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

Hey there, fellow developer! Ready to supercharge your email validation game? Let's dive into integrating the NeverBounce API using JavaScript. This guide assumes you're already a coding wizard, so we'll keep things snappy and to the point.

Prerequisites

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

• Node.js and npm (you know the drill)
• A NeverBounce API key (grab one from their website if you haven't already)

Installation

First things first, let's get that package installed:

npm install neverbounce

Easy peasy, right?

Setting up the NeverBounce Client

Now, let's get that client up and running:

const NeverBounce = require('neverbounce');

const client = new NeverBounce({ apiKey: 'your_api_key_here' });

Boom! You're ready to roll.

Basic API Operations

Single Email Verification

Let's start with the bread and butter:

client.single.check({ email: '[email protected]' })
  .then(result => console.log(result))
  .catch(err => console.error(err));

Bulk Email Verification

Got a bunch of emails? No sweat:

const emails = ['[email protected]', '[email protected]'];
client.jobs.create(emails)
  .then(job => console.log(job))
  .catch(err => console.error(err));

Job Status Checking

Keep tabs on your bulk job:

client.jobs.status(jobId)
  .then(status => console.log(status))
  .catch(err => console.error(err));

Handling API Responses

The API will throw you some result codes. Here's the cheat sheet:

• 0: Valid
• 1: Invalid
• 2: Disposable
• 3: Catchall
• 4: Unknown

Remember to wrap your calls in try/catch blocks. The API can be moody sometimes!

Advanced Features

Webhook Integration

For the overachievers out there:

client.webhooks.create({
  url: 'https://your-webhook-url.com',
  event: 'job_completed'
})
  .then(webhook => console.log(webhook))
  .catch(err => console.error(err));

Rate Limiting

Don't go too crazy! NeverBounce has rate limits. Be a good API citizen and pace yourself.

Best Practices

• Cache your results. Your future self will thank you.
• Batch your requests when possible. It's more efficient and your wallet will love you for it.

Testing and Debugging

Use NeverBounce's test credentials to avoid burning through your quota. If things go sideways, double-check your API key and make sure you're not hitting any rate limits.

Wrapping Up

And there you have it! You're now a NeverBounce integration ninja. Remember, with great power comes great responsibility. Use your newfound email validation skills wisely!
