Reading and Writing Data Using the LionDesk API

Hey there, fellow JavaScript devs! Ready to dive into the world of LionDesk API integration? Let's get our hands dirty with some data syncing for user-facing integrations. Buckle up!

Introduction

LionDesk's API is a powerhouse for real estate CRM integrations. When it comes to user-facing integrations, nailing that data sync is crucial. We're talking seamless experiences and happy users. So, let's jump in and see how we can make that happen.

Authentication: Your Key to the Kingdom

First things first – we need to get you authenticated. Here's the lowdown:

1. Grab your API credentials from LionDesk.
2. Implement OAuth 2.0 flow (it's not as scary as it sounds, promise!).

Here's a quick snippet to manage your tokens:

const refreshToken = async (refreshToken) => {
  const response = await fetch('https://api.liondesk.com/oauth2/token', {
    method: 'POST',
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
    body: `grant_type=refresh_token&refresh_token=${refreshToken}&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET`
  });
  return response.json();
};

Reading Data: Get What You Need

Fetching Contacts

The /contacts endpoint is your best friend here. Don't forget about pagination and filtering – they're lifesavers for large datasets.

const getContacts = async (accessToken, page = 1) => {
  const response = await fetch(`https://api.liondesk.com/contacts?page=${page}`, {
    headers: { 'Authorization': `Bearer ${accessToken}` }
  });
  return response.json();
};

Retrieving Tasks and Appointments

Same deal for tasks and appointments. Here's a quick example:

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

Writing Data: Make Your Mark

Creating and Updating Contacts

POST for new contacts, PUT for updates. Easy peasy!

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

Syncing Strategies: Keep It Fresh

Incremental Sync

Use the modified_since parameter to fetch only what's changed. Your users will thank you for the speed boost!

const getUpdatedContacts = async (accessToken, lastSyncTime) => {
  const response = await fetch(`https://api.liondesk.com/contacts?modified_since=${lastSyncTime}`, {
    headers: { 'Authorization': `Bearer ${accessToken}` }
  });
  return response.json();
};

Handling Conflicts

Compare timestamps and implement some smart conflict resolution. Trust me, it's worth the effort.

Error Handling and Rate Limiting: Play Nice

Don't let errors bring you down. Implement retry logic and respect those rate limits. Here's a simple example:

const apiCall = async (url, options, retries = 3) => {
  try {
    const response = await fetch(url, options);
    if (response.status === 429) {
      const retryAfter = response.headers.get('Retry-After');
      await new Promise(resolve => setTimeout(resolve, retryAfter * 1000));
      return apiCall(url, options, retries - 1);
    }
    return response.json();
  } catch (error) {
    if (retries > 0) return apiCall(url, options, retries - 1);
    throw error;
  }
};

Optimizing Performance: Speed Demon

Batch Operations

Why make 100 API calls when you can make one? Batch operations are your friend.

const batchUpdateContacts = async (accessToken, contacts) => {
  const response = await fetch('https://api.liondesk.com/contacts/batch', {
    method: 'PUT',
    headers: {
      'Authorization': `Bearer ${accessToken}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ contacts })
  });
  return response.json();
};

Wrapping Up

And there you have it! You're now armed with the knowledge to build a killer LionDesk API integration. Remember, the key is to keep your data fresh, handle errors gracefully, and always optimize for performance.
