Secure Token Verification Workflow

This n8n workflow is designed to handle and verify webhook requests securely. It starts with a webhook listener that triggers the process when a request is received. The workflow then uses a cryptographic node to generate a SHA256 HMAC hash of a query parameter (typically a CRC token) from the request, using a secret API key. The resulting hash is then formatted and stored in a variable. This process is useful for verifying the authenticity of incoming webhook requests, such as those from third-party services requiring CRC tokens for validation. It ensures secure communication and authenticity validation, making it ideal for integrating webhooks with secure data verification in WordPress or other web platforms.
