Secure Your API with n8n's Advanced Authentication Workflow
detail.loadingPreview
Implement robust API key authentication for your webhooks using n8n. This workflow demonstrates how to validate incoming API keys and control access to your sensitive endpoints.
About This Workflow
Safeguard your n8n workflows with this comprehensive API key authentication solution. Designed for developers and operations teams, this workflow establishes a secure gateway for your webhook endpoints. It begins by defining a webhook that requires an x-api-key header for access. The incoming API key is then cross-referenced against a registered list of valid keys, ensuring only authorized requests proceed. Successful authentication grants access, returning a success status with the user ID, while invalid or missing keys are met with a 401 unauthorized response. This template provides a foundational layer of security for any API-driven integration.
Key Features
- API Key Validation: Rigorously checks incoming
x-api-keyheaders against a defined list of authorized keys. - Customizable Access Control: Easily manage and update your registered API keys within the workflow.
- Secure Endpoint Protection: Prevents unauthorized access to your webhook endpoints.
- Clear Success/Error Responses: Provides distinct feedback for authenticated and unauthenticated requests.
How To Use
- Set up your registered API keys: In the "Registered API Keys" node, populate the
registered_api_keysarray with your valid user IDs and their corresponding API keys. - Configure the Secured Webhook: In the "Secured Webhook" node, ensure the
pathandhttpMethodmatch your desired endpoint. - Define Authentication: Set the
authenticationin the "Secured Webhook" toheaderAuthand associate it with your n8n credentials. - Test the Workflow: Use the "Test Secure Webhook" node to send a POST request with a valid
x-api-keyheader to verify the success path. - Deploy and Integrate: Once tested, deploy your n8n workflow and integrate it with your applications, ensuring they send the correct
x-api-keyin their requests.
