Today, we’ll follow the OKEX tutorial video to learn how to align data from web pages with data obtained via REST API interfaces. Join Xiao Mei in this step-by-step guide!
Key Learning Points
Understanding Web Data Structures
- Analyze HTML elements and their attributes.
- Identify dynamic content loaded via JavaScript.
Working with REST APIs
- Retrieve data using endpoints (e.g.,
GET /api/v1/data). - Parse JSON/XML responses for relevant fields.
- Retrieve data using endpoints (e.g.,
Data Synchronization Techniques
- Map web UI elements to API response fields.
- Handle pagination, rate limits, and authentication.
Error Handling
- Manage HTTP status codes (e.g.,
404,500). - Implement retries for failed requests.
- Manage HTTP status codes (e.g.,

| Step | Web Element | API Field | Notes |
|------|------------|----------|-------|
| 1 | Price Table | market_data.last_price | Uses WebSocket for real-time updates. |
| 2 | Order Book | order_book.bids/asks | Ensure timestamp alignment. |
| 3 | Trade History | trades[].price | Pagination required for large datasets. |
FAQ Section
Q1: How do I authenticate API requests?
A: Use API keys with HMAC-SHA256 signing. Store keys securely.
Q2: Why is my web data out of sync with the API?
A: Caching or delayed updates may cause discrepancies. Use Cache-Control headers.
Q3: Can I use Python for this integration?**
A: Yes! Libraries like requests and BeautifulSoup simplify HTTP and HTML parsing.
Q4: How to handle rate limits?
A: Implement exponential backoff or use WebSocket streams for high-frequency data.

Best Practices
- Modular Code: Separate data fetching (API) from rendering (Web).
- Logging: Track API calls and response times for debugging.
- Testing: Validate with mock data before production deployment.
By mastering these techniques, you’ll ensure seamless data flow between web interfaces and backend systems. Happy coding!
