Validate API Requests with Bearer Token Authentication and Airtable

Bearer Token Validation

This n8n template helps you manage and validate tokens easily using:

• n8n as your backend workflow engine
• Airtable as your lightweight token store

🚀 What It Does

• Stores user tokens securely in Airtable with expiry or usage metadata.
• Validates incoming tokens in your workflows (e.g., webhook APIs).
• Rejects invalid or expired tokens automatically for security.
• Can be extended to generate, rotate, or revoke tokens for user management.

How It Works

1. Webhook node receives requests with a Bearer header.
2. Airtable Query looks up the provided token.
3. Validation Logic (Code node):
   • Checks if the token exists.
   • Verifies expiry or usage limits if configured.
4. Returns success if valid, or error if error with describing the issue.

• Note: This is the simplest way to do auth, just for simplification

Why Use This

• No need for a full backend to manage secure token validation.
• Clean, modular, and ready for your SaaS workflows.
