Step by Step Guide to Building an EmailOctopus API Integration in JS

Hey there, fellow dev! Ready to dive into the world of email marketing automation? Let's get our tentacles on the EmailOctopus API using the nifty email-octopus package. Buckle up, because we're about to make your email campaigns smoother than a squid's ink!

Prerequisites

Before we swim into the deep end, make sure you've got:

• Node.js and npm installed (you're a dev, so I'm betting you do)
• An EmailOctopus account with an API key (if not, go grab one real quick)

Setting Up the Project

Let's kick things off:

mkdir emailoctopus-integration
cd emailoctopus-integration
npm init -y
npm install email-octopus

Configuring the EmailOctopus Client

Time to import our new friend and get it ready:

const EmailOctopus = require('email-octopus');

const client = new EmailOctopus('YOUR_API_KEY');

Basic API Operations

List Management

Creating a list is a breeze:

client.lists.create({
  name: 'My Awesome List'
}).then(list => console.log(list));

Retrieving lists? Easy peasy:

client.lists.all().then(lists => console.log(lists));

Updating a list? No sweat:

client.lists.update('LIST_ID', {
  name: 'My Even More Awesome List'
}).then(list => console.log(list));

Contact Management

Adding a contact is like high-fiving an octopus - smooth and satisfying:

client.lists.contacts.create('LIST_ID', {
  email_address: '[email protected]',
  fields: {
    FirstName: 'Awesome',
    LastName: 'Developer'
  }
}).then(contact => console.log(contact));

Updating and removing contacts follow a similar pattern. You've got this!

Advanced Features

Want to handle campaigns, work with tags, or manage custom fields? The email-octopus package has got your back. Check out the docs for the nitty-gritty details.

Error Handling and Best Practices

Remember to handle those pesky rate limits and API errors:

client.lists.all()
  .then(lists => console.log(lists))
  .catch(error => {
    if (error.status === 429) {
      console.log('Whoa there, speedy! We hit a rate limit.');
    } else {
      console.error('Oops, something went wrong:', error);
    }
  });

Example Use Case: Building a Simple Subscription Form

Let's whip up a quick Express.js server to handle subscriptions:

const express = require('express');
const app = express();
const EmailOctopus = require('email-octopus');

const client = new EmailOctopus('YOUR_API_KEY');

app.use(express.json());

app.post('/subscribe', (req, res) => {
  const { email, firstName, lastName } = req.body;
  
  client.lists.contacts.create('LIST_ID', {
    email_address: email,
    fields: { FirstName: firstName, LastName: lastName }
  })
    .then(() => res.send('Welcome aboard!'))
    .catch(error => res.status(500).send('Oops, something went wrong'));
});

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

Testing and Debugging

Don't forget to use the EmailOctopus API sandbox for testing. It's like a kiddie pool for your code - safe and splash-free!

Wrapping Up

And there you have it! You've just built an EmailOctopus API integration faster than an octopus can change colors. Remember, the email-octopus package documentation is your best friend for diving deeper.
