Reading and Writing Data Using the Sendinblue API

Hey there, fellow JavaScript wizards! Ready to dive into the world of Sendinblue API integration? Buckle up, because we're about to embark on a journey that'll supercharge your user-facing integrations with some serious data syncing magic.

Setting the Stage: Sendinblue API Client

First things first, let's get that Sendinblue API client up and running. It's as easy as pie:

npm install sib-api-v3-sdk

Now, let's authenticate and get this party started:

const SibApiV3Sdk = require('sib-api-v3-sdk');
const defaultClient = SibApiV3Sdk.ApiClient.instance;
defaultClient.authentications['api-key'].apiKey = 'YOUR_API_KEY';

Reading Data: Unleash the Power of Information

Time to flex those data-fetching muscles! Here's a nifty async function that'll grab your contact lists, contact details, and campaign stats in one fell swoop:

async function fetchSendinblueData() {
  const apiInstance = new SibApiV3Sdk.ContactsApi();
  const listInstance = new SibApiV3Sdk.ListsApi();
  const campaignInstance = new SibApiV3Sdk.EmailCampaignsApi();

  try {
    const contacts = await apiInstance.getContacts();
    const lists = await listInstance.getLists();
    const campaigns = await campaignInstance.getEmailCampaigns();

    return { contacts, lists, campaigns };
  } catch (error) {
    console.error('Oops! Something went wrong:', error);
  }
}

Writing Data: Make Your Mark

Now that we've got the reading part down, let's flex our writing muscles. Here's a slick function to update your contacts in batches:

async function batchUpdateContacts(contacts) {
  const apiInstance = new SibApiV3Sdk.ContactsApi();
  const batchSize = 50; // Adjust based on API limits

  for (let i = 0; i < contacts.length; i += batchSize) {
    const batch = contacts.slice(i, i + batchSize);
    const requestContactImport = new SibApiV3Sdk.RequestContactImport();
    requestContactImport.contacts = batch;

    try {
      await apiInstance.importContacts(requestContactImport);
      console.log(`Batch ${i / batchSize + 1} updated successfully!`);
    } catch (error) {
      console.error(`Error updating batch ${i / batchSize + 1}:`, error);
    }
  }
}

Real-time Data Sync: Stay in the Loop

Want to keep your finger on the pulse? Set up a webhook to handle Sendinblue events in real-time. Here's a quick Express.js endpoint to get you started:

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

app.post('/webhook', express.json(), (req, res) => {
  const event = req.body;
  
  switch (event.event) {
    case 'unsubscribed':
      // Handle unsubscribe
      break;
    case 'hard_bounce':
      // Handle bounce
      break;
    // Add more cases as needed
  }

  res.sendStatus(200);
});

Error Handling and Rate Limiting: Play Nice with the API

Remember, even APIs have bad days. Let's implement some retry logic and respect those rate limits:

async function apiCallWithRetry(apiCall, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await apiCall();
    } catch (error) {
      if (error.response && error.response.status === 429) {
        const retryAfter = error.response.headers['retry-after'] || 5;
        await new Promise(resolve => setTimeout(resolve, retryAfter * 1000));
      } else if (i === maxRetries - 1) {
        throw error;
      }
    }
  }
}

Optimizing Performance: Speed Demon Mode

Want to kick things up a notch? Here's a turbocharged batch sync function:

async function efficientBatchSync(data, syncFunction, batchSize = 100) {
  const batches = [];
  for (let i = 0; i < data.length; i += batchSize) {
    batches.push(data.slice(i, i + batchSize));
  }

  await Promise.all(batches.map(batch => syncFunction(batch)));
}

Testing and Debugging: Squash Those Bugs

Don't forget to test your API interactions! Here's a quick Jest test to get you started:

jest.mock('sib-api-v3-sdk');

test('fetchSendinblueData returns expected data', async () => {
  const mockContacts = { /* mock data */ };
  SibApiV3Sdk.ContactsApi.mockImplementation(() => ({
    getContacts: jest.fn().mockResolvedValue(mockContacts)
  }));

  const result = await fetchSendinblueData();
  expect(result.contacts).toEqual(mockContacts);
});

Best Practices and Security: Stay Safe Out There

Last but not least, keep those API keys secret, validate your data, and handle sensitive info with care. Your users will thank you!

// Don't do this!
const apiKey = 'abc123';

// Do this instead
const apiKey = process.env.SENDINBLUE_API_KEY;

And there you have it, folks! You're now armed and ready to tackle Sendinblue API integration like a pro. Remember, with great power comes great responsibility – use these skills wisely, and may your data always be in sync!

Happy coding! 🚀
