Connect Any App with HTTP Requests

The HTTP Request node is a universal connector in n8n that lets you call any web API endpoint. Use it when you need to integrate with a service that doesn't have a dedicated n8n node, when you need to access a specific API endpoint not covered by existing nodes, or when you want to scrape data from websites.

It gives you complete control over API calls with custom headers, authentication, and parameters. Unlike pre-built nodes that simplify common operations, HTTP Request nodes require more configuration but offer unlimited flexibility.

• Perfect for niche SaaS tools without standard connectors
• Essential for accessing custom/internal APIs
• Great for web scraping and data extraction tasks

Most APIs require authentication. For HTTP Request nodes, you typically use API keys in headers (like 'Authorization: Bearer YOUR_KEY'), basic authentication with username/password, or OAuth 2.0. The workflow template includes examples of setting authentication headers.

Always store sensitive credentials in n8n's credential system rather than hardcoding them in your workflow. For OAuth flows, you may need to set up initial authorization separately, then use refresh tokens in your automated calls.

• API keys go in request headers
• Use n8n credentials for secure storage
• Test authentication separately before building full workflows

Pre-built nodes are easier to use with pre-configured operations and authentication, but they only cover specific services and endpoints. HTTP Request nodes require more setup but work with ANY web service. The trade-off is flexibility vs convenience.

For common services like Google Sheets or Slack, use pre-built nodes for simplicity. For niche tools, custom APIs, or web scraping, use HTTP Request nodes. Many businesses use a combination: pre-built nodes for mainstream services and HTTP Request nodes for everything else.

• Pre-built: easier, limited to supported services
• HTTP Request: more setup, works with anything
• Choose based on your specific integration needs

Many APIs limit responses to 50-100 items per request. To get all data, you need pagination handling. This template shows how to check for 'next page' tokens or links in API responses, increment page numbers, and loop until all data is retrieved.

The key is examining the API response for pagination indicators—some APIs include a 'next' URL, others use page numbers with total page counts. Implement a loop that continues until no more data is available, being careful to respect API rate limits between calls.

• Check for 'next_page' or 'cursor' fields in responses
• Implement loops with exit conditions
• Add delays between calls to avoid rate limiting

Yes, HTTP Request nodes can fetch webpage HTML, which you can then parse with n8n's HTML Extract node. This template includes a web scraping example that fetches a Wikipedia page and extracts the article title.

For production scraping, add rate limiting to avoid overwhelming target sites, respect robots.txt files, and handle dynamic content that might require browser automation instead of simple HTTP requests. Always consider the legal and ethical implications of scraping particular websites.

• Combine HTTP Request with HTML Extract nodes
• Add delays between requests
• Check website terms before scraping

Common challenges include handling API rate limits, managing authentication token expiration, parsing different response formats (JSON, XML, CSV), dealing with API version changes, and error handling when APIs are temporarily unavailable.

This template demonstrates best practices like implementing retry logic, storing pagination state, and validating responses before processing data further. Always build robust error handling since external APIs can fail unexpectedly.

• Implement retry logic for failed calls
• Monitor for API version changes
• Validate data before processing
