Secure Your Webhook with Robust Authentication and Validation
detail.loadingPreview
This n8n workflow snippet secures your incoming webhooks by implementing robust Bearer token authentication and validating essential request body fields. It ensures only authorized and properly formatted requests proceed, returning standardized error responses for unauthorized or malformed payloads.
About This Workflow
This n8n workflow template provides a foundational layer of security for your webhooks. It begins by establishing a secure connection using a configurable Bearer token. Upon receiving an incoming POST request to the /secure-webhook endpoint, it meticulously checks for the presence and validity of the Authorization header. If the authentication fails, a clear 401 Unauthorized JSON response is returned. Following authentication, the workflow proceeds to validate the request body against a defined set of required fields. Any missing fields will trigger a 400 Bad Request response. Only requests that successfully pass both authentication and validation will be processed further, allowing for a 200 OK success response to be returned. This template is designed to be easily extended with custom logic for post-validation operations.
Key Features
- Bearer Token Authentication: Ensures that only requests with a valid Bearer token in the Authorization header are processed.
- Customizable Required Fields: Define specific fields that must be present in the incoming request body for it to be considered valid.
- Standardized Error Responses: Returns clear and actionable JSON error messages for
401 Unauthorizedand400 Bad Requestscenarios. - Flexible Workflow Extension: Designed with a clear success path to seamlessly integrate additional custom logic.
How To Use
- Configure the
Configurationnode: Set your desiredconfig.bearerTokenvalue and define anyconfig.requiredFieldsby adding keys to therequiredFieldsobject (e.g.,config.requiredFields.messageto require amessagefield). - Set up the
Webhooknode: Ensure thepathis set to your desired endpoint (e.g.,/secure-webhook) and thehttpMethodisPOST. - Connect the nodes: Link the
Webhooknode to theCheck Authorization Headernode, then connect the branches of theifconditions to their respective errorrespondToWebhooknodes or the subsequent validation and success paths. - Extend the
Add workflow nodes heresection: Place your custom n8n nodes after theCheck Valid Requestnode to process successfully authenticated and validated requests.
