Validate API Requests with Bearer Token Authentication and Airtable

Description

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

Webhook node receives requests with a Bearer header.
Airtable Query looks up the provided token.
Validation Logic (Code node):
Checks if the token exists.
Verifies expiry or usage limits if configured.
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.

Enjoy building secure automations with n8n + Airtable! 🚀
