Step by Step Guide to Building a Kartra API Integration in JS

Introduction

Hey there, fellow developer! Ready to dive into the world of Kartra API integration? You're in for a treat. Kartra's API is a powerful tool that lets you tap into their marketing automation platform, and we're going to build something cool with it using JavaScript. Let's get cracking!

Prerequisites

Before we jump in, make sure you've got:

• A Kartra account with API credentials (you're not a wizard, Harry, you need those keys!)
• Node.js and npm installed on your machine (because, duh, we're doing JS)
• A solid grasp of JavaScript and REST APIs (I know you've got this!)

Setting Up the Project

Alright, let's get our hands dirty:

mkdir kartra-api-integration
cd kartra-api-integration
npm init -y
npm install axios dotenv

Boom! Project initialized. We're using axios for HTTP requests and dotenv to keep our secrets... well, secret.

Authentication

First things first, let's keep those API credentials safe. Create a .env file:

KARTRA_API_KEY=your_api_key
KARTRA_API_PASSWORD=your_api_password

Now, let's create an authentication function:

require('dotenv').config();
const axios = require('axios');

const authenticate = () => {
  return {
    api_key: process.env.KARTRA_API_KEY,
    api_password: process.env.KARTRA_API_PASSWORD
  };
};

Making API Requests

Time to make some noise! Here's a basic GET request:

const makeRequest = async (endpoint, method = 'GET', data = {}) => {
  const url = `https://app.kartra.com/api/${endpoint}`;
  const auth = authenticate();
  
  try {
    const response = await axios({
      method,
      url,
      data: { ...auth, ...data }
    });
    return response.data;
  } catch (error) {
    console.error('API request failed:', error);
    throw error;
  }
};

Implementing Key Kartra API Endpoints

Let's put our makeRequest function to work:

// Get leads
const getLeads = () => makeRequest('lead/query');

// Create a contact
const createContact = (contactData) => makeRequest('lead/create', 'POST', contactData);

// Update a campaign
const updateCampaign = (campaignId, campaignData) => 
  makeRequest(`campaign/update/${campaignId}`, 'PUT', campaignData);

// Get orders
const getOrders = () => makeRequest('order/query');

Error Handling and Rate Limiting

Remember, be nice to the API. Let's add some rate limiting:

const sleep = (ms) => new Promise(resolve => setTimeout(resolve, ms));

const makeRateLimitedRequest = async (...args) => {
  try {
    const result = await makeRequest(...args);
    await sleep(1000); // Wait 1 second between requests
    return result;
  } catch (error) {
    if (error.response && error.response.status === 429) {
      console.log('Rate limited. Waiting before retry...');
      await sleep(5000);
      return makeRateLimitedRequest(...args);
    }
    throw error;
  }
};

Testing the Integration

Time to put our code through its paces:

const runTests = async () => {
  try {
    const leads = await makeRateLimitedRequest('lead/query');
    console.log('Leads:', leads);

    const newContact = await makeRateLimitedRequest('lead/create', 'POST', {
      email: '[email protected]',
      first_name: 'Test',
      last_name: 'User'
    });
    console.log('New contact:', newContact);

    // Add more tests as needed
  } catch (error) {
    console.error('Test failed:', error);
  }
};

runTests();

Best Practices and Optimization

To keep things speedy:

1. Cache frequently accessed data
2. Use batch operations when possible
3. Implement pagination for large data sets

Conclusion

And there you have it! You've just built a Kartra API integration in JS. Pretty cool, right? Remember, this is just the tip of the iceberg. There's so much more you can do with Kartra's API.
