Validate Bearer Token API Requests with Airtable

This n8n workflow provides a robust solution for Bearer token authentication in API requests. It uses a Webhook node to receive incoming requests, extracts the Bearer token from the Authorization header, and queries an Airtable base to verify the token's validity. A Code node performs detailed checks for token existence, expiration dates, usage limits, and active status via an IF node.

If valid, the workflow proceeds to authorized actions; otherwise, it returns an error response with specifics like 'Token expired' or 'Invalid token'. This modular setup eliminates the need for a custom backend, leveraging Airtable's simplicity for token management.

Ideal for SaaS apps, Real Estate MLS integrations, or any webhook-based API needing secure access control. Benefits include automated security, easy scalability, token rotation potential, and time savings on auth implementation. Extend it for user management, logging, or multi-tenant apps.
