Reading and Writing Data Using the WhatConverts API

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

Introduction

WhatConverts API is your ticket to seamlessly integrating lead tracking and management into your applications. Whether you're building a custom dashboard or automating your marketing workflows, this API has got you covered.

Authentication: Your VIP Pass

First things first, let's get you authenticated:

1. Grab your API credentials from the WhatConverts dashboard.
2. Set up authentication in your JavaScript code:

const apiKey = 'your_api_key_here';
const headers = {
  'Authorization': `Bearer ${apiKey}`,
  'Content-Type': 'application/json'
};

Reading Data: Time to Fetch!

Fetching Leads

Let's grab those leads:

async function getLeads() {
  const response = await fetch('https://api.whatconverts.com/v1/leads', { headers });
  return await response.json();
}

Retrieving Specific Lead Details

Need to zero in on a particular lead? No problem:

async function getLeadDetails(leadId) {
  const response = await fetch(`https://api.whatconverts.com/v1/leads/${leadId}`, { headers });
  return await response.json();
}

Writing Data: Let's Create Some Magic

Creating New Leads

Time to add some fresh leads to the mix:

async function createLead(leadData) {
  const response = await fetch('https://api.whatconverts.com/v1/leads', {
    method: 'POST',
    headers,
    body: JSON.stringify(leadData)
  });
  return await response.json();
}

Updating Existing Leads

Got some changes? Let's update those leads:

async function updateLead(leadId, updatedData) {
  const response = await fetch(`https://api.whatconverts.com/v1/leads/${leadId}`, {
    method: 'PUT',
    headers,
    body: JSON.stringify(updatedData)
  });
  return await response.json();
}

Syncing Data: Keeping Everything in Harmony

Implementing a Sync Strategy

Here's a nifty function to keep your data in sync:

async function syncLeads(lastSyncTimestamp) {
  const leads = await getLeads();
  const newLeads = leads.filter(lead => new Date(lead.created_at) > lastSyncTimestamp);
  // Process new leads
  return new Date(); // Return current timestamp for next sync
}

Handling Pagination

Dealing with a ton of data? Pagination to the rescue:

async function getAllLeads() {
  let allLeads = [];
  let page = 1;
  let hasMore = true;

  while (hasMore) {
    const response = await fetch(`https://api.whatconverts.com/v1/leads?page=${page}`, { headers });
    const { leads, meta } = await response.json();
    allLeads = allLeads.concat(leads);
    hasMore = page < meta.total_pages;
    page++;
  }

  return allLeads;
}

Error Handling and Rate Limiting: Stay Cool Under Pressure

Always be prepared for the unexpected:

async function apiRequest(url, options) {
  try {
    const response = await fetch(url, { ...options, headers });
    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`);
    }
    if (response.headers.get('X-RateLimit-Remaining') < 10) {
      console.warn('API rate limit approaching, slow down!');
    }
    return await response.json();
  } catch (error) {
    console.error('API request failed:', error);
    // Handle error appropriately
  }
}

Optimizing Performance: Speed It Up!

Caching

Implement a simple cache to reduce API calls:

const cache = new Map();

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

function setCachedData(key, data) {
  cache.set(key, { data, timestamp: Date.now() });
}

Batch Operations

Need to update multiple leads? Batch 'em up:

async function batchUpdateLeads(leadsData) {
  const response = await fetch('https://api.whatconverts.com/v1/leads/batch', {
    method: 'PUT',
    headers,
    body: JSON.stringify({ leads: leadsData })
  });
  return await response.json();
}

Webhooks: Real-time Updates at Your Fingertips

Set up a webhook handler to receive real-time updates:

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

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

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

Testing and Debugging: Squash Those Bugs!

Always test your API interactions:

const assert = require('assert');

async function testGetLeads() {
  const leads = await getLeads();
  assert(Array.isArray(leads), 'getLeads should return an array');
  console.log('getLeads test passed!');
}

testGetLeads().catch(console.error);

Wrapping Up

And there you have it, folks! You're now equipped to read and write data like a pro using the WhatConverts API. Remember to keep your code clean, handle errors gracefully, and always be mindful of rate limits.

Keep experimenting, keep coding, and most importantly, have fun integrating! If you hit any snags, the WhatConverts documentation is your best friend. Now go forth and build something awesome! 🚀
