Reading and Writing Data Using the Proposify API

Hey there, fellow JavaScript devs! Ready to dive into the world of Proposify API integration? Let's get our hands dirty with some code and learn how to sync data like pros.

The Lowdown on Proposify API

Proposify's API is your ticket to seamlessly integrating proposal management into your app. We're talking about creating, updating, and fetching proposals programmatically. Cool, right?

Authentication: Your All-Access Pass

First things first, you'll need to grab your API credentials. Head over to your Proposify account settings and generate those keys.

If you're dealing with OAuth 2.0, here's a quick snippet to get you started:

const getAccessToken = async (clientId, clientSecret, code) => {
  const response = await fetch('https://api.proposify.com/oauth/token', {
    method: 'POST',
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
    body: `grant_type=authorization_code&client_id=${clientId}&client_secret=${clientSecret}&code=${code}`
  });
  return response.json();
};

Reading Data: Fetching Those Proposals

Let's grab some proposals, shall we? Here's how you can fetch a list:

const getProposals = async (accessToken) => {
  const response = await fetch('https://api.proposify.com/v1/proposals', {
    headers: { 'Authorization': `Bearer ${accessToken}` }
  });
  return response.json();
};

Need details on a specific proposal? No sweat:

const getProposalDetails = async (accessToken, proposalId) => {
  const response = await fetch(`https://api.proposify.com/v1/proposals/${proposalId}`, {
    headers: { 'Authorization': `Bearer ${accessToken}` }
  });
  return response.json();
};

Writing Data: Create and Update Like a Boss

Creating a new proposal is a breeze:

const createProposal = async (accessToken, proposalData) => {
  const response = await fetch('https://api.proposify.com/v1/proposals', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${accessToken}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify(proposalData)
  });
  return response.json();
};

Updating? Just as easy:

const updateProposal = async (accessToken, proposalId, updateData) => {
  const response = await fetch(`https://api.proposify.com/v1/proposals/${proposalId}`, {
    method: 'PUT',
    headers: {
      'Authorization': `Bearer ${accessToken}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify(updateData)
  });
  return response.json();
};

Syncing Data: Real-Time Magic

Webhooks are your best friend for real-time updates. Set up an endpoint in your app:

app.post('/proposify-webhook', (req, res) => {
  const eventData = req.body;
  // Process the webhook payload
  console.log('Received webhook:', eventData);
  res.sendStatus(200);
});

Error Handling and Rate Limiting: Stay Cool Under Pressure

Always wrap your API calls in try-catch blocks and implement retry logic for transient errors:

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

Respect those rate limits, folks! Implement a queue system if you're making lots of requests.

Optimizing Performance: Speed It Up

Caching is your friend. Store frequently accessed data locally and refresh it periodically:

const cache = new Map();

const getCachedData = async (key, fetchFn, ttl = 300000) => {
  if (cache.has(key) && Date.now() - cache.get(key).timestamp < ttl) {
    return cache.get(key).data;
  }
  const data = await fetchFn();
  cache.set(key, { data, timestamp: Date.now() });
  return data;
};

Testing and Debugging: Sandbox Fun

Use Proposify's sandbox environment for testing. It's like a playground, but for code!

Log your API calls for easy debugging:

const logApiCall = (method, url, data) => {
  console.log(`API Call: ${method} ${url}`);
  console.log('Data:', JSON.stringify(data, null, 2));
};

Wrapping Up

There you have it! You're now equipped to build a killer Proposify integration. Remember to keep your code clean, your errors handled, and your data synced. Happy coding, and may your proposals always be accepted!
