Quick Guide to Realtime Data in Google Ad Manager without Webhooks

Hey there, fellow JavaScript devs! Ready to dive into the world of realtime data from Google Ad Manager without the hassle of webhooks? Let's get straight to it.

The Lowdown on Realtime Data

We all know the drill - users want up-to-the-minute data, and we want to deliver. While webhooks are great, sometimes you just want a simpler solution. That's where polling comes in handy.

Setting Up the Google Ad Manager API

First things first, let's get those API credentials sorted:

1. Head over to the Google Developers Console
2. Create a new project (or select an existing one)
3. Enable the Google Ad Manager API
4. Create credentials (OAuth 2.0 client ID)

Now, let's install the necessary library:

npm install googleapis

Polling: The Heart of Our Solution

Polling is like that friend who keeps asking "Are we there yet?" - annoying, but effective. Here's a basic polling function to get us started:

function poll(fn, interval) {
  setTimeout(() => {
    fn().then(() => poll(fn, interval));
  }, interval);
}

Fetching Data from the API

Time to put that polling to good use. We'll use the googleapis library to fetch data:

const { google } = require('googleapis');

async function fetchAdManagerData() {
  const auth = new google.auth.GoogleAuth({
    keyFile: 'path/to/your/credentials.json',
    scopes: ['https://www.googleapis.com/auth/dfp'],
  });

  const admanager = google.admanager({ version: 'v202305', auth });

  try {
    const res = await admanager.reports.run({
      // Your report request here
    });
    return res.data;
  } catch (error) {
    console.error('Error fetching data:', error);
  }
}

poll(fetchAdManagerData, 60000); // Poll every minute

Optimizing Polling Frequency

Don't be that overeager friend - let's be smart about how often we poll:

let pollInterval = 60000; // Start with 1 minute

function adaptivePolling() {
  fetchAdManagerData().then(data => {
    if (dataHasChanged(data)) {
      pollInterval = Math.max(pollInterval / 2, 10000); // Increase frequency, min 10 seconds
    } else {
      pollInterval = Math.min(pollInterval * 1.5, 300000); // Decrease frequency, max 5 minutes
    }
    setTimeout(adaptivePolling, pollInterval);
  });
}

adaptivePolling();

Handling API Responses

Now that we've got the data, let's make sense of it:

function processData(data) {
  const processedData = {
    impressions: data.rows[0].impressions,
    clicks: data.rows[0].clicks,
    revenue: data.rows[0].revenue,
  };
  updateUI(processedData);
}

Updating the UI

Keep your users in the loop with smooth UI updates:

function updateUI(data) {
  document.getElementById('impressions').textContent = data.impressions;
  document.getElementById('clicks').textContent = data.clicks;
  document.getElementById('revenue').textContent = `$${data.revenue.toFixed(2)}`;
}

Error Handling and Retry Logic

When things go south (and they will), be prepared:

async function fetchWithRetry(maxRetries = 3, delay = 1000) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fetchAdManagerData();
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      await new Promise(resolve => setTimeout(resolve, delay * Math.pow(2, i)));
    }
  }
}

Performance Considerations

Keep things snappy with some simple caching:

let cache = {};

async function fetchWithCache() {
  const now = Date.now();
  if (cache.data && now - cache.timestamp < 60000) {
    return cache.data;
  }
  const data = await fetchAdManagerData();
  cache = { data, timestamp: now };
  return data;
}

Wrapping Up

And there you have it! A straightforward way to get realtime(ish) data from Google Ad Manager without diving into the world of webhooks. Sure, it might not be as instantaneous, but it's simple, effective, and gets the job done.

Remember, polling has its pros (simplicity, ease of implementation) and cons (potential for increased API usage, slight delay in data). Choose wisely based on your specific needs.
