Secure API Endpoints: JWT Testing with Google Sheets & HTTP

Safeguard Your API Endpoints with JWT Testing and Google Sheets Integration

Unlock a robust layer of security for your API endpoints using JWT testing seamlessly integrated with Google Sheets. This n8n automation workflow conducts thorough security assessments by reading your endpoint information directly from Google Sheets, intelligently testing each endpoint with various token scenarios, and documenting the risk-scored results back into Google Sheets. Perfect for automation engineers and SaaS operators serious about API security.

What this workflow does

Our JWT Testing workflow systematically enhances your endpoint security through the following steps:

• Manual activation or an optional daily schedule initiates the security checks.
• Retrieves the specific Google Sheets document ID and the designated tabs for endpoints and results.
• Extracts active endpoint definitions from Google Sheets for testing.
• Utilizes each endpoint's JWT to generate various test tokens, including scenarios with no authentication, tampered payloads, and the 'alg:none' algorithm.
• Sends HTTP requests using these tokens, evaluating response status codes to identify security vulnerabilities like unauthorized access or accepted tampered tokens.
• Grades each endpoint's security, appending a detailed, timestamped risk analysis back into Google Sheets.

Use cases

This advanced workflow is ideal for:

• Security-conscious n8n users looking to automate API endpoint audits.
• Automation engineers aiming to integrate security checks into their regular workflows.
• SaaS operators who need reliable, documented security assessments for their API endpoints.

Technical details

This workflow leverages the following nodes and technologies:

• Google Sheets for retrieving and logging endpoint data and test results.
• HTTP request module for interacting with API endpoints.
• n8n nodes such as "if", "set", "code", "merge", "filter", and "sticky note" to process and evaluate API responses.

Enhance your API security measures effectively by incorporating this precise JWT Testing workflow into your n8n automation setup today.
