Introduction

Hey there, fellow dev! Ready to supercharge your email marketing game? Let's dive into building a killer Campaign Monitor API integration using JavaScript. This guide will walk you through the process, assuming you're already a coding wizard. We'll keep things snappy and focus on the good stuff.

Prerequisites

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

Node.js and npm (you know the drill)
A Campaign Monitor API key (grab one from your account)
Your favorite code editor

Setting up the project

Let's get this party started:

mkdir campaign-monitor-integration
cd campaign-monitor-integration
npm init -y
npm install node-campaign-monitor

Authentication

Time to make friends with the API:

const CampaignMonitor = require('node-campaign-monitor');

const api = new CampaignMonitor({
  apiKey: 'your-api-key-here',
  clientId: 'your-client-id-here'
});

Basic API Operations

Fetching Lists

Let's see what lists we're working with:

api.lists.getActive((err, lists) => {
  if (err) console.error(err);
  console.log(lists);
});

Adding Subscribers

Time to grow that list:

const newSubscriber = {
  EmailAddress: '[email protected]',
  Name: 'New Subscriber',
  CustomFields: [
    { Key: 'Interests', Value: 'JavaScript, APIs' }
  ]
};

api.subscribers.add('list-id', newSubscriber, (err, result) => {
  if (err) console.error(err);
  console.log('Subscriber added:', result);
});

Creating Campaigns

Let's craft that perfect email:

const campaign = {
  Name: 'Awesome API Integration',
  Subject: 'Check out our new features!',
  FromName: 'Your Dev Team',
  FromEmail: '[email protected]',
  ListIDs: ['list-id-1', 'list-id-2'],
  // ... other campaign details
};

api.campaigns.create(campaign, (err, result) => {
  if (err) console.error(err);
  console.log('Campaign created:', result);
});

Handling Responses and Errors

Always expect the unexpected:

api.someMethod((err, result) => {
  if (err) {
    console.error('Oops!', err.message);
    // Handle the error gracefully
    return;
  }
  
  // Process the successful result
  console.log('Success!', result);
});

Advanced Features

Segmentation

Slice and dice your audience:

const segmentRules = [
  { Subject: 'EmailAddress', Clauses: ['CONTAINS @gmail.com'] }
];

api.lists.createCustomField('list-id', segmentRules, (err, result) => {
  if (err) console.error(err);
  console.log('Segment created:', result);
});

Automation Workflows

Set it and forget it:

// This is just a conceptual example, as automation workflows
// are typically set up via the Campaign Monitor UI
api.automations.create({
  name: 'Welcome Series',
  triggers: [{ type: 'subscribes_to_list', listId: 'list-id' }],
  actions: [
    { type: 'send_email', emailId: 'welcome-email-1' },
    { type: 'wait', duration: '3 days' },
    { type: 'send_email', emailId: 'welcome-email-2' }
  ]
}, (err, result) => {
  if (err) console.error(err);
  console.log('Automation created:', result);
});

Testing

Don't forget to test your integration:

const assert = require('assert');
const sinon = require('sinon');

describe('Campaign Monitor Integration', () => {
  it('should add a subscriber', (done) => {
    const addStub = sinon.stub(api.subscribers, 'add').yields(null, { success: true });
    
    api.subscribers.add('list-id', newSubscriber, (err, result) => {
      assert.ifError(err);
      assert.strictEqual(result.success, true);
      addStub.restore();
      done();
    });
  });
});

Best Practices

Respect rate limits (check the API docs for current limits)
Cache frequently accessed data
Keep your API key secret (use environment variables)
Implement proper error handling and logging

Conclusion

And there you have it! You're now armed with the knowledge to create a robust Campaign Monitor API integration. Remember, the API is your playground – experiment, optimize, and build something awesome. Happy coding!
