Mastering HTTP Requests: A Comprehensive n8n Guide
detail.loadingPreview
This comprehensive n8n workflow serves as an excellent tutorial for understanding and utilizing the HTTP Request node effectively. It demonstrates three crucial patterns: splitting API responses into individual items, extracting specific data from HTML pages, and gracefully handling API pagination.
About This Workflow
Dive deep into the power of n8n's HTTP Request node with this detailed example workflow. Designed for both beginners and experienced users, it demystifies common challenges in API integration. Learn to transform bulk API responses into manageable items, efficiently scrape data from web pages using HTML extraction, and implement robust pagination logic to fetch all necessary data from multi-page APIs. This workflow is an interactive guide, inviting you to execute it step-by-step and inspect the data flow to truly grasp its mechanics.
Key Features
- API Response Itemization: Learn to convert monolithic JSON array responses into individual n8n items for easier processing.
- Web Data Extraction: Master fetching web pages via HTTP requests and precisely extracting data using CSS selectors with the HTML Extract node.
- Robust API Pagination: Implement a complete pagination loop using HTTP Request, Set, and If nodes to navigate through paginated API endpoints.
- Interactive Learning: Execute the workflow and inspect node outputs to understand data transformations in real-time.
