Quick Guide to Implementing Webhooks in Workflowy

Aug 16, 2024 • 7 minute read

Hey there, fellow Javascript devs! Ready to supercharge your Workflowy integration with some webhook magic? Let's dive right in and get those real-time updates flowing!

Introduction

Webhooks are the secret sauce that keeps your app in sync with Workflowy. They're like little messengers that tap you on the shoulder whenever something interesting happens. And with the Workflowy API, setting them up is a breeze.

Prerequisites

Before we start cooking, make sure you've got these ingredients:

A shiny Workflowy API key
Node.js installed on your machine
A dash of RESTful API knowledge

Got all that? Great! Let's roll up our sleeves and get to work.

Setting up the Webhook Endpoint

First things first, we need a place for Workflowy to send those juicy updates. Let's whip up a quick Express server:

const express = require('express');
const app = express();
app.use(express.json());

app.post('/webhook', (req, res) => {
  console.log('Webhook received:', req.body);
  res.sendStatus(200);
});

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

Boom! You've got a webhook endpoint ready to catch those Workflowy updates.

Registering the Webhook with Workflowy

Now, let's tell Workflowy where to send those updates. Here's how you register your webhook:

const axios = require('axios');

async function registerWebhook() {
  try {
    const response = await axios.post('https://workflowy.com/api/webhooks', {
      url: 'https://your-server.com/webhook',
      events: ['node_created', 'node_updated', 'node_deleted']
    }, {
      headers: { 'Authorization': 'Bearer YOUR_API_KEY' }
    });
    console.log('Webhook registered:', response.data);
  } catch (error) {
    console.error('Error registering webhook:', error);
  }
}

registerWebhook();

Just replace 'YOUR_API_KEY' with your actual API key, and you're good to go!

Handling Webhook Payloads

When Workflowy sends an update, it'll look something like this:

{
  "event": "node_created",
  "timestamp": "2023-06-15T12:34:56Z",
  "data": {
    "id": "abc123",
    "name": "New task",
    "parent_id": "def456"
  }
}

Let's update our webhook endpoint to handle this payload:

app.post('/webhook', (req, res) => {
  const { event, data } = req.body;
  
  switch (event) {
    case 'node_created':
      console.log(`New node created: ${data.name}`);
      break;
    case 'node_updated':
      console.log(`Node updated: ${data.id}`);
      break;
    case 'node_deleted':
      console.log(`Node deleted: ${data.id}`);
      break;
  }
  
  res.sendStatus(200);
});

Implementing User-Facing Features

Now, let's make this useful for your users. How about sending them a real-time notification when a new task is created?

const WebSocket = require('ws');
const wss = new WebSocket.Server({ port: 8080 });

app.post('/webhook', (req, res) => {
  const { event, data } = req.body;
  
  if (event === 'node_created') {
    wss.clients.forEach((client) => {
      if (client.readyState === WebSocket.OPEN) {
        client.send(JSON.stringify({
          type: 'new_task',
          name: data.name
        }));
      }
    });
  }
  
  res.sendStatus(200);
});

Your frontend can now connect to this WebSocket and show snazzy notifications!

Security Considerations

Don't forget to keep things secure! Here's a quick way to verify that the webhook is really from Workflowy:

const crypto = require('crypto');

function verifySignature(payload, signature) {
  const hash = crypto.createHmac('sha256', 'YOUR_WEBHOOK_SECRET')
                     .update(payload)
                     .digest('hex');
  return hash === signature;
}

app.post('/webhook', (req, res) => {
  const signature = req.headers['x-workflowy-signature'];
  
  if (!verifySignature(JSON.stringify(req.body), signature)) {
    return res.status(401).send('Invalid signature');
  }
  
  // Process the webhook...
});

Testing and Debugging

Testing webhooks locally can be tricky, but tools like ngrok are here to save the day. It creates a public URL for your local server, perfect for webhook testing.

If things aren't working, double-check your API key, make sure your server is reachable, and keep an eye on those Workflowy API docs for any changes.

Best Practices

Remember to:

Handle errors gracefully
Implement retry logic for failed webhook deliveries
Keep an eye on your webhook subscriptions and clean up any you're not using

Conclusion

And there you have it! You're now a Workflowy webhook wizard. With this power, you can keep your app in perfect sync with Workflowy, providing your users with a seamless, real-time experience.
