Secure Your Seatable Webhooks with HMAC SHA256 Authentication
detail.loadingPreview
This n8n workflow template provides robust security for your Seatable webhooks by implementing HMAC SHA256 signature verification. Ensure the integrity and authenticity of incoming data before processing.
About This Workflow
Protect your Seatable data integrations with this essential n8n workflow. It leverages HMAC SHA256 to cryptographically verify the authenticity of incoming webhook requests. By calculating a signature based on your shared secret and the incoming payload, and then comparing it to the x-seatable-signature header, this workflow ensures that only legitimate requests are processed. If verification fails, the workflow immediately responds with a 403 Forbidden status, preventing unauthorized access or data manipulation. Successful verification allows the workflow to proceed to your custom data processing logic, offering a secure and reliable integration point.
Key Features
- HMAC SHA256 Verification: Cryptographically secures webhook endpoints by validating the signature of incoming requests.
- Automated Response: Responds with 200 OK on successful verification and 403 Forbidden on failure.
- Raw Body Handling: Captures the raw webhook body for accurate signature calculation.
- Customizable Integration: Easily extendable to integrate with your specific downstream processing logic.
- Template Ready: Designed as a starting point for secure Seatable webhook integrations.
How To Use
- Duplicate the Workflow: Copy this workflow template into your n8n instance.
- Configure Webhook Path: In the 'Seatable Webhook' node, update the
pathparameter to your desired webhook endpoint (e.g.,/your-unique-path). - Set Secret Key: In the 'Calculate sha256' node, replace the placeholder for the secret key with your actual shared secret provided by Seatable. Ensure this is kept secure.
- Connect Processing Logic: Replace the 'Add nodes for processing' NOOP node with your custom n8n nodes to handle the validated webhook data.
- Test: Trigger a webhook from Seatable and verify that it's correctly authenticated and processed.
