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

Introduction

Hey there, fellow developer! Ready to dive into the world of Landingi API integration? You're in for a treat. This guide will walk you through the process of building a robust integration using JavaScript. Landingi's API is a powerful tool that allows you to programmatically manage landing pages, forms, and leads. Let's get started!

Prerequisites

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

• Node.js installed (latest LTS version)
• A Landingi account with API access
• Your favorite code editor

Oh, and don't forget to grab your API key from the Landingi dashboard. You'll need it for authentication.

Setting Up the Development Environment

First things first, let's set up our project:

mkdir landingi-integration
cd landingi-integration
npm init -y
npm install axios dotenv

We're using axios for HTTP requests and dotenv for environment variable management. Trust me, it'll make our lives easier.

Authentication

Now, let's handle authentication. Create a .env file in your project root:

LANDINGI_API_KEY=your_api_key_here

And here's how we'll use it:

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

const landingiApi = axios.create({
  baseURL: 'https://api.landingi.com/v1',
  headers: { 'X-Api-Key': process.env.LANDINGI_API_KEY }
});

Making API Requests

With our setup complete, let's make our first request:

async function getLandingPages() {
  try {
    const response = await landingiApi.get('/landing_pages');
    console.log(response.data);
  } catch (error) {
    console.error('Error fetching landing pages:', error.response.data);
  }
}

getLandingPages();

Core API Functionalities

Let's implement some core functionalities:

// Create a new landing page
async function createLandingPage(data) {
  const response = await landingiApi.post('/landing_pages', data);
  return response.data;
}

// Update an existing page
async function updateLandingPage(id, data) {
  const response = await landingiApi.put(`/landing_pages/${id}`, data);
  return response.data;
}

// Delete a page
async function deleteLandingPage(id) {
  await landingiApi.delete(`/landing_pages/${id}`);
}

Working with Forms and Leads

Handling form submissions and leads is a breeze:

// Fetch form submissions
async function getFormSubmissions(formId) {
  const response = await landingiApi.get(`/forms/${formId}/submissions`);
  return response.data;
}

// Create a new lead
async function createLead(data) {
  const response = await landingiApi.post('/leads', data);
  return response.data;
}

Implementing Webhooks

Webhooks are your friends for real-time updates. Here's a simple Express server to handle them:

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

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

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

Error Handling and Best Practices

Always wrap your API calls in try-catch blocks and handle rate limiting:

async function safeApiCall(apiFunction) {
  try {
    return await apiFunction();
  } catch (error) {
    if (error.response && error.response.status === 429) {
      console.log('Rate limit hit. Retrying in 60 seconds...');
      await new Promise(resolve => setTimeout(resolve, 60000));
      return safeApiCall(apiFunction);
    }
    throw error;
  }
}

Testing and Debugging

Don't forget to test your integration! Here's a simple test using Jest:

test('getLandingPages returns data', async () => {
  const pages = await getLandingPages();
  expect(pages).toBeDefined();
  expect(Array.isArray(pages)).toBe(true);
});

Deployment Considerations

When deploying, remember:

• Keep your API key secure (use environment variables)
• Implement proper error logging
• Consider using a caching layer for frequently accessed data

Conclusion

And there you have it! You've just built a solid Landingi API integration. Remember, this is just the beginning. The API offers many more endpoints and functionalities to explore. Keep experimenting, and don't hesitate to dive into the official Landingi API documentation for more advanced features.

Happy coding, and may your landing pages convert like crazy! 🚀
