Click on the tabs above to navigate directly to your desired topic. Each section includes conceptual explanations, interactive examples, and code snippets required for actual API calls. Interact directly to grasp the principles of API integration.
Mastering the HTTP Request Node
The HTTP Request node is at the core of all API integrations. It is crucial to understand how to correctly configure the URL, method, headers, and body. Use the interactive builder below to see how each element works in a real API request.
Request Components
Select the method appropriate for your operation (e.g., POST for creating data, GET for retrieving, PUT for updating, DELETE for removing).
Used to pass metadata like authentication tokens or content types.

In-depth Analysis: LinkedIn API Integration
The LinkedIn API is a powerful tool for professional networking automation, but its access methods and authentication processes can be complex. We'll explore the limitations of the official API, alternatives, and specific automation examples using n8n.
Authentication Method Comparison
Accessing the official LinkedIn API often requires 'Partner Program' approval, which presents a high barrier to entry. This leads many users to consider simpler third-party APIs as alternatives. The chart below illustrates the relative complexity of each method.

In-depth Analysis: Notion API Integration
The Notion API allows you to automate document and database management. Understand Notion's unique authentication and permission models, and learn how to build powerful productivity workflows with n8n.
Core Principle: Granular Security
Even after creating an API integration token, Notion requires you to 'share' that integration with the specific pages or databases you want to automate. This is a strong security measure to minimize damage if a token is compromised. Before making API calls, always check your page sharing settings.

Best Practices for Robust Workflows
To build powerful and maintainable automation workflows, it's crucial to follow a few key principles. Error handling, adhering to API rate limits, and secure credential management are essential.
Wait node to add intentional delays (e.g., 1-2 seconds) between API calls. This is the best way to prevent service blockages or account suspensions.{{ $credentials.yourCredentialName.propertyName }}. This enhances security and simplifies credential management.
