Reading and Writing Data Using the Sage 50 Accounting API

Hey there, fellow Javascript devs! Ready to dive into the world of Sage 50 Accounting API? Let's get our hands dirty with some data syncing for user-facing integrations. Buckle up!

Setting the Stage

Sage 50's API is your ticket to seamlessly integrating accounting data into your apps. Whether you're pulling customer info or pushing invoices, this API's got your back. And when it comes to user-facing integrations, keeping that data in sync is crucial. Let's explore how to make that happen.

Getting Cozy with Sage 50 API

First things first, let's set up shop:

const axios = require('axios');
const BASE_URL = 'https://api.sage50.com/v1';

const api = axios.create({
  baseURL: BASE_URL,
  headers: {
    'Authorization': `Bearer ${YOUR_API_KEY}`,
    'Content-Type': 'application/json'
  }
});

Easy peasy, right? Just remember to keep that API key safe!

Reading Data: The Scoop on Customers and Invoices

Time to fetch some data:

async function getCustomerData(customerId) {
  try {
    const response = await api.get(`/customers/${customerId}`);
    return response.data;
  } catch (error) {
    console.error('Oops! Customer data fetch failed:', error);
  }
}

Writing Data: Creating Customers and Invoices

Now, let's add some data to the mix:

async function createInvoice(invoiceData) {
  try {
    const response = await api.post('/invoices', invoiceData);
    return response.data;
  } catch (error) {
    console.error('Uh-oh! Invoice creation hiccup:', error);
  }
}

The Art of Data Sync

Syncing data is like conducting an orchestra. Here's a simple conductor:

async function syncData() {
  const lastSyncTimestamp = getLastSyncTimestamp();
  const updatedData = await fetchUpdatedData(lastSyncTimestamp);
  
  for (const item of updatedData) {
    await updateLocalData(item);
  }
  
  setLastSyncTimestamp(Date.now());
}

Pro tip: Run this bad boy on a schedule, and you're golden!

Turbocharging Your API Game

Remember, the API has limits. Let's play nice:

async function batchUpdate(items) {
  const batchSize = 50;
  for (let i = 0; i < items.length; i += batchSize) {
    const batch = items.slice(i, i + batchSize);
    await api.post('/batch', batch);
    await new Promise(resolve => setTimeout(resolve, 1000)); // Be a good API citizen
  }
}

When Things Go South: Error Handling

Errors happen. Let's catch 'em with style:

function apiErrorHandler(error) {
  if (error.response) {
    console.error(`API Error: ${error.response.status} - ${error.response.data.message}`);
  } else if (error.request) {
    console.error('No response received:', error.request);
  } else {
    console.error('Error setting up request:', error.message);
  }
}

Trust, but Verify: Testing Your Integration

A little testing goes a long way:

async function testCustomerSync() {
  const testCustomer = await createTestCustomer();
  await syncData();
  const localCustomer = getLocalCustomer(testCustomer.id);
  assert.deepEqual(testCustomer, localCustomer, 'Customer sync failed');
}

Keeping It Under Wraps: Security First

Last but not least, keep those secrets... secret:

// Use environment variables or a secure vault
const API_KEY = process.env.SAGE50_API_KEY;

Wrapping Up

And there you have it! You're now armed and ready to tackle Sage 50 API integrations like a pro. Remember, the key to a smooth integration is consistent syncing, robust error handling, and a sprinkle of performance optimization.

Keep experimenting, stay curious, and happy coding! 🚀
