Secure Webhook Verification with HMAC-SHA256
detail.loadingPreview
This workflow provides a robust solution for securely verifying incoming webhooks using HMAC-SHA256 cryptography. It automatically processes challenge tokens, generates a hashed response, and confirms webhook ownership for various platform integrations.
About This Workflow
This n8n workflow is designed for securely handling webhook challenge-response mechanisms, a critical step for authenticating webhooks from many external services like social media platforms or payment gateways. It initiates with a Webhook node to receive incoming requests, extracts a challenge token (e.g., crc_token), and then uses the Crypto node to compute an HMAC-SHA256 hash of this token with a configurable secret key. Finally, the Set node formats the cryptographic output into a specific response token, ensuring the integrity and authenticity of your webhook endpoint. This setup is essential for maintaining secure and reliable automated integrations.
Key Features
- HMAC-SHA256 Hashing: Leverage industry-standard cryptographic hashing for robust data integrity and authentication.
- Automated Challenge-Response: Effortlessly respond to webhook verification challenges without manual intervention.
- Configurable Secret Key: Easily secure your webhook endpoints with your unique API key secret.
- Base64 Encoded Output: Ensures the generated hash is in a standard, easily consumable format.
- Streamlined Token Extraction: Automatically pulls specific challenge tokens from incoming webhook queries.
How To Use
- Configure the Webhook:
- Activate the "Webhook" node. The
pathparameter0db0a40c-e5d1-463f-8252-03599f1303e6will be part of your unique webhook URL. - Note the generated test URL or production URL for your integration.
- Activate the "Webhook" node. The
- Set Your API Key Secret:
- In the "Crypto" node, locate the
Secretfield. - Replace
"API KEY SECRET"with your actual secret key provided by the external service you are integrating with. - Ensure the
valuefield={{$json["query"]["crc_token"]}}correctly references the challenge token name expected by your service.
- In the "Crypto" node, locate the
- Understand the Response:
- The "Set" node takes the securely hashed output from the "Crypto" node and formats it as
sha256={{hashed_value}}. This is the exact format required by many challenge-response systems. - The
keepOnlySetoption ensures only this verification token is returned, keeping the response clean and precise.
- The "Set" node takes the securely hashed output from the "Crypto" node and formats it as
- Test and Deploy:
- Save the workflow and test it by sending a sample challenge-response request from your integrated service.
- Once verified, activate the workflow for production use.
