operations when possible to minimize requests.
3. Keep it consistent: Implement robust error handling to maintain data integrity across systems.

Wrapping Up

There you have it, folks! You're now armed with the knowledge to build killer integrations with the JustCall API. Remember, the key to a great user-facing integration is smooth data sync and snappy performance. Now go forth and code something awesome!
