Step by Step Guide to Building a Shopee API Integration in JS

Introduction

Hey there, fellow dev! Ready to dive into the world of Shopee API integration? You're in for a treat. Shopee's API is a powerhouse for e-commerce, and mastering it can seriously level up your game. Let's get cracking!

Prerequisites

Before we jump in, make sure you've got:

• Node.js and npm (you're probably already best buds with these)
• A Shopee Partner account (if you don't have one, go grab it!)
• Your API key and secret (keep these safe, they're your golden tickets)

Setting up the project

Alright, let's lay the groundwork:

mkdir shopee-api-integration
cd shopee-api-integration
npm init -y
npm install axios crypto-js

Easy peasy, right? We're using axios for HTTP requests and crypto-js for generating signatures.

Authentication

Now for the fun part - getting that access token:

const crypto = require('crypto-js');

function generateSignature(partnerId, apiKey, apiSecret, timestamp) {
  const baseString = partnerId + apiKey + timestamp;
  return crypto.HmacSHA256(baseString, apiSecret).toString();
}

// Use this to get your access token

Pro tip: Store that access token securely. You'll need it for every request.

Making API requests

Here's where the magic happens:

const axios = require('axios');

async function makeApiRequest(endpoint, params) {
  try {
    const response = await axios.post(`https://partner.shopeemobile.com/api/v2${endpoint}`, params, {
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${YOUR_ACCESS_TOKEN}`
      }
    });
    return response.data;
  } catch (error) {
    console.error('API request failed:', error);
    throw error;
  }
}

Core API functionalities

Let's tackle some key operations:

Product management

async function getProductList() {
  return await makeApiRequest('/product/get_item_list', {
    // Add necessary params
  });
}

Order management

async function getOrderDetails(orderSn) {
  return await makeApiRequest('/order/get_order_detail', {
    order_sn_list: [orderSn]
  });
}

Webhook integration

Shopee loves to keep you in the loop. Set up a webhook endpoint and let the data flow:

app.post('/shopee-webhook', (req, res) => {
  const event = req.body;
  // Handle the event based on its type
  console.log('Received webhook:', event);
  res.sendStatus(200);
});

Rate limiting and best practices

Shopee's got limits, so play nice:

const rateLimit = require('express-rate-limit');

const apiLimiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100 // limit each IP to 100 requests per windowMs
});

app.use('/api/', apiLimiter);

Testing and debugging

Postman is your best friend here. Create a collection, save your requests, and test away. And don't forget to log everything - future you will thank present you.

Deployment considerations

When you're ready to go live:

• Use environment variables for API credentials
• Implement proper error handling and logging
• Consider using a service like PM2 for process management

Conclusion

And there you have it! You're now armed and dangerous with Shopee API integration skills. Remember, the API docs are your north star - keep them close.

Happy coding, and may your integration be ever smooth and your errors be few!
