Step by Step Guide to Building a Lazada API Integration in Python

Introduction

Hey there, fellow developer! Ready to dive into the world of e-commerce integration? Today, we're tackling the Lazada API with Python. This powerhouse combo will let you tap into Southeast Asia's largest online marketplace. Whether you're managing products, handling orders, or keeping tabs on inventory, this guide's got you covered.

Prerequisites

Before we jump in, let's make sure you're geared up:

• Python 3.x installed (you're a pro, so I'm sure you've got this)
• Your favorite IDE or text editor
• requests library (pip install requests)
• Lazada API credentials (grab these from your Lazada seller account)

Authentication

First things first, let's get you authenticated:

import requests
import time

def get_access_token(app_key, app_secret, code):
    url = "https://auth.lazada.com/rest/auth/token/create"
    params = {
        "app_key": app_key,
        "app_secret": app_secret,
        "code": code
    }
    response = requests.get(url, params=params)
    return response.json()

# Use this to refresh your token when it expires
def refresh_token(app_key, app_secret, refresh_token):
    url = "https://auth.lazada.com/rest/auth/token/refresh"
    params = {
        "app_key": app_key,
        "app_secret": app_secret,
        "refresh_token": refresh_token
    }
    response = requests.get(url, params=params)
    return response.json()

Pro tip: Store your access token securely and refresh it before it expires. Your future self will thank you!

Basic API Structure

Lazada's API follows a RESTful structure. Here's a quick example to get you started:

def make_api_call(endpoint, access_token, params=None):
    base_url = "https://api.lazada.com/rest"
    headers = {
        "Authorization": f"Bearer {access_token}"
    }
    response = requests.get(f"{base_url}/{endpoint}", headers=headers, params=params)
    return response.json()

Core Functionalities

Product Management

Let's fetch some product info:

def get_product(access_token, item_id):
    endpoint = "product/item/get"
    params = {"item_id": item_id}
    return make_api_call(endpoint, access_token, params)

Order Management

Grab those orders:

def get_orders(access_token, created_after, status="unpaid"):
    endpoint = "orders/get"
    params = {
        "created_after": created_after,
        "status": status
    }
    return make_api_call(endpoint, access_token, params)

Inventory Management

Keep your stock in check:

def update_inventory(access_token, seller_sku, quantity):
    endpoint = "product/price_quantity/update"
    params = {
        "seller_sku": seller_sku,
        "quantity": quantity
    }
    return make_api_call(endpoint, access_token, params)

Error Handling and Best Practices

Always check the response code and handle errors gracefully:

def handle_api_response(response):
    if response.get("code") == "0":
        return response.get("data")
    else:
        raise Exception(f"API Error: {response.get('message')}")

Remember, Lazada has rate limits. Be a good API citizen and don't hammer their servers!

Advanced Features

Want to stay on top of real-time updates? Set up webhooks:

from flask import Flask, request

app = Flask(__name__)

@app.route('/lazada-webhook', methods=['POST'])
def lazada_webhook():
    data = request.json
    # Process the webhook data
    return "OK", 200

if __name__ == '__main__':
    app.run(port=5000)

Testing and Debugging

Lazada provides a sandbox environment. Use it! It's your playground to test without fear:

BASE_URL = "https://api.lazada.test/rest"  # Use this for sandbox testing

Log everything. Future you will be grateful when debugging:

import logging

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

logger.info("Making API call to %s", endpoint)

Deployment Considerations

When you're ready to go live:

1. Use environment variables for API credentials
2. Implement proper error handling and retries
3. Consider using a task queue for long-running operations

Conclusion

And there you have it! You're now armed with the knowledge to build a robust Lazada API integration. Remember, the API is your oyster – explore, experiment, and build something awesome!
