Reading and Writing Data Using the Salesmsg API

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

Authentication: Your Golden Ticket

First things first, you'll need to grab your API credentials from Salesmsg. Once you've got those, let's set up authentication:

const axios = require('axios');

const api = axios.create({
  baseURL: 'https://api.salesmsg.com/v1',
  headers: {
    'Authorization': `Bearer YOUR_API_KEY_HERE`,
    'Content-Type': 'application/json'
  }
});

Reading Data: Fetch Like a Boss

Time to pull some data! Let's fetch conversations and messages:

async function getConversations() {
  try {
    const response = await api.get('/conversations');
    return response.data;
  } catch (error) {
    console.error('Error fetching conversations:', error);
  }
}

async function getMessages(conversationId) {
  try {
    const response = await api.get(`/conversations/${conversationId}/messages`);
    return response.data;
  } catch (error) {
    console.error('Error fetching messages:', error);
  }
}

Pro tip: Don't forget to handle pagination for large datasets!

Writing Data: Make Your Mark

Sending messages and creating conversations is a breeze:

async function sendMessage(conversationId, message) {
  try {
    const response = await api.post(`/conversations/${conversationId}/messages`, {
      body: message
    });
    return response.data;
  } catch (error) {
    console.error('Error sending message:', error);
  }
}

async function createConversation(phoneNumber, message) {
  try {
    const response = await api.post('/conversations', {
      to: phoneNumber,
      body: message
    });
    return response.data;
  } catch (error) {
    console.error('Error creating conversation:', error);
  }
}

Real-time Sync: Stay in the Loop

Webhooks are your best friend for real-time updates. Here's a quick Express.js example:

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

app.post('/webhook', express.json(), (req, res) => {
  const event = req.body;
  
  switch (event.type) {
    case 'message.created':
      console.log('New message:', event.data);
      break;
    case 'conversation.updated':
      console.log('Conversation updated:', event.data);
      break;
    // Handle other event types
  }

  res.sendStatus(200);
});

Error Handling and Rate Limiting: Play Nice

Always implement retry logic and respect 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'] || 1;
        await new Promise(resolve => setTimeout(resolve, retryAfter * 1000));
      } else if (i === maxRetries - 1) {
        throw error;
      }
    }
  }
}

Optimizing Performance: Speed Demon

Cache frequently accessed data and use batch operations when possible:

const NodeCache = require('node-cache');
const cache = new NodeCache({ stdTTL: 600 }); // 10 minutes TTL

async function getCachedConversations() {
  const cachedData = cache.get('conversations');
  if (cachedData) return cachedData;

  const conversations = await getConversations();
  cache.set('conversations', conversations);
  return conversations;
}

Testing and Debugging: Smooth Sailing

Use Salesmsg's sandbox environment for testing, and don't be afraid to log generously during development. Your future self will thank you!

Wrapping Up

There you have it, folks! You're now equipped to build a killer Salesmsg integration. Remember, the key to a great sync is balancing real-time updates with efficient API usage. Now go forth and code something awesome!

Happy coding, and may your API calls always return 200 OK! 🚀
